Consumers get food in many ways. They can purchase their food from a convenience store, grocery store, or supermarket, grow or raise their own food, or receive food through a food pantry or other hunger relief program when needed. Often, an individual consumer will have access to more food than they can eat in a day and so it will need to be stored until it is used. This publication will address how you can safely store your food for optimal quality until you are ready to use and consume it.

Failure to adequately wash hands is a major cause of infectious diseases. Individuals who practice poor personal hygiene while preparing food may spread diseases such as hepatitis A, salmonellosis, and shigellosis. Studies indicate that one-third (33%) of people do not wash their hands after using the restroom. This publication addresses the proper way to wash your hands.

Communicating positively with young children helps them develop confidence, feelings of self‑worth, and good relationships with others. It also helps make life with young children more pleasant for children and parents.

Child care providers who are good facilitators of the social development of young children also understand the relationship between child care curriculum, care giver demeanor, and discipline in promoting responsibility and a sense of community among young children.

There is a set of principles that characterizes the pattern and process of growth and development. These principles or characteristics describe typical development as a predictable and orderly process; that is, we can predict how most children will develop and that they will develop at the same rate and at about the same time as other children. Although there are individual differences in children’s personalities, activity levels, and timing of developmental milestones, such as ages and stages, the principles and characteristics of development are universal patterns.

As adults, we are usually busy as parents and workers and often feel stressed and experience burn-out at times, but would you ever think that children can experience stress too?

When caregivers are asked to talk about the stress in their lives, they frequently identify their emotions first rather than a specific problem or situation. While recognizing emotions is an important step to maintaining positive emotional health, identifying the situations or events that are problematic is the key to managing stress and preventing caregiver burnout.

Long-distance care may begin slowly with simple tasks such as listening to a problem over the telephone or helping with household chores during a visit. It can also start suddenly in response to a medical crisis. Regardless of how care begins, the role of the long-distance carer is likely to evolve over time as the needs of their loved one change.

When we need assistance, studies suggest there is a pattern to our help-seeking behaviors. For help during short periods of time, we generally turn first to our informal network (spouse and children, followed by friends and neighbors). When help is needed over long periods of time, we tend to turn to a formal network of agencies and organizations for assistance (Suitor and Pillemer, 1990).

This publication provides information about basic concepts and approaches used in making decisions on behalf of others or planning for ones own future needs. Read on to understand important concepts about decision making and strategies, including representative payees, powers of attorney, trusts, and guardianship.

Horses do not speak in words, but they still communicate. They use body language. Understanding horse “language” is important when it comes to safely handling horses. There are several ways horses position their bodies in order to talk to each other.

Our primary objectives in the Share-the-Fun program are to encourage 4-H members to: 1) discover and develop their talents and 2) to develop confidence in self and performing before others. This score sheet is designed to have judges evaluate 4-H members’ performances, give members feedback to assist with their continuous development, and assist in the selection of acts that can be used in an exciting, entertaining variety show.

Virginia 4-H offers a wide variety of opportunities beyond the local level that enable teens to develop the knowledge, skills, attitudes, and aspirations needed for success. However, before we involve teens in opportunities such as State 4-H Cabinet, State 4-H Congress, Virginia 4-H All Stars, Citizenship Washington Focus, National 4-H Congress, and National 4-H Conference, we — as 4-H professionals — must be sure the teens are adequately prepared for such ventures. This fact sheet provides tips on how to prepare your teens for district, state, national, and international 4-H opportunities.

This project book is intended for use by enrolled members of the 4-H program. 4-H members interested in completing this book do not need to own or ride horses. Members who have horses may also participate in this project. 4-H members should be active members of a 4-H club and complete this project under the supervision of an adult volunteer leader. 4-H members of all ages may complete this project book. This project is intended to be completed in one year. However, there is no time limit on completion. 4-H members may repeat this book as many times as desired. Members are encouraged to complete one Horse Judging Project Record Book for each year that they are actively participating in horse judging. 4-H members must complete Horse Judging Project Record Book Level 1 before they begin work in this book.

This is the first in a series of six lessons that focus on 4-H livestock financial record keeping. It discusses the importance of matching your livestock project animal with your farm’s facilities. This activity will help members learn to set and achieve goals in their animal projects. The discussion about the factors to consider and the questions to ask themselves will help members answer the questions in the project planning section of the record book.

During the summer months of 2017, a team of Virginia 4-H extension agents and a 4-H extension specialist surveyed currently active teens and their parents/guardians to gather insight on how they became involved in 4-H, what keeps them engaged in the program, what they have learned as a result of their participation, how they are utilizing what they have learned, and their familiarity with the variety of opportunities available to teen 4-H members. As a result, 233 teens and 388 parents/guardians responded to the survey, representing all four districts and 71 of our 106 counties and cities in Virginia. The age range of teen respondents was 13-19 years old. This publication highlights the key findings from the study.

In 2013, the Virginia Cooperative Extension’s Leadership, Volunteerism, and Civic Engagement program team identified the need for (1) prepared leaders, (2) more representative civic engagement, and (3) increased capacity to foster volunteerism. Simultaneously, conversations began regarding a need to further develop leadership training and experiences for 4-H and FFA teens that would help them become active and engaged community members.

Acid-base reactions and the concept of pH are critical concepts in chemistry, environmental sciences and Earth science. First, students will present hypotheses of whether the pH will increase or decrease when calcite or pyrite are dissolved in water. Second, in a facilitated activity, students (in groups) will dissolve pyrite and calcite in water and measure the pH after the minerals dissolve. Third, they will hypothesize what happens to the pH when they mix the pyrite and calcite together (in water). Fourth, they will then test their hypotheses by mixing them and measuring pH. Fifth they will discuss if their results support their hypotheses. Last, they will expand what they learned in the experiments to how minerals can be used in water treatment.

Members should also enroll in the Horse Management project and keep an accurate and up-to-date management record. Participate in the riding series is strictly on an elective basis. The riding projects should be closely supervised by a horse project leader. Numerous standard references may be used for completing the diagrams, questions, etc. Members should have the basic equipment for riding and the use of a suitable riding animal.

Virginia’s cool-season grass pastures are highly productive in the spring and fall, but high temperatures and short-term drought stress often limit their growth during summer months. Incorporating warm-season grasses can be a beneficial strategy for meeting feed resources during this period of forage deficit.

While high-quality sod is available outside of the VCIA-certified sod program, the consumer is encouraged to be aware of factors that are important in determining sod quality. Quality sod contains excellent turf varieties with good sod strength (i.e., easy to handle for both harvest and installation) and has no serious insect, weed, or disease problems.

The Shenandoah Valley of Virginia and some other regions produce more manure nutrients than local crops need. This manure has traditionally been applied to row crops and overapplication has led to soil-test phosphorus (P) being well above agronomic optimum in many cases. In 2008, it was estimated that nutrient-management regulations now require that approximately 85 percent of poultry litter be applied off poultry farms, as they do not have sufficient land to beneficially recycle their manure nutrients.

Lean thinking is a process focused on increasing the value added to products and services and the reduction of waste. The term “lean,” coined by Womack during one of his visits to the Japanese carmaker Toyota in the early 1980s (Womack and Jones 2003), has become the universally accepted term for increasing value and reducing waste.

Given the prominence of feeding activity, and the sheer volume of supplemental food dispensed into the environment, it is worthy to examine the impacts of feeding on nature and to improve one’s understanding of the proper care and responsibilities that come with feeding wild birds.

An overview of information to help readers improve knowledge and understanding of human interactions with snakes common to Virginia and methods to avoid conflicts with these often maligned animals.

Lumber is usually dried to a specific moisture content prior to further manufacturing or use. The amount of water in wood is usually expressed as moisture content and can be directly measured or calculated. The moisture content of wood is defined as the ratio of the weight of water in wood to the dry weight of the wood material. While lumber can be air-dried, the humidity in most localities prevents the lumber from reaching the moisture content required for the stability needed for interior use. A dry kiln is required to dry lumber to the necessary final moisture content and does so fairly rapidly. This publication discusses the design and operation of a solar-heated lumber dry kiln that is designed to be inexpensive to construct and simple to operate.

Each year many landowners in Virginia consider Christmas tree farming as an alternative enterprise for their unused open land. The number of growers in the Commonwealth is increasing steadily, and currently Virginia ranks eighth in the nation in Christmas tree production, with about 1.8 million trees harvested in 1990.

This brochure provides information to improve readers’ knowledge and understanding of black bears and discusses various options designed to minimize negative consequences from our interactions with black bears in Virginia.

Aquatic biodiversity is the rich and wonderful variety of plants and animals—from crayfish to catfish, from mussels to mayflies, from tadpoles to trout—that live in watery habitats. It is the number of different native species, or species richness.

When a species goes extinct, all the genetic information carried by individuals of that species is lost forever, never to be reproduced again. Extinction is a terrible waste of life and a loss of potential solutions to future problems such as possible cures to disease and solutions for survival in a changing world.

Natural aquatic habitats include ponds, lakes, rivers, streams, springs, estuaries, bays, and various types of wetlands. Some of these habitats are shallow and others deep, some are cold-water and others warm-water, some are freshwater and others saltwater, and some have high oxygen levels and others little oxygen.

Nearly 300 species of mussels inhabit freshwater rivers, streams, and lakes in the United States. This is the richest diversity of mussels found in the world and an extraordinary natural heritage that needs protection. Because of the lustrous, pearl-like interior of the shells, some of these pearly mussels have important commercial value in the cultured pearl and jewelry industry.

Nearly 800 native fish species in 36 families inhabit the freshwater rivers, streams, and lakes of the United States and Canada. North America has the most diverse temperate freshwater fish fauna in the world.

This is the largest and most ecologically diverse family of freshwater fishes in the world. Minnows are exclusively freshwater, although some species stray into brackish, tidal waters. Over 290 species of minnows occur in North America.

Frogs can be found in all landscapes, from deep under the water to high in trees. There are more than 100 species of frogs in the United States, and many of these are of conservation concern. This publication describes frog biology, diversity, and conservation issues.

Of the more than 700 species of salamanders found worldwide, more than 200 live in North America, and over 40 percent of these are considered to be at risk. Although these secretive creatures are unknown to many people, they are important parts of our natural world and in serious need of our protection. This publication describes salamander biology and conservation concerns.

Six hundred fifty different species of snails are widely distributed across the streams, rivers, and lakes of North America. There are unique species associated with every type of aquatic habitat from the Canadian Arctic to the Everglades of Florida.

The diversity of insects can only be described as amazing. More than half of all known species of living things (microbes, plants, and animals) are insects.

Cherries are grown in many parts of the world, but they have never gained the popularity in North America that they have in Europe and the Middle East. Cherries probably originated in the region between the Caspian and Black Seas, where trees still grow in the wild.

Annual pruning is a critical management practice for producing easily harvested, heavy crops of high quality peaches. However, pruning is not a substitute for other orchard practices such as fertilization, irrigation, and pest control. Pruning practices vary slightly in different regions of the United States, but have changed little in the East during the past 70 years. Although pruning may vary slightly for different varieties and localities, certain general practices should be followed. The successful pruner must understand the principles of plant growth, the natural growth habit of the tree, and how the tree will respond to certain types of pruning cuts. Improper pruning will reduce yield and fruit quality.

Proper training and pruning of trees is a major component of a profitable apple orchard operation. Successful pruning is an art based upon scientific principles of tree growth and physiology and an experienced understanding of tree response to various pruning cuts and practices. Each tree is an individual and should be treated accordingly. Varieties differ in growth characteristics and response to pruning cuts, rootstocks, soil, and growing conditions. It is important that orchard designs, objectives, and goals be clearly defined and that pruning principles are developed accordingly. Mediumto high-density plantings require greater commitment to detailed training and pruning than low-density orchards and should not be attempted unless such a commitment is made.

Growing apples in the home garden can be an enjoyable and rewarding experience, but consistent production of high quality fruit requires knowledge of tree and fruit growth and a willingness to perform certain practices at the appropriate time. Virginia is on the southern fringe of the U. S. apple producing region. Most apple varieties produce the highest quality fruit when night-time temperatures are cool (less than 60°F) at harvest time. Apples grown under warmer conditions tend to be large, soft, poorly colored, and less flavorful than when grown under cooler conditions. Our warm humid summers are also conducive for infection of many diseases. For these reasons, the best Virginia apples are grown at elevations higher than 800 feet above sea level in the western part of the state. However, even apples grown in eastern Virginia usually have quality superior to apples purchased in the supermarkets.

Peach and nectarine are both members of the genus and species Prunus persica, and probably differ by only a single gene for skin pubescence (hairs on the fruit surface). One probably originated as a mutation of the other, but we do not know which came first. The species originated in China and was taken by traders from there into Persia, Greece, Italy, and other temperate areas of Europe. Peach and nectarine varieties may have yellow or white flesh. In Virginia different varieties ripen over a wide range of dates, from early June until mid-September. Varieties also differ in fruit size, susceptibility to some diseases and susceptibility to low winter temperatures, chilling requirements, and fruit disorders such as fruit cracking and split-pit. Descriptions of some of these characteristics are included in the next section of this publication.

This quick guide is a tool to help Unit Coordinators navigate the process of onboarding a new agent in their local office. This resource clarifies the key responsibilities & roles a Unit Coordinator plays in the onboarding process, as well as tips for a successful experience when welcoming a new agent to the local unit office.

The more than 55 million people who live in the mid-Atlantic region of the United States want to purchase processed grain foods such as bread and other dough products made from hard, or bread, wheat. To meet this demand, regional mills import bread wheat, which comes almost exclusively from the Plains states. These imports make up approximately 30 percent of the total grain needed for the region.

Efficient nitrogen (N) fertilization is crucial for economic wheat production and protection of ground and surface waters. Excessive plant-available N produces wheat plants that are susceptible to lodging and disease with resulting decreased yields and increased input costs. The potential for enrichment of ground and surface waters with nitrates also increases with excessive N fertilizer applications.

Corn must have adequate amounts of nitrogen (N) and phosphorus (P) for profitable production. Nitrogen and phosphorus are also the nutrients that produce excessive algae growth in surface waters when concentrations increase above certain critical levels. Profitable and environmentally sensitive corn production requires that N and P be managed in an efficient manner. Economic returns from the use of these nutrients can be maximized, while the potential for surface and groundwater enrichment with N and P can be minimized with the use of appropriate technology. Available technology includes soil testing to evaluate residual soil nutrient supplies, and the use of proper application rates, methods, and timings.

No-tillage corn production has been practiced in Virginia for more than 35 years (Jones et al. 1968), yet many producers have not used no-tillage to its maximum advantage. This publication addresses where no-tillage corn can and should be adopted, and where no-tillage production needs to be modified to reduce production problems associated with continuous use.

Crop production has increased dramatically over the last few decades, much of which has been due to the widespread introduction of chemical fertilizers starting in the mid-1900s. Matching fertilizer application rates to crop needs is an essential component of optimizing crop production. However, different crops in separate fields will require varying rates of the major nutrients – nitrogen (N), phosphate (P2O5), and potassium (potash, K2O) – due to variations in soil types, soil test phosphorus and potassium levels, and nutrient ranges of different crops.

There are many, many factors that could cause either of these statements to be true: year-to-year weather variation, yield potential differences in and between fields, planting date differences, etc. (first published March 2019, last reviewed March 2024)

Soil compaction is a manageable factor that can limit grain or silage yield on many Virginia soils.

Germination of wheat within the grain head before harvest is called pre-harvest sprouting (PHS). Periods of prolonged rainfall and high humidity after the grain has ripened and before it can be harvested can contribute to PHS, which can be thought of as a premature germination.

Modern winter barley cultivars are capable of yields in excess of 170 bu/acre with relatively high test weight. Efficient nitrogen (N) fertilization is crucial for economic barley production and protection of ground and surface waters.

This publication defines watersheds, why they are important to everyone, and how people positively and negatively impact them.

A rain garden is a landscaped area specially designed to collect rainfall and storm-water runoff. The plants and soil in the rain garden clean pollutants from the water as it seeps into the ground and evaporates back into the atmosphere. For a rain garden to work, plants must be selected, installed, and maintained properly.

Humans and plants depend on an adequate supply of clean water for a number of reasons, from producingfood to sustaining life. The average Virginia resident uses 826 gallons of fresh water daily (Virginia Department of Environmental Quality [VADEQ] 2008). In the Commonwealth alone, there are more than one million households that depend on well water, withdrawing more than 50 billion gallons annually (Virginia Department of Health 2008). For groundwater replenishment, we depend largely on recharge (water moving from the surface to groundwater) from infiltration of precipitation through permeable surfaces in the environment — an important part of the natural water cycle (VADEQ 2010).

The value of an attractive landscape to a home’s perceived value has often been stated at 15 percent. Is this figure reliable, and what landscape features do contribute to the value of a home? How does a landscape contractor convince his/her client to spend a significant portion of a home’s construction budget on landscaping, and is this a wise investment? How can a homeowner feel justified by spending thousands of dollars to landscape a newly constructed house? Or, will thousands of dollars worth of landscaping, significantly increase the “curb appeal” of a home for sale? To answer these questions, researchers conducted a seven-state survey of attendees at consumer home and garden shows to determine consumer perspective on how plant size, type, and design sophistication in a landscape affect the perceived value of a home (Behe et al., 2005).

Select only those plants that appear to be free of pests. Check the undersides of the foliage and the junction of leaf and stem for signs of insects or disease. Select plants that look sturdy, clean, and well-potted. Choose plants with healthy foliage. Avoid plants with yellow or chlorotic leaves, brown leaf margins, wilted foliage, spots or blotches, or spindly growth. In addition, avoid those with torn leaves. Plants that have new flower and leaf buds along with young growth are usually of superior quality.

Sheet flow to open space (SOS) is a group of best management practices (BMPs) designed to disperse concentrated runoff to sheet flow into filter strips or a riparian buffer. An SOS reduces runoff volume and associated sediment and nutrients that are carried with it (see figure 1). It is used as a stormwater treatment practice in both urban and rural areas. This practice is often used after another treatment practice to disperse or eliminate runoff. In a few cases, an SOS can be used as a pretreatment to remove small amounts of sediment via a vegetated filter strip — prior to a bioretention device, for example.

Soil restoration (SR) is the technique of enhancing compacted soils to improve their porosity and nutrient retention. It includes biological (worms) and mechanical aeration, mechanical loosening (tilling), planting dense vegetation, and applying soil amendments. Soil amendments involve the spreading and mixing of mature compost into disturbed and compacted urban soils (see Figure 1).

Rainwater harvesting (RWH), also known as rainwater harvesting systems or cisterns, are devices that intercept, divert, store, and release collected roof runoff from rainfall for later use as an alternative water supply (see figure 1). RWH can also be designed to provide runoff reduction benefits. Therefore, it is classified as a best management practice (BMP) for treatment of urban stormwater. Because of its dual purpose and benefit, RWH is often classified as a sustainable urban BMP.

Permeable pavement (PP) is a modified form of asphalt or concrete with a top layer that is pervious to water due to voids intentionally created during mixing. PPs include pervious concrete, porous asphalt, and interlocking concrete pavers. These materials are used as stormwater treatment practices in urban areas. They are used in place of traditionally impervious surfaces to allow infiltration and storage, thus reducing runoff (see figure 1).

Infiltration practices provide temporary surface and/or subsurface storage, allowing infiltration of runoff into soils. In practice, an excavated trench is usually filled with gravel or stone media, where runoff is stored in pore spaces or voids between the stones (see figure 1). These systems can reduce significant quantities of stormwater by enhancing infiltration, as well as provide filtering and adsorption of pollutants within the stone media and soils. Infiltration practices are part of a group of stormwater treatment practices, also known as best management practices (BMPs)

A bioretention cell, or rain garden, is a best management practice (BMP) designed to treat stormwater runoff from roofs, driveways, walkways, or lawns. They are a shallow, landscaped depression that receives and treats polluted stormwater with the goal of discharging water of a quality and quantity similar to that of a forested watershed (figure 1).

Constructed wetlands are a series of ponds with varying depths that treat stormwater using wetland processes. In terms of biological activity, wetlands are extremely productive; and thus constructed wetlands can provide significant water quality treatment to urban runoff. This fact sheet describes these benefits, and provides guidance on their design and limitations.

Wet ponds are ponds designed to retain water through storage. They provide treatment through settling and biological uptake. They can also attenuate peak flows and provide flood and streambank protection. This fact sheet describes wet ponds and their benefits and limitations.

El objetivo de la jardinería intensiva es cosechar la mayor cantidad posible de productos en un espacio limitado. Las huertas más tradicionales constan de largas hileras de hortalizas muy separadas entre sí. Gran parte de la superficie de la huerta está ocupada por el espacio entre las hileras. Una huerta intensiva minimiza el espacio desperdiciado. La práctica de la huerta intensiva no es solo para los que tienen un espacio limitado en el jardín; más bien, una huerta intensiva concentra sus esfuerzos de trabajo para crear un entorno ideal para las plantas, lo que brinda mejores rendimientos.

Home gardeners often use more pesticides per square foot in their gardens than farmers do in the fields, thinking that if a little is good, more will be better. This is a serious mistake and a serious misuse of pesticides. This publication will take the reader through different ways to manage home gardens using integrated pest management strategies, including using cultural and biological control methods for pests. It provides the reader with proven ways to manage pests responsibly by using the least amount of naturally derived or man-made pesticides possible.

Tomatoes are valuable garden plants in that they require relatively little space for large production. Each standard tomato plant, properly cared for, yields 10 to 15 pounds or more of fruit.Diane Relf, Retired Extension Specialist, Horticulture, Virginia Tech Alan McDaniel, Extension Specialist, Horticulture, Virginia Tech Ronald Morse, Former Associate Professor, Horticulture, Virginia Tech Reviewed by John Freeborn, Assistant Master Gardener Coordinator, Horticulture, Virginia Tech

Seeds themselves are a very nutritious form of food because they contain proteins, carbohydrates, vitamins, minerals, and oils that a beginning plant needs to grow. Many of these nutritious components are increased greatly when the seeds are sprouted.

Landscapes are composed of plants that form ceilings, walls, and floors spaces. Groundcovers serve as attractive carpets of foliage that cloak and beautify our landscape “floors” (fig. 1). A groundcover is a low-growing plant species — 3 feet tall or shorter — that spreads to form a relatively dense layer of vegetation. In covering bare soil, groundcovers reduce soil erosion and provide habitat for insects and other animals, along with a host of other positive environmental effects.

What is a shrub? A shrub is generally considered a multi-stem woody plant that is less than 15 feet tall. Of course, this and other plant size categories are definitions contrived by humans to categorize nature. What is the difference between a large shrub and a small tree? In many cases, there is none. A shrub does not become a tree just because it grows higher than 15 feet. Classifying plants into ground cover, shrub, and tree designations are aids to allow us to conveniently classify and describe plants, albeit with a significant amount of ambiguity.

Something is wrong with your plant. What’s the cause? You can begin to determine the cause of the problem by taking on the role of Sherlock Holmes – be a keen observer and ask many questions. Diagnosing plant problems is often a difficult task. There can be many different causes for a given symptom, not all of them related to insects or diseases. The health of a plant may be affected by soil nutrition and texture, weather conditions, quantity of light, other environmental and cultural conditions, and animals, including humans. Complicating this scenario is the fact that any two of the above factors can interact to give rise to a problem. For example, a prolonged period of drought may weaken plants so that they are more susceptible to pests; this is typically observed with boxwoods.

Landscaping is an integral part of our culture and plays an essential role in the quality of our environment, affecting our economic well-being and our physical and psychological health. If we are to keep our communities strong and prosperous, we must take responsibility for our environment.

As a general rule, plant selection and production area in a home garden should be limited to what you can properly care for. It is better to have a small, welltended planting area rather than a large, neglected one. Small fruits offer certain advantages over fruit trees for home culture because small fruits require less space for the amount of fruit produced, and they bear fruit one or two years after planting. Success with small-fruit planting will depend on the attention given to all phases of production, including crop and variety selection, site selection, soil management, fertilization, pruning, and pest management.

It is desirable to locate the fruit planting as close to your home as possible. Where space is limited, fruit trees may be set in almost any location suitable for ornamental plants. Consider the mature size of the tree when designing the planting.

Water makes up 75 to 85 percent of the weight of a healthy grass plant. It is essential for seed germination, tissue formation, plant cooling, food manufacture, and nutrient absorption and transport. A grass plant loses the most water under conditions of high light intensity, high temperature, low relative humidity, and windy conditions.

La fertilización del césped es esencial para la producción de césped de calidad en Virginia. Sin embargo, exceder las tasas recomendadas de aplicación de fertilizante o una frecuencia de aplicación incorrecta puede afectar negativamente la calidad de las aguas superficiales y subterráneas.

Maintenance programs should be developed for trees and shrubs in both residential and commercial landscapes. A good maintenance program includes monitoring and controlling insect and disease problems, suppressing weed competition, and making timely applications of water, mulch, and fertilizer. Tree and shrub fertilization is especially important in urban and suburban areas of Virginia where soils have been altered due to construction. These urban soils tend to be heavily compacted, poorly aerated, poorly drained, and low in organic matter. Even where soils have not been affected, fertilization may be needed as part of a maintenance program to increase plant vigor or to improve root or top growth.

Trees can become a dangerous liability when they are planted near utility lines and their mature size leads to conflicts with the utility lines. Trees can damage utility lines, disrupt power delivery, and create hazardous conditions. Utility companies expend significant resources managing tree conflicts through pruning and removal. Despite the potential for these conflicts, property owners often desire trees near utility lines for amenity and privacy. To prevent recurring conflicts with utility lines, trees with compatible mature size should be planted near utility lines. In this publication are recommendations for minimizing tree conflicts with utility lines along with an extensive list of utility line compatible tree species suitable for landscapes in Virginia and the Mid-Atlantic region.

Increased fuel costs and colder than normal winters make heating costs a significant burden on many greenhouse operations. So, how can growers deal with high energy costs in the greenhouse? This publication covers energy conservation, alternative fuel choices, growing temperatures and production practices.

The fall season is an important transition period of turfgrass growth and development, and the management of your warm- and cool-season grasses at this time of year means a great deal in terms of anticipated success in your lawn the following spring.

Moss is a very simple plant that can out-compete turfgrasses under persistently shaded, moist, acidic soils. This publication details the management strategies that make turfgrass more competitive and the chemical management options that help reduce moss populations. This publication also discusses how to propagate and manage moss as part of a shade landscape when turfgrasses are not an option for a lawn.

When choosing nozzles/droplet sizes for spray applications, applicators must consider both coverage needed and drift potential. As a rule, smaller droplets provide better coverage, but larger droplets are less likely to drift.

Follow these safety tips and maintenance procedures for checking, servicing, and operating compact tractors to extend their life and reduce breakdowns and accidents.

Manure storage is a critical part of a nutrient management plan in a livestock or poultry operation. It's essential to recognize manure as a valuable resource, rich in organic matter and nutrients that can be used as fertilizer or for energy production. While manure can accumulate rapidly, effective management is key to reducing the potential for odors, surface water, and groundwater contamination. This responsible environmental practice not only mitigates these risks but also allows for a strategic approach to managing and using manure. It provides livestock and poultry operations with the flexibility to schedule its use, maximizing the benefits of the resources it contains. Our publication offers guidelines and information for choosing the type of storage and setting them up for farming operations, emphasizing the importance of this responsibility.

Storing manure is a common practice on farms and for those who keep animals. However, a well-designed manure storage facility must also be well-managed to prevent environmental concerns from developing. In most cases, manure storages are used when cold weather, wet conditions, and/or a lack of time do not allow field application. To get the most benefit out of the manure, good management practices and observation of safety practices that minimize manure hazards on the farm are crucial. This publication provides guidelines that stress the importance of good management and safety practices for manure storage to inform the safety and security of a farming operation.

If not managed properly, manure can negatively impact the environment. Therefore, regardless of size, all livestock and poultry operations must handle manure effectively for economic benefits and environmental protection. Media reports often highlight community conflicts arising from livestock and poultry odors, fish kills, and the pollution of surface or groundwater due to poor manure management. These issues have strained relationships between the public and animal agriculture and can be minimized responsibly by managing manure and other agricultural wastes. Effective manure management begins with recognizing its value as a nutrient source for crops and understanding its potential negative effects on air, water, and soil. This publication provides general guidelines for managing livestock and poultry manure. It includes a list of resources with detailed information on best practices for manure management and uses that contribute to good environmental stewardship.

Animal manures are a good source of nitrogen (N) and phosphorus (P) for agricultural crops, but they have an imbalance in their N to P ratio, so that if they are applied to meet crop N needs, then P is overapplied. For many years, manures have been applied to meet crop N needs, which has resulted in some soils containing more P than crops require, leading to environmental concerns. Regulations have been developed to limit P losses from manures and soils high in P by moving manure nutrient management from an N basis to a P basis.

Farm workers can encounter a variety of respiratory problems ranging from temporary discomfort caused by allergic reactions to fatal asphyxiation. However, the risk of contracting serious lung diseases or death can be significantly decreased by using respiratory protection (fig. 1). See the sidebar for a list of farm work that requires respiratory protection.

Farmers account for more than 30 percent of adults dis- abled by respiratory illness. Yet, a large percentage of farmers are nonsmokers. If smoking is not to blame for these ailments, then what is? The answer is farmer’s lung.

Private water sources such as wells and springs are not regulated by the U.S. Environmental Protection Agency (EPA). Although private well construction regulations exist in Virginia, private water supply owners are responsible for providing maintenance for their water systems, monitoring water quality, and taking the appropriate steps to address problems, should they arise.

Sodium and chloride, which together compose common table salt, often occur naturally in groundwater as it dissolves minerals underground. Higher levels of sodium and chloride in household water, however, often come from manmade sources such as road salt, industrial wastes, sewage, fertilizers, or water softeners. In coastal areas, sodium and chloride can also enter groundwater via salt water intrusion into fresh water aquifers. In high enough concentrations, salt water intrusion can render groundwater unsuitable for drinking, cooking, or irrigating.

Shock chlorination is a process of disinfecting a private water supply and plumbing system by circulating a concentrated chlorine solution throughout the system.

Micro-irrigation systems can deliver water and nutrient in precise amounts and at controlled frequencies directly to the plant’s root zone. With micro-irrigation systems an extensive network of pipe is used to distribute water to emitters that discharge it in droplets, small steams, or through mini-sprayers. The major cause of failure in micro-irrigation systems is emitter plugging. Emitter plugging can severely degrade irrigation system performance and application uniformity. The goal of this document is to provide information on common water quality problems that can lead to emitter clogging, and how these problems can be addressed through water treatment and system maintenance. This should help producers identify, prevent, diagnose, and address clogging problems in their micro-irrigation systems.

Four species of aphids attack small grains in Virginia - greenbug, corn leaf aphid, bird cherry-oat aphid, and English grain aphid.

Adult thrips are small, pale-yellow insects (occasionally black) with elongated bodies, and fringed wings. Their life cycle consists of an egg, nymph, pre-pupa, pupa and an adult. The exact time required for thrips to complete their life cycle varies with species, temperature and the host plant. Western flower thrips complete their life cycle, from egg to adult, in approximately 10 days at 80° F. Adults insert eggs in leaf tissue which hatch in approximately three days. Nymphs feed for four to five days and then drop from the plant to pupate in the soil. Adults emerge after two days of pupation and begin feeding.

This book provides forms for many of the categories of expenses, receipts, labor, and financial summaries needed by most agricultural related businesses using cash accounting methods. Column headings are included for major items with some columns remaining blank for your own headings.

The most effective form of plant disease control in the landscape is prevention. Disease prevention can be as simple as choosing the right plant for the right place at planting time. This fact sheet was developed as a guide to shrubs that generally experience few problems in Virginia landscapes. Using these species for new plantings should help you avoid troublesome disease and insect problems in your landscape.

La forma más eficaz de controlar las enfermedades de los cultivos en nuestro jardín es la prevención. La prevención de enfermedades puede ser tan sencilla como elegir el cultivo adecuado para el lugar adecuado al momento de cultivar. Esta hoja informativa fue desarrollada como una guía de los arbustos que generalmente experimentan pocos problemas en los paisajes de Virginia. El uso de estas especies para las nuevas plantaciones debería ayudarle a evitar problemas de enfermedades e insectos en su jardín.

Many of the tree species commonly planted in Virginia landscapes suffer from disease problems. Although some diseases can be cured, most must be controlled on a preventative basis. The best option for new plantings is to choose species that have a low risk of developing disease. Listed below, in alphabetical order, are some choices of problem-free trees for Virginia landscapes.

Anthracnose is a generic term for a disease that occurs on many ornamental and forest trees. A number of different fungi cause anthracnose on various hosts. It occurs most commonly and severely on sycamore, white oak, elm, dogwood, and maple. Other host plants that usually show only minor symptoms of anthracnose include linden (basswood), tulip tree, hickory, birch, and walnut. Anthracnose fungi may be host-specific, as in the case of sycamore anthracnose, which infects only sycamore and not other tree species. Anthracnose fungi have similar life cycles, but require slightly different moisture and temperature conditions for infection.

Rose rosette disease (RRD) is a serious disease problem of cultivated roses, and over the past two decades RRD has become the most important rose disease in North America. RRD is caused by Rose rosette virus (RRV). RRD leads to stunting, decline and death of roses, yet there are no easy, economical or particularly effective management tactics for RRD. Currently, the major rose cultivars available to growers are susceptible to RRD.

Angular leaf spot of cucurbits is caused by the bacterium Pseudomonas syringae pv. lachrymans. The bacterium can attack a wide range of cucurbits including watermelon, melon, squash, cucumber, zucchini, and pumpkin.

Brown rot is one of the most destructive diseases of peach and nectarine in Virginia, and also occurs on other stone fruits such as apricot, cherry, and plum. When environmental conditions favor this disease, crop loss can be devastating.

Pesticide use affects the quality of human health, the environment, and nontarget organisms in the ecosystem. Therefore, any pesticide application warrants a careful assessment of the expected benefits and risks. Too often, however, homeowners use pesticides inappropriately or without careful consideration of alternatives. This fact sheet outlines general pest control tactics that can easily be implemented for home lawns and gardens, along with other information that home owners can use to make sound pest management decisions. The intent is to ensure that homeowners are aware of alternative control tactics and pesticide characteristics, and that pesticides are used properly and only when necessary

Most trees and shrubs are susceptible to dieback and cankers caused by several species of the fungal genus Botryosphaeria. Botryosphaeria fungi are typically opportunistic pathogens. Opportunistic pathogens only cause disease on plants that are stressed. Therefore, avoiding plant stress, which predisposes plant tissue to infection and colonization by this fungal group, is the best strategy to prevent Botryosphaeria disease problems.

Acid soil limits crop yields on many Virginia farms. This soil acidity can be directly toxic to plants, but more often it reduces the plants' efficiency at nutrient utilization.

Your Soil Test Report and related Soil Test Notes referred to on a report will help you assess your plant’s need for fertilizer and lime.

Most Virginia soils are acidic and require lime applications at three- to five-year intervals. Maintaining the correct soil pH has several benefits, such as encouraging healthy root development and making sure nutrients in the soil are available to the plant. For example, low pH can cause aluminum toxicity and can decrease phosphorus availability.

The only way to accurately predict lime and fertilizer needs in forages is through soil testing, as explained in “Soil Test Note No. 1 – Explanation of Soil Tests,” Virginia Cooperative Extension publication 452-701. See www.soiltest.vt.edu.

The guide contains information on pesticides used in orchards, with a seasonal treatment of when and how these materials should be employed. Efficacy information toward major fruit pests as well as beneficial species is included. The guide is black and white, but with a color photograph for the cover. It is spiral bound.

This guide lists vegetable varieties that are available and are adapted to the mid-Atlantic region, gives an overview of cultural practices, and list chemicals recommended to manage pests, diseases and weeds in vegetable crops. New varieties of vegetables are constantly being developed throughout the world. While all efforts are made to have comprehensive lists, not all varieties that are adapted will be listed.

Christmas tree production can be an excellent use for reclaimed mined lands in Virginia. Most species do quite well on mine soils because they are more tolerant of infertile and droughty conditions than agricultural or horticultural crops, yet they do respond to active management. Christmas trees can be harvested within seven to 10 years, while timber crops take much longer to mature. For the person with time to invest, Christmas trees can be an ideal way to put small parcels of reclaimed mined lands to profitable use. Individual growers can conveniently maintain up to 5 acres of trees in their spare time.

This publication describes procedures for revegetating surface coal mine reclamation sites with grasses and herbaceous legumes.

This publication describes procedures for re-establishing native forest trees on surface coal mine reclamation sites in southwestern Virginia and elsewhere in Appalachia.

This publication describes procedures for preparing mined lands to serve industrial sites by ensuring adequate geotechnical stability for that purpose, and for converting mined lands that were reclaimed for other purposes to industrial uses.

This publication describes procedures for treating and renovating water quality of acid-mine drainage discharges using "passive treatment" technologies such as constructed wetlands.

This publication describes plant communities occurring on mine sites that were reclaimed during different eras, and using different reclamation methods.

The development of Southwest Virginia’s coal mining region is limited by a lack of building sites. Much of the land in this region consists of steep slopes with shallow soils that are poorly suited to residential development. In recent years, widespread surface coal mining has created landforms that are favorably located and configured to support residential housing. However, because such sites are commonly located beyond the extent of public sewers, developing them requires a means for on-site wastewater treatment and dispersal. This publication is written for homeowners, homebuilders, land developers, public officials, and others who may have an interest in building residential housing or other types of development on mined lands that are not accessible to public sewers.

This publication describes procedures for converting reclaimed mined lands that are unmanaged into productive forest ecosystems with native trees as dominant vegetation.

This publication provides an overview of the study of mammals in Virginia. It includes an up-to-date listing of mammals found in Virginia and information on the biology and natural history of mammals. The intended audience is Virginia Master Naturalist volunteers and others seeking to gain a basic understanding of this topic.

An Extension Leadership Council (ELC) is a key ingredient for success in developing, implementing, and evaluating Extension programs that serve the local community. This publication offers practical guidelines and resources for successfully engaging a local ELC. Contents include council responsibilities, criteria for membership, a sample position description, focus topics for regular meetings, and a template for meeting agendas. It is intended as a resource for both volunteers and Extension personnel.

Marine finfish production is a rapidly expanding field, both in research and industrial aquaculture. A driving force behind this growth is the inherently high value placed upon marine finfish products in the marketplace.

Aquaculture continues to be the fastest growing sector of food production world-wide. The Virginia aquaculture industry produces a variety of different foodfish, baitfish, shellfish, and ornamental species. Likewise, a variety of different production methods are implemented across the state, including pond production and indoor, intensive recirculating aquaculture systems (RAS). Continued expansion of aquaculture in the state, as well as across the region and country, demands attention to both environmental and economic sustainability.

This document provides the background, rationale, and detailed production protocols for all stages of high-quality Artemia culture.

Amyloodinium ocellatum (abbr. A.ocellatum) is a marine dinoflagellate. While most marine dinoflagellates (small protozoan organisms) exist as free living members of the planktonic community, some such as A. ocellatum live at least a portion of their life cycle as parasitic organisms.

Trichodina spp. are a group of dorsal-ventrally flattened oval ciliated protozoan parasites of marine and freshwater species of finfish.

There are many factors to consider before starting a new farm enterprise. Financial management is an important component in the startup and decision-making processes for beginning farmers. The purpose of this series of publications is to inform Virginia agribusiness owners and managers about farm financial risk management tools, techniques, and resources available to help them prepare and use a financial systems approach for their operations.

Vegetable soybean [Glycine max (L.) Merril] is a type of food-grade soybean originating from East Asia. Edamame, pronounced “eh-dah-mah-may,” is an immature soybean, harvested between growth stages R6 and R7 when pods are about 85%-90% filled and bright green. This study is the first to present production and economic considerations for fresh market edamame in the state of Virginia and can be useful to growers considering its production.

Grain and soybean production is a critical component of Virginia agriculture — the state’s No. 1 industry (VDACS 2013). Virginia’s farmers produced more than half a billion bushels of grain and soybeans over the span of 2006 to 2012 (USDA-NASS 2013b)1. The objectives of this publication are to characterize the market for grain production and storage in Virginia.

Did you know that farmers who sell unprocessed foods to retail outlets typically receive just 11.6 cents of each dollar the consumer spends on food? The remaining amount is allocated to industry groups such as food processors, packaging and transportation, retail trade, food services, energy, finance and insurance, and legal services.

The history of Virginia fence law began not long after the first English settlement was founded in 1607. Virginia fence law has transcended from requiring landowners to fence in their livestock beginning in 1631, to requiring landowners to fence-out unwanted livestock beginning in 1643, to the modern-day rule granting localities the authority to return to a fence-in rule of law. This overview sets forth the history of Virginia fence law and explains the modern-day rule of law, including what constitutes a lawful fence and when you need one.

This report succeeds the Agricultural Land Sales in Virginia report analyzing agricultural land sales in the Commonwealth of Virginia from 2010 – 2018 (the “2018 Report”). Similar to its predecessor, this report provides insight into agricultural land sales in the Commonwealth from 2019 through 2020 and summarizes the averages of market-based agricultural land transactions at the multicounty district and statewide levels. The highest growth rate was observed in the Northern ASD district. Statewide, the market-based estimates of farmland averaged $5,533 per acre, a 14% increase from 2019 to 2020.

With funding from the USDA Beginning Farmer and Rancher Development Program in fall 2010, the Virginia Beginning Farmer and Rancher Coalition Program aims to meet the expressed needs of Virginia’s beginning farmers and support the development of social networks through which they can gain vital skills, information, technical assistance, and business capacity for long-term agricultural viability (see www.vabeginningfarmer.org).

We all depend on and benefit from the woods every day, whether we know it or not. The trees, shrubs, plants, animals, and soil that make up your woods provide you, your neighbors, and your region with a host of environmental, social, and economic benefits.

Research into the attitudes and actions of private forest landowners shows that although very few own their forestland for the purpose of producing timber, most will sell timber at least once in their lifetimes. Private forest landowners sell timber for a variety of reasons that range from purely financial to solely for management purposes. Often landowners do not consider selling timber until they have an immediate need for cash. Other times the landowner has planned an immediate commercial thinning with a full timber harvest scheduled in 10 years. Whatever the reason(s) for a timber sale, careful consideration of objectives is paramount.

Timber harvesting is a valuable tool to help forest landowners realize certain financial and land management goals. Following are some suggestions to consider before selling timber.

The mighty American chestnut tree (Castanea dentata [Marsh], Borkh.) was once a dominant figure in hardwood forests throughout the eastern United States. An iconic source of food, chestnuts were sold by the ton every year, until the chestnut blight nearly brought this tree crop to extinction in the early to mid-20th century.

This publication provides information on how to identify the wood of several species common to Virginia using a hand-magnifying lens. It includes a wood identification key for some common Virginia species, a list of key species characteristics, and a list of companies that sell wood identification sample sets.

Northern fowl mites (Ornithonyssus sylviarum) are one of the more common ectoparasites (external parasites) that can be present in a poultry flock. This publication discusses detection, prevention, and treatment options

Footpad dermatitis refers to a lesion on the footpad and/or toes, characterized by black, necrotic skin and inflammation. This is a widespread condition that can occur in any poultry flock, from mini scale backyard birds to large-scale commercial settings. This publication covers information about the prevalence, causes, methods to keep track, and some potential remedies.

Predation is a common risk for poultry that are allowed to roam freely outdoors (Fig. 1). Predator types may differ depending on the region. Therefore, this article may not cover all possible predators for a specific geographical region. This article provides an overview of potential flock predators, how to identify the predator, and approaches to avoid predation in your free-range poultry flock.

This project will be used to disseminate current thoughts and understand the invasive species of Asian Longhorned Tick (ALT) and the spread of Theileria. The Asian Longhorned Tick is a new invasive species that was first found in the US in 2017 and has since spread to 19 states from the Atlantic Coast to the Southeastern region of the US. The ALT is credited with the widespread of Theileria. Theileria is a blood protozoa parasite that has had a negative impact on cattle producers across the state. This article is what we currently understand about the ALT and the spread of Theileria.

Domesticated chickens, like their ancestor the Jungle Fowl, will range outdoors when given the opportunity, especially when given shelter or natural overhead cover from bushes and trees. Poultry flocks that get the opportunity to range outdoors can benefit in terms of health and behavioral opportunities. However, many factors impact ranging behavior, including shelters, weather, time of day, early life experiences, fear, group size and genetics. Here we focus on one component that could stimulate poultry to use the range more, which is to provide natural vegetation other than grass.

A highly-pathogenic strain of Avian influenza, or bird flu is currently present in the United States. The outbreak started in early 2022 and continues. So far, the disease has infected both commercial and backyard poultry flocks resulting in the loss of over 90 million birds. It was recently detected in other livestock species, such as dairy cattle, and wildlife. It can transmit to humans. Biosecurity measures could prevent transmission of this disease.

Consumers enjoy eating a variety of seafood and can find many choices of fresh as well as frozen seafood in the refrigerated and freezer cases of grocery stores.Abigail Villalba, Extension Specialist, Virginia Seafood Agricultural Research and Extension Center Michael Jahncke, Professor, Food Science and Technology, and Director, Virginia Seafood Agricultural Research and Extension Center Michael Schwarz, Extension Specialist, Virginia Seafood Agricultural Research and Extension Center David Kuhn, Assistant Professor, Food Science and Technology, Virginia Tech Alisha Farris, Extension Specialist, Human Nutrition, Foods, and Exercise, Virginia Tech

According to the Centers for Disease Control and Prevention, as many as 11 million Americans have food allergies. A food allergy can trigger symptoms ranging from a tingling mouth, swelling of the tongue and throat, hives, and abdominal cramps to anaphylaxis and — in severe cases — death (CDC 2012). Consumers with known allergies must read labels to identify allergenic foods or ingredients on packaged products so they can more easily avoid them.

This publication presents and discusses concepts that are fundamental to understanding soil, water, and plant relationships and the soil water balance. Knowledge about soil water relationships can inform the decision-making process in agricultural operations or natural resource management, such as determining what crops to plant, when to plant them, and when various management practices should be scheduled. Understanding these concepts is useful for addressing both agronomic and policy issues related to agricultural water management.

The objectives of this publication are (1) to outline some climate-related challenges facing agriculture, (2) to address challenges in communicating climate change issues, and (3) to propose best practices when attempting to communicate climate change issues to agricultural stakeholders. Extension educators and agricultural service providers can use the information presented here to develop outreach and educational programs focused on the impacts of climate change, the effects of climate change on agricultural production, and the best ways to motivate behavior change.

Virginia usually receives ample rainfall to support agriculture, but droughts in 2002, 2007, and 2010 led to severe problems for farms in many regions. Using groundwater for irrigation can help manage drought risks on farms without access to ponds or streams. However, installing groundwater wells can be expensive and time-consuming. The amount of water obtained from wells can vary in different regions of the state. This bulletin is intended to provide agricultural producers with information on technical and regulatory issues related to irrigating with groundwater.

This publication highlights recent advances in adapting denitrifying bioreactors developed in the Midwest to the Mid-Atlantic region. Denitrifying bioreactors are edge-of-field management practices that harness the activity of soil bacteria to remove excess nitrogen from drainage waters. Agricultural drainage is a significant source of nutrients to the Chesapeake Bay and important to manage. Although challenges remain with respect to adapting designs to treat ditch drainage, denitrifying bioreactors hold promise to yield water quality improvements in the Chesapeake Bay watershed.

Row crop agriculture in Virginia and other Eastern states is largely rainfed, but there is increasing interest in irrigation as a way to manage dry periods and weather variability. However, irrigation systems require substantial installation and operating costs, and it can be very difficult to determine if yield improvements will be sufficient to justify these costs. This publication provides an overview on the Irrigation Financial Estimator Tool, which was recently developed to help row crop producers estimate financial aspects of supplemental irrigation. The tool estimates installation and operating costs, as well as revenues from improved yields, using user-supplied information and historic data on weather and prices for crops and fuel. It accounts for uncertainty in these estimates by presenting a range of values for each cost.

Irrigation scheduling is the process of deciding when and how much irrigation to apply to a field. Applying too little irrigation water can cause crop losses and yield reduction, but applying too much water can waste money, fertilizer, and labor, and can even decrease yields in some cases. The goal of this bulletin is to provide information that can help irrigators schedule irrigation using the checkbook method. It describes some of the benefits of irrigation scheduling and general factors that influence the amount and timing of irrigation needs. It then describes the data needed for checkbook irrigation scheduling and how to get this data, the calculations involved, and software/apps that can be used to help with these calculations.

Many hand tools such as shovels, hoes, rakes, trimmers, and pruners are widely used in lawn care and landscaping. While these tools appear to be harmless, when used improperly, they can cause injuries that sometimes require medical treatment. In 2006, the U.S. Bureau of Labor Statistics reported nearly 205,000 cases of injuries and/or illnesses resulting from the use of hand tools.

In addition to mowers and hand tools, several powered hand tools such as string trimmers, lawn edgers, hedge trimmers, and leaf blowers are widely used in landscaping work. These machines can be dangerous if they are used improperly. A past study has shown that string trimmers and edgers alone cause more than 4,600 injuries that require emergency room treatment each year. About one-third of these cases are eye injuries.

Rotary mowers are very useful types of equipment, but they are dangerous, with the potential to cause serious injuries. Their blades rotate at a high speed of 2,000 to 4,000 revolutions per minute. The equivalent speed at the blade tip or the speed of debris thrown by the mower blade may range from 100 to 200 miles per hour. In order to prevent serious injuries, the operator should be able to disengage the blade and turn the engine off quickly.

Most tractors used in landscaping, lawn care, and golf course maintenance are compact tractors in the 20 to 40 horsepower range. Although these tractors are considerably smaller than farm tractors, they are susceptible to the same types of accidents, with potential for serious injuries or deaths. Causes for such serious accidents are often the same in both cases, and therefore, the steps to take to avoid the accidents are the same.

Utility-type vehicles are popular, multipurpose equipment used for different applications in the lawn care industry. Their hauling capability and versatility have increased their popularity, and they are widely used in rural, suburban, and urban settings for a variety of lawn care, agricultural, construction, and industrial applications.

The goal of this training guide is to reduce the number of accidents and related injuries among the youth workers in the green industry by making workplaces safer. This guide is primarily for employers or supervisors of youth workers in the green industry. In addition to familiarizing the employers/supervisors with the regulations associated with hiring youth workers, the guide discusses the steps they can take to make their work environments safer. It also covers the responsibilities of guardians and youth workers for making workplaces safer.

Mowing lawns continues to be one of the most popular summer job opportunities for youth given the affordable cost and ease in operation of most rotary mowers. However, easy access and widespread use of mowers often creates a false sense of security among the users of these machines. Data from a seven-year period (1996-2003) showed the highest rate of hospitalization from lawn mower injuries was for youth workers ages 15 to 19. The Consumer Product Safety Commission reported that more than 37,000 riding mower injuries occurred from 2003 through 2005 alone. During the same period, there were 95 fatalities due to riding mower tip-over. The purpose of this training guide is to reduce the number of mower accidents and injuries by familiarizing young workers with rotary mowers and their safe operation.

Tractors are versatile equipment used in a variety of jobs ranging from hauling goods to lawn care to agriculture. While they are extremely versatile, they can be very dangerous unless they are used with care following safe practices. Accidents resulting in fatalities and severe injuries are very common during tractor use. The National Safety Council estimated that approximately 36 percent of all the agricultural fatalities in 1997 involved a tractor. Published data also show that farm accidents cause more than 100 deaths and about 2,600 serious injuries among children annually. Tractors account for about 41 percent of the accidental deaths among children under 15 years of age. In spite of these convincing data, a large number of operators continue to follow unsafe practices that can cause serious accidents.

Utility type vehicles (UTVs) are popular equipment used in a variety of settings, including the lawn care industry. Their hauling capacity and versatility have increased their popularity, and they are widely used in rural, suburban, and urban settings for a variety of lawn care, agricultural, construction, and industrial applications. Considering that UTVs are widely used in the green industry, it is extremely important that young workers in the industry become familiar with the safe operation of UTVs. The purpose of this training guide is to familiarize young workers with the safe use of UTVs.

In addition to rotary mowers, many powered hand tools such as string trimmers, lawn edgers, hedge trimmers, and leaf blowers are widely used in lawn care. While these devices are very useful in making jobs easier and more efficient, they can be dangerous if used without proper training and care. In 1989 the U.S. Consumer Product Safety Commission reported that power lawn trimmers and edgers alone have caused about 4,600 injuries annually that required medical attention. About one-third of these were eye-related.

Many hand tools such as rakes, shovels, and pruners are used widely in lawn care operations. While these non-powered tools are not known to cause major injuries, they have the potential for injuries that may require absence from work and/or medical assistance when they are used improperly.

Denitrifying bioreactors (DNBRs) are an alternative best management practice (BMP) that can reduce the amount of nitrogen reaching surface waters. DNBRs function by supporting soil microorganisms that are capable of denitrification in a favorable environment.

Pesticide sprays consist of at least 95% water. Water quality plays an important role in pesticide performance. The following issues may indicate a compatibility problem with pesticides and spray water quality: - Pesticide does not work at labeled rates; - Difficulty mixing sprays or clogging of nozzles; - Inconsistent pest control observed in fields or plots; - Pests seem resistant to a new pesticide active ingredient, or - Crops are lower quality or lower yielding. Understanding how water quality characteristics such as pH, water hardness, turbidity, and total suspended solids affect the adsorption and persistence (half-life, storage time) of a pesticide can help pesticide applicators reduce or eliminate compatibility issues and improve pesticide effectiveness

Mixing two or more pesticide products can allow for the treatment of several pests at the same time, improve pesticide performance, and ultimately saving time and money. However, physical and chemical tank mix incompatibilities can occur when combining two or more pesticides. Physical incompatibility is the failure of pesticide products to stay uniformly mixed and can result in layering, products settling out of solution, or clumping. A chemical incompatibility is the result of a chemical reaction between pesticide products. A chemical incompatibility is less visible and can be harder to detect. This publication focuses on basic factors that influence product compatibility (agitation speed and method, water temperature, mixing order, carrier type, and chemical formulations) and summarizes best mixing practices to address these factors.

Spray water problems may arise due to water quality and management decisions. Certain aspects of water quality can reduce the efficacy of the pesticide as well as affect how the pesticide interacts with the plant surface or targets pests. Evaluating and testing spray water chemistry can help identify water quality problems that might otherwise be overlooked. This publication will examine possible solutions to spray water problems, including the use of adjuvants and other additives to enhance pesticide performance.

Forest inventory (timber cruising) is a common activity used to quantify the resource. The data collected are used to form statistical estimates of a variety of important characteristics; however, these estimates are uncertain due to sampling. Confidence intervals are a relatively simple statistical tool that can help managers quantify this uncertainly and make more informed management decisions. This article explains confidence intervals, provides an example of their use, and discusses their management implications.

Because of the coyote's versatility, adaptability, and its current wide distribution throughout Virginia, the likelihood of encountering a coyote is real. Thus, residents of the Commonwealth should become more aware and informed about the traits and behaviors of this species to avoid undesirable interactions. This publication provides basic information about the coyote, its expected and normal behaviors and other life history aspects, and suggestions on how to minimize or avoid problems that can arise from our interactions with this fascinating creature.

Virginia Master Naturalist volunteers are well-positioned to help more people of all ages and backgrounds to have regularly occurring, meaningful experiences in nature that meet their personal interests and needs. As volunteer educators, they may provide interpretive talks, lead interpretive walks, develop interpretive brochures and signage, and give formal presentations. The foundation for all of these forms of education includes knowing one's audience; planning topics, themes, goals, and objectives; background research and preparation; communicating clearly; and evaluating. This publication describes these key concepts and provides step-by-step guidelines for planning interpretive programs and other educational interactions.

Woodland owners increasingly hear about opportunities to earn income by participating in emerging forest carbon markets. This publication provides an overview of these markets and introduces the carbon credit programs operating in Virginia. This information is intended to help Virginia’s woodland owners decide if taking part in a forest carbon credit program is a good fit for their management objectives.

Estimates of the economic damage caused by meadow voles (Microtus pennsylvanicus) and woodland voles (formerly pine vole) (Microtus pinetorum) exceed $5 million annually to agricultural commodities (e.g., vegetable and grain crops, fruit orchards, flowering bulb production), nurseries, Christmas tree plantations, residential landscape plantings, and woodland parcels recently replanted with pine seedlings. This publication focuses on methods to resolve problems associated with the injurious meadow and woodland voles.

Regression techniques are widely used in forestry to predict difficult-to-measure tree characteristics. Despite their widespread applications, there is often a hesitancy to use them due to a perceived complexity. Further, these techniques are often misused. This extension publication introduces linear regression in an approachable, applied manner. The goal is that interested landowners and forestry professionals will consider using regression in their work and will have the knowledge to better critique published equations.

Silvopastures intentionally integrate trees with forage and livestock production in a rotational grazing system. These systems have the potential to improve animal comfort, increase farm resource use efficiency, boost income, and mitigate environmental costs.

Silvopastures — integrated tree-forage-livestock production systems — have the potential to boost farm resource use and income. These systems take advantage of the beneficial interactions among system components, add biodiversity, and increase animal comfort. The intentional and careful combining of trees and livestock in time and space can yield both short-and long-term returns and have positive environmental outcomes.

Phosphorus is a naturally occurring element that is one of 16 elements essential for plant growth and animal health. Research has documented that applying phosphorus in fertilizers or manure increases crop growth and yield on soils that are below critical agronomic levels, as measured during routine soil testing. Although the economic benefits of phosphorus fertilization on crop production are well-documented, too much of a good thing can be detrimental to the environment. Excessive soil phosphorus is a potential threat to water quality.

Dairy farmers are usually subject to net income fluctuations due to volatility in both milk and feed prices. Risk management tools, such as hedging milk prices in the futures market, may be used to protect dairy farmers against milk price volatility. Alternatively, dairy farmers selling milk in Virginia can buy Virginia milk commission base (MCB) to obtain higher milk prices and, therefore, sustain or increase net cash flows.

Typically, feed costs are directly related to milk production, so the more you feed, the more you produce. However, milk production is not necessarily related to profitability. Production-oriented management, which focuses on maximizing outputs (i.e., milk yield) through increased utilization of inputs (i.e., feed), does not necessarily ensure the dairy business will be profitable.

The bed bug species that is infesting homes today are the descendants of cave dwelling bugs that originally fed on bat blood. When humans began living in the caves (100,000 to 35,000 years ago, depending on the source), the bugs began feeding on humans. Later, when humans moved out of the caves and started their agricultural civilizations, the bugs moved with them. Since that time, humans have carried bed bugs all over the world.

Cold plasma is a new food processing technology that can effectively reduce pathogens on a variety of food products. After conducting a nationwide survey with consumers, it was found that the term 'Cold Plasma' was perceived negatively by the consumer.

The Produce Safety Rule (PSR) is one of the seven major food safety regulations that are authorized by the Food Safety Modernization Act (FSMA). The PSR standards (subpart F) describe the minimum requirements for treated and untreated biological soil amendments of animal origin and human waste for reducing public health risk and the risk of contaminating covered produce. The PSR standards include requirements for determining if biological soil amendments of animal origin are treated or untreated and how to handle them. The standards also address the use of human waste, treatment of the biological soil amendments, application methods and intervals, and recordkeeping.

The Food Safety Modernization act (FSMA) Produce Safety Rule (PSR) covers packinghouse activities in several subparts of the regulation. These include subpart D - worker health and hygiene, subpart E - agricultural water, subpart K - growing, harvesting, packing, and holding activities, and subpart L - equipment, tools, buildings, and sanitation. Applying the practices required by the PSR to packing houses is an important element to ensure the safety of fruits and vegetables.

Microwaves are one of the most common food processing technologies used. Most consumers are familiar with using a microwave in their home kitchen, however, do not realized that some of the food that they purchase has been processed using microwave technology. This publication was created to provide simple, easy to understand science based information on what this technology is and how it can make foods safer. The goal is for the public to be more aware and accepting of various technologies that are used to make our food supply safe.

Postharvest handling of potatoes on the Eastern Shore of Virginia (ESV) regularly includes the use of flumes, dump tanks, and spray washers. Water used in flumes and dump tanks is often re-circulated to conserve water and energy. Soil, plant matter, and disease-causing pathogens can potentially accumulate in water during bin dumping and flume recirculation.

Creating and maintaining community and school gardens has been identified as an effective strategy to increase healthy food awareness and consumption. Unfortunately, fresh fruits and vegetables have been linked to hundreds of outbreaks of foodborne illness in the U.S. since 1990. This document outlines the recommended agricultural practices for food safety in gardens.

Colorectal cancer is the fourth most commonly diagnosed cancer in the U.S. Despite that, colorectal cancer is preventable, and we have good screening tests to detect this cancer early.

"Low Tunnels in Vegetable Crops: Beyond Season Extension" is a comprehensive document that delves into the multifaceted benefits of micro tunnels in vegetable cultivation, encompassing not only extended growing seasons but also improved yield, pest management, and resource efficiency, making it an essential resource for modern sustainable farming.

This publication features small, medium, and large flowering shrubs (five of each category) with photos. All photos are by the author. There are at least eight shrubs from each category noted in a table (without photos) at the end of this publication. All shrubs — featured or in the table — are landscape worthy and are especially suited to landscapes in Virginia and the Mid-Atlantic States.

Herbicides that are usually associated with contamination of straw/hay, turf clippings, manure, and composts are growth regulator herbicides or synthetic auxins, a group of herbicides that mimics plant hormones and regulates growth. These herbicides are labeled for control of broadleaf weeds in grass crops, such as pastures and corn; in turfgrass, including lawns, golf courses, parks, and highway turf; and in noncrop areas. Vegetable and fruit crops, as well as broadleaf ornamentals can inadvertently be injured by these chemicals through drift of spray droplets, volatilization, and spray tank contamination or by residues in straw, manure, turf clippings, or compost. Diagnosing the specific herbicide responsible for the plant damage can be difficult. This publication focuses on damage caused by herbicide residues.

Fescue is the predominant forage in Virginia because of it is productive, high-quality forage across most of the state. However, the plant's positive agronomic traits are offset by toxins in the plant that cause significant reduction in animal performance and welfare. This article discusses fescue, the sources of toxins and their impacts, and provides some management strategies for addressing toxicosis.

Irrigation management of nursery crops grown in containers can be difficult since many factors influence the decision of when and how much to irrigate. These factors include weather, substrate properties, crop water use, crop canopy, irrigation system performance, and water quality. In making the decision to irrigate, many growers rely on their experience with the crop and the substrate in which it is grown, current weather conditions, or forecasts.

Chemical fruit thinning is commonly practiced in commercial apple orchards to manage and regulate the number of fruit per tree (crop load), which improves fruit quality and production. In this management practice, growers typically apply several sprays of chemical thinners to orchard blocks in the spring when the fruit is small and just beginning to develop. These thinning spray applications result in the abscission, or detachment, of some of the fruit. This intentional fruit abscission or shedding is commonly referred to as “thinning.”

An overview of buffers, one of the most common residential stormwater management practices.

Since 2015, Extension specialists from Virginia Tech (VT) have visited and collected plant and soil samples from several large areas of dying great rhododendron (Rhododendron maximum) in Virginia’s mountainous regions. In 2016 VT specialists met with Virginia Department of Forestry, US Forest Service personnel, and other experts to revisit some of these sites. No consistent cause of this mortality has yet been identified. It is possible that a variety of factors are stressing the rhododendrons in these areas to a point where opportunistic pathogens or insects can successfully attack and kill them. The following information summarizes our observations and diagnostic results from four separate great rhododendron mortality sites in Virginia. This information is not equivalent to a research study, which would also include samples taken from healthy great rhododendron for comparison; however, we are confident that we have ruled out two diseases that are frequently mentioned both online and anecdotally as a cause of this mortality, specifically Phytophthora root rot and Botryosphaeria dieback.

Endophyte-infected tall fescue is the dominant forages in Virginia. As such, it is imperative to manage this important forage resource wisely. Ergot alkaloids produced by fescue’s fungal endophyte create challenges to accomplishing this. Tests for endophyte presence and alkaloid levels are important management tools that producers can use to minimize alkaloid consumption and the negative impacts of on animal performance. Consistent testing methods are important for adequately assessing alkaloid levels and for making comparisons among pastures over time. These results then can be used to develop a custom grazing strategy to avoid severe incidences of fescue toxicosis. Repeated testing during a grazing season can help determine possible benefits to pasture renovation or addition of legumes. Similar to testing forages for nutrient concentrations and devising a winter feeding and supplement plan, testing fescue-based pastures for endophyte infection level and for ergot alkaloid concentrations at various times during the year can facilitate management to reduce alkaloid consumption and also help determine if further mitigation is needed.
