Extension Interests and Current Efforts

Dr. Brannen has extensive experience with disease management programs in numerous cropping systems.  He serves as the extension fruit pathologist for Georgia – conducting research and technology transfer for multiple fruit commodities.  His efforts are directed towards developing IPM practices to solve disease issues and technology transfer of disease-management methods to commercial fruit producers.  He also teaches the graduate level Field Pathology Course, the History of Plant Diseases and their Impact on Human Societies Course, team-teaches the IPM Course, coordinates the Viticulture and Enology in the Mediterranean Region Course (Cortona, Italy), and guest lectures in numerous other courses throughout the year.
