The Virginia Pest Management Guide (PMG) series lists options for management of major pests: diseases, insects, nematodes, and weeds. These guides are produced by Virginia Cooperative Extension and each guide is revised annually. PMG recommendations are based on research conducted by the Research and Extension Division of Virginia Tech, in cooperation with other land-grant universities, the USDA, and the pest management industry.

The 2023 Virginia performance trials of commercial corn hybrids were conducted at six locations: Blacksburg, Holland, Blackstone, Orange, Shenandoah, and Mt. Holly. Corn was planted with a Wintersteiger PlotKing 2600 planter, and harvested at maturity with a Massey-Ferguson 8XP plot combine harvester. Plot grain weights (lb/ac), grain test weight (lb/bu), at grain moisture (%) were measured with a GrainGage® by HarvestMaster. Plot grain weights have been adjusted to a standardized moisture content of 15.5%. Statistical analysis was done to determine what differences were significant.
