Introduction: Microdochium patch can be observed year-around in some cool, humid regions, and damages nearly all grass species in Western Canada and the Pacific Northwest. Microdochium patch is a major disease on golf course putting greens from September through May, and under favorable conditions, can injure or kill significant amounts of turf which greatly disrupts the aesthetics and playability of the putting green surface. Historically, more money has been spent on fungicides to combat this disease in Western Canada and the Pacific Northwest than any other turfgrass disease. Currently, fungicides applied every 3 to 4 weeks to putting greens throughout the 9 month period of disease activity are the primary means for providing control of this pathogen, which equates to roughly $20,000 annually per golf course.
