Kathy Lawrence

Research Activities

Ares of expertise are in soil borne and foliar fungal diseases specifically plant parasitic nematodes and fungi attacking field crops, vegetables and ornamentals with emphasis on nematode and fungal pathogen interactions and host-pathogen relationships in the natural environment. The goals of my applied research (Hatch Project # ALA015-2-14003) are to develop and evaluate ecologically based plant disease management programs for the economically important crops in Alabama, and to deliver these programs to growers. My basic research uses a multidisciplinary approach to address fundamental questions in plant parasitic nematode pathogenicity as well as fungal pathogen interactions and host-pathogen relationships
