Kotcon, James

Associate Professor of Plant Pathology

Dr. James Kotcon earned a bachelor of science degree in biology from the University of Wisconsin-Stevens Point, a master of science degree in plant pathology from Michigan State University and a doctorate in plant pathology from the University of Wisconsin-Madison. His research interests include such topics as: organic farming systems, agricultural pests of peach and apple, environmental impacts of pesticides on groundwater quality and on nontarget organisms, and biological control of nematodes. Dr. Kotcon’s teaching responsibilities are in the areas of principles of agroecology, sustainable living, principles of plant science, organic crop production, environmental impact assessment, diseases of economic crops, and nematology.
