Dr. Emmanuel Byamukama is an Assistant Professor and Plant Pathology Extension Specialist in the Agronomy, Horticulture, and Plant Science Department at South Dakota State University. His main role is to provide research-based information to aid growers make informed plant disease management decisions. Dr. Byamukama’s lab conducts research to address management of major field crops diseases through understanding risk factors for disease development including inoculum source, shifts in pathogen races, the role of weather, and cultural practices on disease intensity and associated yield losses.
Current research focuses on characterizing the most economically important soybean pathogen in South Dakota and the region, the soybean cyst nematode (SCN; Heterodera glycines [HG]) and management strategies to minimize the pest’s economic impact. The lab also is conducting research to characterize the races of Phytophthora root rot pathogen, Phytophthora sojae in South Dakota. Understanding the race structure is important to recommend effective resistant soybean cultivars to producers. The lab conducts research to determine the effectiveness and profitability of fungicides for various crops to ensure sustainable use of fungicides and to avoid/delay resistance development
