My current research involves laboratory and field investigations of Ralstonia solanacearum, the cause of bacterial wilt disease that effects a wide range of host plants, including potato, tomato, eggplant, banana, geranium, ginger, tobacco, sweet pepper, and olive. My goals are to better understand the biology and epidemiology of this disease and to use this information to develop more effective crop management strategies. Prior to work on bacterial wilt, my research at the Pee Dee REC centered on the biology, epidemiology, and integrated management of a newly emerging plant disease on turfgrass called rapid blight, caused by Labyrinthula terrestris. I initiated some of the first efforts to understand and control this new disease. Successful investigations included the identification and molecular phylogeny of the organism, tolerances of cool-season turfgrasses to rapid blight, the relationship of salinity to disease development, and the integrated management of the disease through chemical and cultural practices. In addition to my science research, I am also an historian with a primary interest in examining how plant diseases and the science of plant pathology have impacted biology, agriculture, and society. I serve as the official Historian of the American Phytopathological Society, the leading scientific society dedicated to the study of plant disease. I also currently am the E.C. Stakman Visiting Scholar at the University of Minnesota.
