Advancing Knowledge Through Turfgrass Center Research – Kerns

— Written By

Impairment of root function by soilborne plant pathogens, particularly Pythium species, is a significant problem that leads to the decline of creeping bentgrass during summer stress periods and bermudagrass during the fall, winter and spring. There are approximately 116 species are members of the Pythium genus. Turf Pathologist Dr. Jim Kerns is studying the distribution and prevalence of root-infecting Pythium species in golf course putting greens. As part of his research, his team is also developing a quantitative PCR assay to detect Pythium species. For more information contact: Jim Kerns (
