The overall goal of our research and extension programs is to Discover, Develop and Deliver sustainable, eco-friendly, economical  and user-friendly plant disease management tools, which can be easily integrated in whole crop production systems. The warm and humid weather of Florida is very favorable for the development of plant diseases in ornamental, vegetable and fruit crops.  In addition, increased international trade in plant commodities have led to the spread of pathogens in new niches including in Florida.  In order to avoid the spread and establishment of pathogens, our primary mission is to conduct research on the early detection, molecular diagnosis and management of fungal diseases of ornamental and other crops.  Our second mission is to disseminate scientifically sound information to clientele so that they can make informed decisions to minimize losses caused by plant diseases. In addition, we also conduct basic research in plant-microbe interaction using high throuhput molecular, genetic and cell biological approaches. In our research, we use a variety of traditional plant pathology, and high throughput molecular, genomics, proteomics and metabolomics approaches.
