Research Interests 

Brown SpotsMy research program uses laboratory and field experiments to study fungal diseases of peanut and methods for control.  Specifically my lab works to 1) identify components of resistance of peanut plants (Arachis hypogaea) to infections by fungal pathogens, 2) determine practices that can reduce disease development under organic production systems, and 3) evaluate the curative activity of fungicides used in conventional production systems.  Pathogens of interest include Cercospora arachidicola, the cause of early leaf spot, Cercosporidium personatum, the cause of late leaf spot, and the seed and seedling pathogens Rhizopus stolonifer and Aspergillus niger.
