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.

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.
