The Vegetable and Strawberry Pathology Program focuses on disease challenges facing the production of these crops in California, especially disease caused by soilborne fungi such as Athelia, Fusarium, Macrophomina, Sclerotinia, Stromatinia, and Verticillium. To understand these diseases the Program will integrate various research approaches that could include cropping systems, epidemiology, host resistance, pathogen biology, remote sensing, or soil ecology. Research projects will directly support extension efforts to provide improved disease management options to growers and to improve the economic, environmental, and social sustainability of the California vegetable and strawberry industries.
