Buckeye Rot (Phytophthora spp., including P. capsici)
Buckeye rot caused by the pathogen Phytophthora spp. can become a major problem in processing tomato production during periods of heavy rainfall which lead to saturated soils. The pathogen can infect developing green tomatoes which are sitting in free water or on saturated soils causing them to rot. Infected tomatoes will develop concentric tan/brown lesions (see picture).
