Mowing height and post‐application irrigation influence annual bluegrass control with methiozolin

Crop, Forage &Turfgrass Management, Volume 11, Issue 1, June 2025.
Abstract Methiozolin was registered for preemergence and postemergence annual bluegrass control in 2019 and offers good cool‐season turfgrass safety. The methiozolin label indicates that a higher rate is required to effectively control annual bluegrass (Poa annua L.) at mowing heights greater than that of typical golf course putting greens ...
