In Mississippi, a number of vegetables are produced commercially. Many of these vegetables are grown in the field, but some vegetables, particularly tomatoes, are produced in enclosed structures (high tunnels and greenhouses). Many vegetables are also very popular in home gardens. Vegetable production, whether for commercial or personal use, is not always an easy task. A variety of disorders, insects, diseases, and pests may cause problems during any given season and may damage a crop leading to reduced or poor-quality yields.
The information available on the linked pages is intended to provide valuable information about vegetable diseases and management for the home gardener and commercial grower. All MSU Extension publications that contain information on or related to disease management in vegetables are listed on the Vegetable Disease Publications page. Events at which vegetable disease information will be presented are listed on the Vegetable Disease Calendar page. Updates or reminders pertaining to the occurrence or management of vegetable diseases as they may occur or become available will be posted on the Vegetable Disease Updates page.

Successful Mississippi gardens are filling up with beautiful tomatoes, but unless gardeners stay alert and act, these plants can succumb to summer insect pests and diseases.
MSU scientists are on the lookout for a cucurbit crop bandit. And they need your help!
Cucurbit downy mildew is a sneaky thief with the ability to quickly and significantly reduce yields or wipe out entire crops of susceptible cucurbits, including cucumbers, melons, pumpkins and squash. (File photo by Rebecca A. Melanson)
