Nature of position: My research and extension interests are in the development of integrated strategies for weed management in vegetable crops and strawberries. The management of weeds in most these crops is complicated by the limited number of herbicide options as well as carryover concerns. In partnership with growers, commodity organizations, Extension Farm Advisors, Extension Specialists, USDA-ARS Researchers and Pest Control Advisors we are developing strategies to maximize the value of currently available weed management tools. My research program can be divided into three area: soil seedbank ecology, weed ecology and weed management. My outreach activities focus on providing educational materials on the biology, ecology, and management of weeds in California vegetable crops, and strawberry.
