Potential of Fusilade, Poast and CGA 82725 for Control of Weedy Grasses in Woody Nursery Crops and Groundcovers

To assess crop safety, Fusilade (fluazifop-butyl), Poast (sethoxydim) and CGA 82725 (2-Propynyl 2-(4-([3,5-dichloro-2 pyridinyl] oxy) phenoxy) propanoate) were applied to nursery crops and groundcovers. Of the species tested, injury was minimal except on Juniperus horizontalis ‘Bar Harbor’ with both Fusilade (fluazifop-butyl) and CGA 82725 and on Carpobrotus edulis with Fusilade where serious injury occurred. In field tests, both Fusilade (fluazifop-butyl) and Poast (sethoxydim) controlled established bermudagrass (Cynodon dactylon) in both established and newly planted groundcovers and dichondra (Dichondra micrantha) without injury at 1.12 and 2.24 kg/ha (1.0 and 2.0 lb/A).
