Microdochium nivale is the most important turfgrass disease in the Pacific Northwest (Vargas, 1994). Even though this disease can be observed year round, it is particularly devastating in the winter months. During this time of year, the turf is no longer actively growing, often leaving scars until the warmer spring temperatures return with the start of a new golf season. In order to combat this disease, golf course superintendents are required to make applications of fungicides, sometimes monthly from late fall to early spring.

Cross-Border Meeting Discusses #1 BC Turf Disease

Immediately after Alec Kowalewski’s turf disease talk at the 2013 NTA conference in Tri-Cities, Washington, I contacted Peter Sorokovsky, WCTA Research Committee Chair to ask about his successes battling Microdochium nivale, aka pink snow mold or Fusarium patch, at Riverway and Burnaby Mountain Golf Courses.

Promising Poa Products On The Horizon

Research at a number of universities in the United States on a new product for the reduction of annual bluegrass (Poa annua) in creeping bentgrass is causing quite a bit of excitement for golf course Superintendents.

Creeping bentgrass (Agrostis stolonifera L.) golf greens infested with annual bluegrass (Poa annua L.) can be hard to manage, unattractive, and have reduced playability. Methiozolin (‘PoaCure’) is a relatively new isoxazoline herbicide that has shown selective P. annua control in golf greens.

Management, host pathogenicity, and identification of Magnaporthe poae, causal agent of summer patch on annual bluegrass turf.

Project summary:

Summer patch, a root disease caused by the fungus Magnaporthe poae, is most pathogenic on annual bluegrass (Poa annua) golf course greens in North America. Disease symptom development can occur when the turfgrass is stressed, although M. poae thrives best under conditions of high air and soil temperatures, high soil moisture and high soil pH.
