|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.
