Chapter VII: Disease Management
Plant diseases may be a problem in the home garden, especially during warm, wet weather. Most vegetables are susceptible to at least a few diseases, but some diseases are more of a problem than others. Root rot, leaf spots and fruit rots are the more common vegetable disease problems. Fortunately, Georgia has a long cool season from fall through spring when a wide variety of cool-season crops can be grown with significantly lower disease risk. Four types of organisms primarily cause plant diseases: fungi, bacteria, nematodes and viruses.
Diseases can occur at any stage during the course of plant growth. The rapid, accurate diagnosis of the cause of a disease, along with the implementation of a rapid treatment, is essential to ensure the protection of the crop. Certain infectious diseases caused by living, microscopic organisms have the potential to rapidly ruin a crop.

Limited tools to combat these problems is one of the major contributing factors to the high risk associated with vegetable production in general. Successful production of organically grown vegetables requires an even higher level of management for profitability to occur because even fewer control tools are available to producers using this production system. Organic producers have to rely heavily upon them minor details of vegetable culture in order to avoid problems.
This page provides an overview of the bacterial diseases in vegetable crops. The related tools listed at the end of the page provided detailed information about the identification, symptoms, and management of bacterial diseases.
This page provides an overview of the fungal diseases in vegetable crops. The related tools listed at the end of the page provided detailed information about identification, symptoms, and management of fungal diseases. It is important to have a plant diagnostics laboratory confirm the pathogen causing any diseases in a crop so that the disease can be appropriately managed. Fungi constitute the largest number of plant pathogens and are responsible for a range of serious plant diseases. Most vegetable diseases are caused by fungi. Sources of fungal infections are infected seed, soil, crop debris, nearby crops and weeds. Fungi are spread by wind and water splash, and through the movement of contaminated soil, animals, workers, machinery, tools, seedlings and other plant material.
