|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%.

|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||Nov 13, 2018||444-203 (SPES-74P)|
|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.

|New Views on the Importance of Colostrum Consumption by Piglets: Effects on Future Growth and Reproduction||
Colostrum is the first milk secreted by a sow during lactation and is produced for just 24 hours following the onset of farrowing. The substance is rich in energy, and contains antibodies and immunoglobulins required by the piglet to fight disease and infection.

|Virginia Cotton Production Guide 2016||
Proper soil fertility management ensures sufficient nutrients for maximum cotton production. Obtaining and maintaining appropriate soil nutrient concentrations is imperative, as fertilizer inputs are the largest component of production budgets for Virginia cotton farmers. At the same time, excessive nutrient application wastes money, wastes natural resources, and can negatively impact yields and environmental quality.

The 2014 grain sorghum OVT tests contained 52 hybrids; 41 hybrids were planted as a full season crop and 21 as double crop. Full season and double cropping tests were conducted at three locations, at the Tidewater Agricultural Research and Extension Center (TAREC) in Suffolk, VA, in a farmer field near Windsor, VA, in Isle of Wight County, and at the Virginia State University’s Randolph Farm near Petersburg, VA.

|IMPACT: Virginia Winter Fruit School Impact||
Tree fruits are important to the agricultural economy in Virginia. The commonwealth ranks sixth in the nation in apple production, with a crop valued at more than $68 million, and 20th in peach production, with a crop valued at $4.5 million. Although smaller in acreage, cherries, pears, and plums also play an important role in some areas of Virginia. These fruit crops are susceptible to an everchanging array of insects, plant diseases, and weeds, and pest management programs are complex and knowledge-intensive.

|Virginia Soybean Performance Tests 2015||
The purpose of this publication is to provide performance data of the many soybean varieties offered for sale in Virginia. These data should be of benefit to producers and agribusinesses in making selections of varieties for their use. It is realized that not all varieties that are offered for sale in Virginia are included in these tests. There is no implication that varieties not included are inferior in any way, but only that they have not been tested.

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 5 Virginia-type cultivars that currently are on the market and 31 advanced breeding lines tested in the Peanut Variety and Quality Evaluation (PVQE) small plots in 2015.

The primary considerations when selecting peanut varieties are yield, grade factors, disease, pests, and drought and heat response. A good practice is recording for each field the variety, yield, rainfall, and disease and insect incidence every year. This will allow producers to identify the most productive and less problematic fields, also the most productive varieties for each field.

|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.

New varieties and strains of particular varieties of vegetables are constantly being developed throughout the world. Since it is impossible to list and describe all of them, only some of the better performing commercial types are listed in the specific crop section, either alphabetically or in order of relative maturity from early to late. These varieties are believed to be suitable for commercial production under most conditions.

|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.
