Prevention and Control of Palmer Amaranth in Cotton
Palmer amaranth (Amaranthus palmeri), a member of the "pigweed" family, is one of the most troublesome weeds in many southern row crops. Seed can germinate all season and plants can grow to over 6 feet in height. Plants have either male flowers that shed pollen or female flowers that can produce up to 600,000 seed per plant. One Palmer amaranth per 30 foot of row can reduce cotton yield by 6 to 12%.

Peanut Variety and Quality Evaluation Results, 2008
Peanut is an important crop for the Virginia – Carolina region. It annually brings over $90 million to the economies of this region from over 180,000 acres planted every year. For example this year, 24,000 acres were planted in Virginia and 98,000 in North Carolina. Average yield was 3,400 lb/A in Virginia and 3,500 in North Carolina. 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.

Description and Performance of the Virginia-Market-Type Peanut Cultivars
While the runner-type peanut is the predominant market type grown in the United States, the Virginia-Carolinas region has traditionally grown only the largeseeded, Virginia-type peanut. There are several old — as well as new — Virginia-type cultivars available to the peanut industry. While information on older cultivars is available in Extension publications, information on the most recently released cultivars is lacking. Therefore, this publication will provide growers, shellers, and processors with the latest research-based information on the performance of the newest cultivars and currently grown cultivars.

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.

Aphids in Virginia Small Grains: Life Cycles, Damage and Control
Four species of aphids attack small grains in Virginia — greenbug, corn leaf aphid, bird cherry-oat aphid, and English grain aphid. In general, these aphids are small pear-shaped insects (1/16 to 1/8 inch long) that are green to nearly black, or sometimes pinkish in color. Immature aphids look just like adults except smaller. Both winged and wing-less forms can occur in the same colony. All grain aphids have a pair of conicles, tailpipe-like projections, on the top side of the tail end. Aphids feed singly or in colonies on upper and lower leaf surfaces and stems. They feed near plant bases when plants are young or during cold weather, and on upper-canopy leaves, stems, and even grain heads later in the season.

Integrated Pest Management Peanut Scouting Manual
In 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.

Identifying Soybean Fields at Risk to Leaf-Feeding Insects May 1, 2009 444-203
Cereal Leaf Beetle, Biology and Management
Cereal leaf beetle, a native to Europe and Asia, was first detected in Michigan in 1962. Since that time it has spread throughout most of the mid-western and eastern United States and has become a significant pest of Virginia and North Carolina small grains. This insect can become very numerous in small grain fields and the larvae are capable of reducing grain yield by eating the green leaf tissue.

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.

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.

2009-2011 Performance of Sorghum Hybrids in the Virginia-Carolina Region
Based on data from the U.S. Grain Council (www.grains.org), grain sorghum is the third most important cereal crop grown in the United States and the fifth most important cereal crop grown in the world. The United States, with approximately 9.7 million acres harvested in the 2009-10 cropping season, is the world’s largest producer of grain sorghum, followed by India and Nigeria. Sorghum production in the U.S. is concentrated in the central and southern plains of five states — Kansas, Texas, Nebraska, Oklahoma, and Missouri — representing approximately 89 percent of total production. In many parts of the world, sorghum has traditionally been used for food. In the United States, sorghum is primarily used for animal feed, but also for food and industry derivatives such as wallboard and biodegradable packaging materials. Recently, sweet sorghums have been considered for bioenergy feedstock production.

Soybean Reproductive Development Stages
Remove the soybean plant at ground level to make it easier to stage. Examine each main stem node one at a time to determine the development stage. Focus on the top four nodes that contain fully developed leaves (shown below). A fully developed leaf is one that is located immediately below a node containing a leaf with unrolled or unfolded leaflets (leaflet edges are no longer touching). The soybean crop is considered to be at a particular stage when 50% of the plants reach that stage. Listed with stage description for R1 through R6 are the approximate number of days to R7, or physiological maturity, for full season (FS) soybean planted in May and double crop (DC) soybean planted in June/July.

Disease Management in No-Till Corn in Virginia
No-till cropping avoids the use of tillage for seedbed preparation or weed control, and crop residues left on the soil surface reduce soil erosion, minimize runoff, and increase soil moisture. No-till cropping has several advantages in terms of reduced crop production costs (fuel, labor, machinery) and soil conservation, but alterations to the biotic and abiotic environment in no-till compared to conventionally tilled fields provide unique challenges in terms of insect, weed, and disease management. The following provides recommendations for disease management in no-till corn but can be applied to other no-till cropping systems. Disease incidence and severity is not necessarily greater in no-till compared to conventional tillage, and in some cases disease may be reduced. Effects of no-till on diseases are variable and dependent on the specific pathogen, crop, and environment.

Double Cropping Soybeans In Virginia
Double cropping is simply growing and harvesting two crops in one year. In the mid-Atlantic region of the United States, soybeans are commonly double-cropped after a winter small-grain crop, usually wheat. However, double cropping is not limited to the small-grain-soybean system. Other crops, such as grain sorghum or even corn, could fit into a double-cropping system with small grains. Soybean can be grown after other winter crops, such as canola, or after a spring crop, such as snap beans. As long as both crops can complete their development in time to allow profitable production of the entire system, numerous double-cropping systems are possible.

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.

Enhanced Efficiency Fertilizer Materials: Nitrogen Stabilizers
The recent increase in fertilizer costs, especially nitrogen fertilizers, has resulted in technologies that may improve nitrogen use efficiencies in agronomic cropping systems. Many of these technologies are designed as fertilizer additives to increase fertilizer use efficiencies by increasing plant fertilizer uptake and crop yields. The resulting fertilizer formulations include some type of extra additive within the formulation or applied as a coating and are often referred to as “enhanced efficiency fertilizers” (EEFs).

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.
