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.

|Southeastern U.S. 2019 Vegetable Crop Handbook||
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.

|Arthropod Pest Management Research on Vegetables in Virginia – 2011||
This booklet summarizes more than 50 experiments of arthropod pest management research conducted on vegetable crops in Virginia in 2011. Experiments were primarily conducted at three Virginia Tech research stations: the Eastern Shore Agricultural Research and Extension Center (ESAREC) near Painter, VA, the Hampton Roads Agricultural Research and Extension Center (HRAREC) in Virginia Beach, VA and the Kentland Research Farm near Blacksburg, VA. All plots were maintained according to standard commercial practices.

|Florida Predatory Stink Bug||
The Florida predatory stink bug (FPSB) is a native stink bug species in the southeastern United States. It predominately occurs in neotropical regions, but can be found as far north as Pennsylvania. This species is a natural enemy that feeds on a variety of insects including many agricultural pests (Figs. 1 & 2).

|Diagnosing stink bug injury to vegetables||
In the mid-Atlantic U.S. vegetable crops are attacked by several different stink bug species (1). The primary pest species include: the invasive brown marmorated stink bug (BMSB), Halyomorpha halys, which has become the dominant species in most landscapes (2), brown stink bug, Euschistus servus Say, which is the most common species attacking tomatoes; green stink bug, Chinavia hilaris Say (3); and harlequin bug, Murgantia histrionica, which is primarilly a pest of brassica vegetables only (4). All stink bugs are piercing sucking feeders that insert their stylets into the fruit, pods, buds, leaves, and stems of plants.

|Benefits of an Insecticide Seed Treatment for Pumpkin Production in Virginia||
In recent years cucurbit growers in the Mid-Atlantic U.S. could purchase their seeds pre-treated with the neonicotinoid insecticide thiamethoxam. The insecticide seed treatment is currently packaged as FarMore F1400, which also includes three proven and complementary fungicides that provide the first line of defense against several key seed and seedling diseases including Rhizoctonia, Fusarium, Pythium, general damping-off and seedling blight.

|Summary of insecticide efficacy for control of wireworms on potatoes – Virginia (2003-2015)||
Wireworms are the subterranean larval stage of click beetles. These insects can remain in the soil for several years attacking potato seed pieces or tubers or seeds and roots of other crops that are planted in the field.

|Control of Brown Marmorated Stink Bug with Insecticide-Treated Window Screens||
In Virginia and other Mid-Atlantic states, the invasive brown marmorated stink bug (BMSB) has become a serious nuisance pest (Rice et al. 2014). Each fall, these insects aggregate on buildings seeking shelters in which to spend the winter months.

|Evaluation of the Residual Efficacy of Commercial Slug Baits||
Slugs are prevalent pests in no-till and reduced-till crop systems in Virginia. These slimy mollusks utilize plant residue to hide during the day, and at night, they feed on numerous crops causing irregular feeding holes and shredded leaves. Slugs cause the most damage during early plant growth.

Caterpillars, or the larval stage of Lepidoptera, are probably the most damaging of insect groups that feed on cole crops, such as collard, kale, cabbage, broccoli, cauliflower, kohlrabi, Brussels sprouts, and Chinese cabbage.

|Mexican Bean Beetle||
Mexican Bean Beetle (MBB), Epilachna varivestis Mulsant (Fig. 1), is an herbivorous lady beetle (Coccinellidae) that feeds on bean crops (legumes) in North America. It is similar to the squash lady beetle, Epilachna borealis, which feeds primarily on cucurbits. MBB can cause significant defoliation damage to various bean crops particularly in the genus Phaseolus (snap beans, lima beans, pole beans, etc.). It will also feed on soybean, alfalfa, beggarweed, kudzu, and other legumes.

|Improving Pest Management with Farmscaping||
Farmscaping is a holistic ecologically-based approach to pest management that emphasizes the arrangement or configuration of plants that promote biological pest management by attracting and sustaining beneficial organisms. Ideal farmscape plantings provide habitat for beneficial insects, suppress weeds, and grow in close proximity to the cash crop without competing for light, water and nutrients. Research has shown that maintaining high levels of species diversity is a key characteristic of a proper functioning agroecosystem. Unfortunately, intensive farming operations including growing large monocultures, regular cultivation, and excessive use of insecticides often leads to a dramatic reduction in arthropod diversity, especially natural enemies that often keep many pest insects below damaging levels. Farmscaping is a technique designed to add diversity back to the system and minimize disturbance leading to increases in natural enemy populations by providing insectary plants as food and shelter resources.

|Soldier Beetles (Leatherwings)||
This publication reviews the biology of cantharid beetles. Cantharids, known as soldier beetles or leatherwings, are commonly-encountered beetles throughout Virginia. Two species in the genus Chauliognathus are the most frequently observed; the margined leatherwing (Chauliognathus marginatus) is found during the spring and early summer, while the Pennsylvania leatherwing or goldenrod soldier beetle (Chauliognathus pensylvanicus) is active during the late summer and early fall. Both species visit a variety of wild and cultivated flowers, and they can be considered beneficial insects.

|Striped Cucumber Beetle||
In Virginia, cucurbits are attacked by two native species of cucumber beetles, the striped cucumber beetle, A. vittatum, which is featured in this document, and the spotted cucumber beetle, Diabrotica decimpunctata howardi (Mannerheim), which is discussed in a separate fact sheet.

Both Hawaiian beet webworm (HBW) and beet webworm (BW) have multiple generations per year, and the total number is based on temperature. In tropical and subtropical climates, HBW is active year round, and can complete a generation in about 30 days. The species cannot overwinter in Virginia, but can migrate northward during the season to become a pest in late summer and early fall. BW is found throughout the U.S., but is more common in the western states. This species has fewer generations per year and can overwinter in the soil as a mature larva.
