Non-Chemical Control of Annual Bluegrass (Poa annua) in Bermudagrass (Cynodon spp.) via Fraise Mowing: Efficacy and Barriers to Adoption

Fraise mowing is a maintenance practice that may serve as non-chemical means of controlling the problematic weed annual bluegrass (Poa annua L.) in bermudagrass (Cynodon spp.) given reports efficacy on other turfgrass species. However, an understanding practitioner decision-making implementing fraise weed-control measure remains unknown. A field study was conducted Knoxville, TN and repeated space Jay, FL during summer 2019 to assess regrowth subsequent control, following at depths 1.5 3.0 cm compared non-treated check (0 cm). Bermudagrass recovered more quickly depth than swiftest Florida. either resulted 41–97% reduction populations. qualitative spring 2021, which engaged eight managers from Tennessee Florida via individual interviews order understand barriers challenges application. Turfgrass had positive views but described implementation for control including cost, labor, area closure, debris removal.
