​​Buckeye rot is one of a number of diseases that can affect tomatoes. This oomycete disease, caused by various species in the genus Phytophthora, affects tomato fruits and is common during periods of warm, wet weather. Topics discussed in this presentation include the basics of disease development (the disease triangle) and buckeye rot development, signs and symptoms, and management strategies. Although resources specific to Mississippi and the southeastern United States are mentioned, additional resources relevant to specific states and/or regions may be available. Local state Extension offices can provide additional information and state- or region-specific resources.
