John C Rupe

John C. Rupe is a University Professor in the Department of Entomology and Plant Pathology at the University of Arkansas. He serves as Director of the Division of Agriculture Experiment Station. His academic background includes a B.A. in Biology from Goshen College, B.S. and M.S. in Plant Pathology from Colorado State University and the University of Kentucky, and a Ph.D. in Plant Pathology from the University of Kentucky.

Dr. Rupe's research focuses on soybean disease epidemiology and management, including seedling diseases, charcoal rot, frogeye leaf spot, and sudden death syndrome (SDS). He investigates fungicide efficacy, seed treatment strategies, and genetic resistance mechanisms. His work emphasizes crop resilience under environmental stress and integrates molecular techniques with field trials.

His teaching includes advanced plant pathology courses on quantitative epidemiology and soybean disease management. Key research areas include soybean-fungus interactions, seed vigor, and sustainable crop protection practices. His findings contribute to improved agricultural practices in Arkansas and globally.
