I have statewide responsibility for management of diseases of field crops. I coordinate and provide leadership for corn and soybean disease diagnosis and management information, and education programs for corn and soybean farmers and agribusiness professionals throughout Iowa. Through my Extension activities, I strive to increase the plant pathology expertise of my clientele in order to facilitate more effective disease management and thereby increased net returns for farmers. My research program addresses current issues in disease management of corn and soybean production and directly supports my Extension efforts.  Currently we are researching Goss's wilt of corn, caused by Clavibacter michiganensis subsp. nebraskensis, and seedling diseases of corn and soybean caused by Pythium species and Phytophthora sojae.
