|Control of Common Pasture and Hayfield Weeds in Virginia and West Virginia||
Annual and perennial weed control in pastures and hayfields is an important aspect of successful forage management. This publication will discuss control measures for many of the common weeds found in Virginia and West Virginia permanent fescue and mixed fescue / bluegrass / orchardgrass pastures and hayfields.

|Farm Security - “Treat it Seriously” – Security for Plant Agriculture: On-Farm Assessment and Security Practices||
Acts of terrorism have heightened our awareness of the need for increased personal and farm security. The greatest security risk to farms, greenhouses and nurseries where plants are grown is the unauthorized access to farm chemicals and application equipment.

|Fine Tuning a Sprayer with "Ounce" Calibration Method||
This extension publication discusses guidelines to quickly evaluate the performance of a sprayer. Sprayer calibration, nozzle discharge, spray pattern uniformity, speed checks, pump performance and plumbing arrangements are evaluated with minimal calculations.
Tractor-mounted, pull-type, pick-up-mounted and self-propelled sprayers are available from numerous sources. Rising chemical costs and new low rate chemicals are making accurate application more important than ever before. Proper calibration must be a primary management consideration whether one is a farmer or a custom applicator. Since most pesticides are applied with hydraulic sprayers, users should also know proper application methods, chemical effects on equipment, and correct cleaning and storage methods for hydraulic sprayers.

|Identification and Control of Annual Ryegrass in No-Till Corn in Virginia||
In Virginia, annual ryegrass has become one of the most troublesome and difficult to control weeds in small grains, as well as in corn and soybeans grown in rotation with small grains. Annual ryegrass control has declined due to the development of resistance to Hoelon, which has been the only treatment available for control in wheat and barley. Lack of control in small grains has allowed annual ryegrass to proliferate and become problematic in no-till corn establishment where high rates of triazine herbicides or sequential applications of nonselective herbicides are frequently required for acceptable control.

|Intensive Soft Red Winter Wheat Production||
New and successful techniques have been developed for intensive soft red winter wheat management by a multidisciplinary research and Extension team at Virginia Tech. Research was started in the early 1980's and continues today. The guidelines presented in this manual and the accompanying videotape are based on that research.

|Itchgrass Identification and Control in Virginia||
On October 3, 2007, the Weed Identification Clinic at Virginia Tech received an itchgrass [Rottboellia cochinchinensis (Lour.) Clayton] sample from a cornfield in Westmoreland County, near Montross (Figure 1). Currently, itchgrass is considered a federal noxious weed and the Westmoreland County sample is the first record of this plant in the state of Virginia.

|No-Till Seeding of Forage Grasses and Legumes||
No-till seeding of forage grasses and legumes can be successful and has become an accepted practice for a number of reasons. One of the primary concerns in establishing new forage stands in a well-tilled seedbed is the threat of soil erosion during the establishment period. Not only is valuable topsoil lost, but resulting ruts and gullies damage equipment and are dangerous to equipment operators. In addition to reducing soil erosion, no-till seedings conserve moisture already present in the seedbed. Moisture conservation, along with a dramatic reduction in water run-off, improves the water supply for the new seedlings. No-till seeding methods also require less time and fuel than traditional methods because rocks remain below the soil surface.

|Plumbing Systems of Agricultural Sprayers||
The plumbing systems of agricultural sprayers are usually considered foolproof. Sprayer problems may occur if plumbing and/or modifications are improperly done or maintenance is ignored. Retrofitting, addition of electrical control systems, and replacement of pumps or nozzles require proper knowledge of the plumbing system and the implications of these changes to sprayer performance. Routine maintenance of the plumbing system is essential.

|Prevention and Control of Palmer Amaranth in Soybean||
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. Four Palmer amaranth plants per 100 ft2 of row can reduce soybean yield by 12 to 17%.
