My research program is focused on the development of economic thresholds and management strategies for plant-parasitic nematodes and soilborne plant pathogens affecting grape, strawberry, raspberry, and Vaccinium species.Development of non-chemical and sustainable management options is a goal of this research. Management strategies being investigated include modified cultural practices (crop rotation, green manures and soil amendments, and soil solarization), the use of biological control organisms and compounds, and the identification of genotypes with host plant resistance
