|Peanut Variety and Quality Evaluation Results, 2015 I. Agronomic and Grade Data||
Due to suitability to the environmental conditions and existence of a strong peanut industry tailored to process primarily the large-seeded Virginia-type peanut, growers in Virginia, North Carolina, and South Carolina generally grow Virginia-type cultivars. In the view of a common interest in the Virginia-type peanut, the three states are working together through a multi-state project, the Peanut Variety Quality Evaluation (PVQE), to evaluate advanced breeding lines and commercial cultivars throughout their production regions. The objectives of this project are: 1) to determine yield, grade, quality, and disease response of commercial cultivars and advanced breeding lines at various locations in Virginia and the Carolinas, 2) develop a database for Virginia-type peanut to allow research-based selection of the best genotypes by growers, industry, and the breeding programs, and 3) to identify the most suited peanut genotypes for various regions that can be developed into varieties. This report contains agronomic and grade data of the PVQE tests in 2015.

|Summary of insecticide efficacy for control of wireworms on potatoes – Virginia (2003-2015)||
Wireworms are the subterranean larval stage of click beetles. These insects can remain in the soil for several years attacking potato seed pieces or tubers or seeds and roots of other crops that are planted in the field. Wireworms can cause serious damage to potato crops by tunneling into tubers, which reduces yield quality and creates entry points for certain plant pathogens that can rot the tuber. Wireworms are attracted to high moisture; and densities are often higher in low-lying portions of fields. Moreover, during extended hot, dry weather, wireworms may seek out the potato tubers for moisture in addition to food; exasperating the damage. It has been well documented that wireworm damage to potato tubers increases the longer tubers are left in the ground.

|Soybean Growth and Development||
Proper management of the soybean crop requires knowledge of how environmental conditions and pests affect growth during vegetative and reproductive stages. For example, too little or too much soil moisture at certain stages may hinder growth and lower yield, and insect pests may damage the crop at one stage but not another. The information below can help you determine the proper timing of various management practices.

|The Soil and Me: A Perspective on Soil Health||
Soil is the foundation upon which our natural living world depends; it is otherwise known as the dynamic material that civilization is built on (Lindbo, Kozlowski, and Robinson 2012). Soil serves diverse functions that are critical to the survival of humanity; without the soil, life on earth is inconceivable. It represents the critical zone of the earth where life, water, minerals, and air intersect and interact (fig. 1) because the soil constantly relates with other parts of nature. The soil is considered a living, dynamic resource at the earth’s surface and has been defined as “the unconsolidated mineral or organic material on the immediate surface of the earth that serves as a natural medium for the growth of land plants” (SSSA 2015). The thickness or depth of this surface or layer varies with the type and environment of the soil.

|Importance of Farm Phosphorus Mass Balance and Management Options||
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.

|Roadside Survey of Continuous No-till and Cover Crop Acres in Virginia||
In 2009, the Chesapeake Clean Water Ecosystem Restoration Act (HB 3852/S 1816) was passed, and was intended to strengthen certain standards for the Chesapeake Bay, particularly, to address nonpoint source pollution. Nonpoint source pollution includes that of urban, suburban and agricultural runoff. Cited in the bill was the need to establish and codify the Bay-wide pollution budget, or Total Maximum Daily Loads, (TMDL) for nitrogen, phosphorous and sediment that EPA was in process of developing for the Bay. Hence all states and their perspective watersheds would have pollution caps for all sources of pollution.

|Peanut (Arachis hypogaea, L.) Nutrition||
Maintaining the right soil pH for each crop ensures optimal nutrient uptake by plants. For peanut, the recommended pH range is 5.8 – 6.2. If soil pH is higher than 6.2, manganese (Mn) or boron (B) deficiency may occur; if pH is less than 5.8, zinc (Zn) toxicity problems could be favored. Therefore, taking soil samples correctly is very important for correcting soil pH. A single composite sample should be taken for each 5 irrigated and 10 rainfed acres. This sample should be composed of 20 or more subsamples collected from an imaginary grid uniformly covering the land area. The subsamples should be well mixed together and only a small composite sample should be retained and sent to the soil lab.

|Planter/Drill Considerations for Conservation Tillage Systems||
No-till planters and drills must be able to cut and handle residue, penetrate the soil to the proper seeding depth, and establish good seed-to-soil contact. Many different soil conditions can be present in the Mid-Atlantic region at planting time. Moist soils covered with residue, which may also be wet, can dominate during the late fall and early spring and, occasionally, in the summer. Although this condition provides an ideal environment for seed germination, it can make it difficult to cut through the residue. In contrast, hard and dry conditions may also prevail. Although cutting residue is easier during dry conditions, it is more difficult to penetrate the hard, dry soils. Proper timing, equipment selection and adjustments, and crop management can overcome these difficult issues.

|Compact Soil Sampling Strategy for White Grubs||
Annual white grubs (WG) are early-season pests attacking corn seeds and seedlings (Figure 1). Heavy WG infestations can cause stand and yield losses of up to 20%. Because grubs occur in the soil, their presence in fields and subsequent damage to corn may go unnoticed until too late. Also, 30% overwintering mortality in WG densities is typical in VA. Insecticidal seed treatments such as clothianidin (PonchoTM) and thiamethoxam (CruiserTM) are the tools of choice for controlling soil insect pests. Growers typically must decide whether to purchase insecticide-treated seed well in advance of spring planting.

Along with agronomic and grade information, data on kernel and pod quality are essential for release of new peanut cultivars to ensure acceptability by the entire peanut trade. The present report contains the quality data collected on 11 Virginia-type cultivars that currently are on the market and 25 advanced breeding lines tested in the Peanut Variety and Quality Evaluation (PVQE) small plots in 2010. The small PVQE plots with 36 varieties were tested at six locations in Virginia, North Carolina, and South Carolina: Suffolk, VA, Southampton Co., VA, Martin Co., NC, Rocky Mount, NC, Whiteville, NC, and Florence, SC. At Suffolk three and at Martin Co., NC, two planting dates were achieved. For the other locations, only one planting date was done. Each genotype was replicated 3 times at each location and planting date. Varieties’ names and pedigree are presented in Table 1. Since none of the advanced breeding lines were proposed for release, PVQE seed increase plots were not planted in 2010. A detailed description of the plant material, test locations, weather conditions, and cultural practices is included in the PVQE 2010 Results. I.

|Common Diseases of Soybean in the Mid-Atlantic Region||
Common diseases of soybean are caused by viruses, bacteria, fungi and nematodes. Some diseases are spread by insect vectors and nematodes while others are spread by wind, splashing rain, or movement in soil. The best way to determine if disease control would be profitable is to first identify the diseases that are capable of causing conomic yield losses. Symptoms of disease include plant damage caused by a pathogen and the reaction of plants to infection. Signs are the visible evidence of the pathogen. Some diseases have characteristic symptoms and signs that are identifiable in the field.

|Peanut Variety and Quality Evaluation Results, 2009. I. Agronomic and Grade Data||
Peanut is an important crop for the Virginia and the Carolinas. It annually brings over $90 million to the economies of this region from over 180,000 acres planted every year. For example this year, 12,000 acres were planted in Virginia and 70,000 in North Carolina. Average yield was approximately 3,500 lb/A in both states. Due to environmental similarities and existence of a strong peanut industry tailored to process primarily the large-seeded Virginia- type peanut, growers in Virginia and North Carolina generally grow the same peanut varieties. More recently, farmers in South Carolina started to grow the large-seeded Virginia-type varieties as well. For example this year, growers in South Carolina planted approximately 70,000 acres of Virginia-type peanut. In the view of this common interest in the Virginia-type peanut, the three states are working together through a multi-state project, the Peanut Variety Quality Evaluation Project (PVQE), to evaluate advanced breeding lines and standard varieties throughout their production regions. The objectives of this project are: 1) to determine yield, grade, quality, and disease response of released peanut varieties and advanced breeding lines at various locations in the Virginia and the Carolinas, 2) develop a database for Virginia-type peanut to allow research-based selection of the best genotypes by growers, industry, and the breeding programs, and 3) to identify the most suited peanut genotypes for various regions that can be developed into varieties. This report contains agronomic and grade data of the PVQE tests in 2009.

Stink bug pests across the south eastern cotton belt consist of three main species: the brown stink bug, Euschistus servus (Say); the green stink bug, Acrosternum hilare (Say); and the southern green stink bug, Nezara viridula (L.) Due to the diverse environmental conditions across this production region, population levels of these species vary widely across seasons, states, and fields. In North Carolina and Virginia, green and brown stink bugs are the primary species, while southern green and brown stink bugs predominate in Georgia,and all three species are commonly observed in South Carolina.

|Impact of Changing From Nitrogen- to Phosphorus-Based Manure Nutrient Management Plans||
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.

Commercial greenhouse production of tobacco transplants first appeared in Virginia in the mid-1980's. Initial adoption of this technology was slow due to the high cost of the structures and equipment. However, widespread acceptance of greenhouse tobacco transplant production has occurred in the 1990's. This has largely resulted from lower greenhouse costs, increased labor costs, and the generally good experiences of early greenhouse tobacco growers.

|Phosphorus, Agriculture & The Environment||
Phosphorus (P) is a naturally occurring element that can be found in the earth's crust, water, and all living organisms. Phosphorus (P) is one of 16 elements that are essential for plant growth. Soils in Virginia are naturally low in phosphorus, and most cropping systems on these soils require supplemental phosphorus to maximize their yield potential.

|Field Production of Cut Flowers: Potential Crops||
Do you have a roto-tiller and at least 1/2 acre of land? Consider cut flower production. Commercial vegetable growers, tobacco farmers, and young people interested in summer income are all potential candidates. Andy Hankins, VCE Extension Specialist for Alternative Agriculture, notes that even large-scale grain and livestock farmers have regained some profitability in their operations by adding cut flower production. For many greenhouse and nursery operations, mid-summer business is slow relative to spring. A field-grown cut flower business is a viable option to fill in the summer production and cash flow gap.

|Getting Started in the Production of Field-Grown, Specialty Cut Flowers||
Specialty cut flowers are one of the most profitable field crops you can grow. Lynn Byczynski, editor of Growing For Market newsletter (see Resources section), estimates a value of $25,000 to $35,000 per acre for field-grown cuts. The most basic requirements are at least half an acre of open, arable land, a rototiller, and, of course, time and effort. This publication is directed to those new to market gardening, but commercial vegetable growers, tobacco farmers, and young people interested in summer income are all potential candidates. Even grain and livestock farmers have increased profitability in their operations by adding cut flower production. For many greenhouse and nursery operations, mid-summer business is slower, relative to spring. A field-grown cut flower business is a viable option to fill in the summer production and cash flow gap.

|Corn Earworm Biology and Management in Soybeans||
Corn earworm, Helicoverpa zea, is the most common and destructive insect pest of soybeans grown in Virginia. Although infestation severity varies, about one-third of our acreage is treated annually. This costs farmers 1.5 to 2 million dollars annually, and requires the application of many pounds of insecticide to crop lands. We may never eliminate this pest from Virginia soybeans, but knowledge of the biology and use of best management practices can help limit insecticide controls to those fields that meet economic threshold criteria. This publication provides current information on corn earworm biology, prediction of outbreaks, pest advisories, scouting procedures, and recently revised economic thresholds.

|The Peanut Southern Corn Rootworm Advisory||
The southern corn rootworm (SCR) has long been considered a major pest of peanuts in North Carolina and Virginia. However, researchers and Extension faculty at Virginia Tech and NC State have determined through more than 400 commercial field trials that the majority of peanut fields do not need to be treated. They have developed and tested a simple-to-use advisory that identifies those fields not at risk for pod damage or economic loss. The Southern Corn Rootworm Advisory can save you time and money as well as help you use insecticides more efficiently.

|European Corn Borer||
Description of DamageEuropean corn borer (ECB) is a major pest of corn grown for grain in Virginia. This pest is found throughout the commonwealth, but its population density fluctuates from year to year in a given locality. Typical damage to corn plants caused by this insect are reduced plant vigor leading to subsequent ear drop and stalk lodging.
When fully grown, ECB larvae are 3/4 to 1 inch in length and creamy-white to pink in color. The larval head capsule is dark brown and, on top of each abdominal ring or segment, there are several small dark brown or black spots. (Figure 1)

|Integrated Pest Management Peanut Scouting Manual||
Integrated Pest ManagementIn the competitive global peanut market, you need to lower production costs. At the same time, you also need to keep pesticide residues in peanuts to a minimum; protect rivers, streams, and lakes from runoff; and prevent chemicals from leaching through the soil to groundwater. Using IPM to protect crops only from pests that are likely to cause economic losses is a good way to meet these goals.
The Three Keys to IPM
|Nov 13, 2014||444-126|
|Slugs in Field Corn||
Scientific Names: Deroceras reticulatum (gray garden slug) (Fig. 1), Deroceras laeve (marsh slug) (Fig. 2), Arion subfuscus (dusky slug) (Fig. 3)
Size: Mature slugs vary in size from 1/2 inch to several inches in length; however, the typical size range of slugs found in cornfields is about 1/2 to 1 1/4 inches.
Color: Mature slugs are gray to brownish-gray, depending on the species. Immature slugs resemble adults in color (Fig. 4).
|May 1, 2009||444-109|
|Asiatic Garden Beetle in Field Corn||
Species: Maladera castanea (Arrow)
Size: The adult beetle is 5/16 to 7/16 of an inch long (slightly smaller than a Japanese beetle adult). A fully developed grub (third instar) measures about 3/4 inch long
Color: The adult is chestnut brown or reddish brown in color and faintly iridescent (Fig. 1). The grub (immature stage) is off white except for a distinct head capsule and three pairs of true legs that vary from in color from orange to dark brown.
Description: The beetle abdomen is covered by a pair of hardened forewings, or elytra, which are not used in flight. Instead, their main purpose is to protect the hind wings, which are folded up under the elytra when the insect is not in flight. The grub has a distinct head capsule and three pairs of true legs and will fold into a 'C' shape when disturbed (Fig. 2). It is very easy to differentiate an Asiatic garden beetle grub from other annual white grub species with the aid of a 10x power hand lens. The grub has a single transverse row of spines on the underside of the last abdominal segment, or raster, and a 'Y' shaped anal slit (Fig. 3).
|May 1, 2009||444-108|
|Root-knot Nematode in Field Corn||
Species: Meloidogyne incognita (southern root-knot nematode), M. arenaria (peanut root-knot nematode), M. javanica (Javanese root-knot nematode), M. hapla (northern root-knot nematode; not found in corn)
Size: Adult females are up to 1/16 inch in diameter.
Color: Adult females are a translucent cream color.
Description: Adult females are pear shaped and sedentary.
|May 1, 2009||444-107|
|Japanese Beetle in Field Corn||
Scientific Name: Coleoptera: Scarabaeidae Popillia japonica Newman
Size: Adult is 1/3 to 1/2 inch long; the fully developed grub or larva is 1/2 to 1 inch long.
Color: The adult is shiny metallic green with copperbrown wing covers and is characterized by the presence of five tufts of white hairs which protrude from under the wing covers along each side of the abdomen, with two additional tufts of white hairs on the tip of the abdomen (Fig. 1); the grub has a distinct head capsule that is dark brown to orange in color with the rest of the body an off-white or grayish color due to the presence of soil or fecal matter in the hindgut (Fig. 2).

|Using the Virginia Cooperative Extension Climate Analysis Web Tool to Better Manage and Predict Wheat Development||
Wheat development is affected by nutrients, water, light, and other factors; but temperature consistently determines how quickly or slowly plants move ahead in forming leaves, roots, tillers, and grain heads. The plant's development stage at any point during the season is affected very predictably by how warm or cool the season has been up to that point. This knowledge, combined with educated guesses about how the rest of the growing season will progress, can be extremely valuable information to the grower, who can then make more informed management decisions to include predicting the maturity/harvest schedule.

|Defoliating Cotton under Adverse Conditions: Drought-stress, Cool Temperatures, and Rank Growth||
Modern chemical harvest aids are applied to induce leaf abscission, hasten mature-boll dehiscence, and inhibit regrowth (Gwathmey and Hayes 1997; Snipes and Cathey 1992). Their use can result in increased machine harvest efficiency and fewer lodged plants while reducing boll rot, the trash in seed cotton, and the time from defoliation to harvest (Benedict 1984). The challenge of using harvest aids is the inconsistent way cotton responds to them, making defoliation one of the most unpredictable management practices (Benedict 1984; Gwathmey and Hayes 1997).

|Soil Test Note #2 - Field Crops||
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.

|Land Application of Broiler and Turkey Litter for Farming Operations Without a DEQ Permit||
Poultry litter (poultry manure and a bedding material such as sawdust, pine bark, or peanut hulls) is a good source of nutrients and organic matter for growing crops. Land application of poultry litter on farms has been the mainstay of effective and safe usage for years. Unfortunately, improper management of litter applications may cause nutrient enrichment and/or contamination of surface and ground water resources. The key to proper management is an understanding of the nutrients available in the litter, the nutrient requirements of the crops to be produced, and the potential for the litter and/or nutrients to reach surface or ground waters.

|Manure Spreader Calibration for Rear-discharge Equipment -- Handling Solid and Semi-solid Manures and Poultry Litter||
To maximize crop productivity and minimize adverse environmental effects, it is critical that land applications of manures meet, but not exceed, crop nutrient requirements. To assure that the actual manure application rate matches the desired application rate, manure-spreading equipment must be calibrated. The goal of manure spreader calibration is to determine the amount of manure, on a weight per unit area basis, that is being applied to a field. This publication describes three methods for manure spreader calibration for spreaders handling solid and semi-solid manures.
