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.

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.
