Verticillium

A genus of fungi that includes Verticillium albo-atrum, a plant pathogen causing wilt diseases. Verticillium species invade plant vascular systems, causing wilting, stunting, and yield loss in crops including potatoes, tomatoes, cotton, and olives — with direct consequences for raw-material supply and quality. The fungi persist in soil as microsclerotia for years, making crop rotation and resistant varieties the main controls. While not foodborne pathogens themselves, Verticillium infections downgrade produce quality and increase susceptibility to secondary rots. Postharvest, affected lots must be sorted rigorously, since diseased tissue spoils faster and compromises processed-product quality.
