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.

This guide lists vegetable varieties that are available and are adapted to the mid-Atlantic region, gives an overview of cultural practices, and list chemicals recommended to manage pests, diseases and weeds in vegetable crops. New varieties of vegetables are constantly being developed throughout the world. While all efforts are made to have comprehensive lists, not all varieties that are adapted will be listed.

This handbook represents a joint effort among Extension specialists and researchers from 15 land-grant universities in the U.S. who work in vegetable production. These specialists and researchers represent a wide array of disciplines: agricultural engineering, agribusiness, entomology, food safety, horticulture (vegetable production), plant pathology, postharvest physiology, soil science, and weed science. This handbook comprises up-to-the-minute information from research and Extension projects conducted throughout the southeastern United States. The key idea behind this handbook is to provide you with a practical resource that conveniently fits on your dashboard. It contains the information that you need to manage your vegetable crops, including which varieties to plant, planting dates, fertilizer recommendations, cover crop selection and conservation tillage options, pesticide selection, grafting, fertigation, plasticulture, postharvest handling, alternative pest management tools, and suggestions, as well as many other topics.
