Research Focus

Research efforts have focused primarily on determining the biology and ecology of soilborne pathogens (both pathogenic fungi and plant-parasitic nematodes) that are impacting the production of vegetable and food legume crops. Investigations on the management of plant diseases have followed the strategies and approaches of integrated pest management (IPM). Special research efforts have dealt with microbial interactions, soil health issues and sustainable practices for disease and crop management.
