Abstract
A creeping bentgrass (Agrostis palustris Huds. ‘Penncross’) green was treated with the herbicide ethofumesate at single and sequential applications during 2 years. A single ethofumesate application in September at 1.1, 1.7, or 2.2 kg a.i./ha slightly discolored bentgrass, but turfgrass quality was not significantly reduced. With October treatments, discoloration increased at 1.7 and 2.2 kg a.i./ha, but not at 1.1 kg. Ethofumesate treatments made in September and October resulted in less discoloration and reduced quality less than with applications made in October and November. Bentgrass treated in October and November was severely injured in 1 of 2 years, but turfgrass fully recovered by the following spring with no stand loss. Chemical names used: (±)-2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranylmethanesulfonate(ethofumesate).
