Plant diseases on subtropical crops indirectly reduce yields by debilitating the plant, and directly reduce the yield and quality of the fruit before and after harvest. Our research focuses on the identification, biology, epidemiology and control of pathogens associated with subtropical crops in California, including new potential threats, and addresses how these pathogens interact to contribute to subtropical crop decline
