| Abstract/Contents: | "An experiment was conducted in 1990 to evaluate the effectiveness of several products for their ability to suppress bermudagrass growth and annual weed control. Treatments included cimectacarb (ethyl 4-cyclopropyl (hydroxy) methylene-3, 5-dioxocyclohexane carboxylate) at 0.67, 0.90 and 1.12 kg ha-1, sethoxydim (2-[1-(ethoxyamino) -butyl]-5-[2-(ethylthio)-propyl]-3-hydroxy-2-cyclohexene-1- one) at 0.31, 0.38, and 0.45 kg ha-1, alone, and in combination with sulfometuron (2-[[[[(4, 6-dimethyl-2-pyrimidinyl) amino] carbonyl] amino] sulfonyl] benzoic acid) at 0.05 kg ha-1. All treatments of sethoxydim included a crop oil at 0.5% v/v. The experimental design was a randomized complete block with three replications. Treatments were applied to actively growing bermudagrass on 29 May using a CO[subscript]2- powered hand held boom sprayer. Plots were mowed to a height of 63 mm prior to treatment. Treatments were evaluated monthly for bermudagrass canopy height, bermudagrass seedhead suppression, bermudagrass phytotoxicity, and annual weed control. Analysis of bermudagrass canopy height indicated all treatments significantly reduced canopy height at 1 month after treatment (MAT) as compared to the untreated check. At 2 MAT, all treatments were significantly reducing canopy height. Cimectacarb reduced canopy height as great as 70% and sethoxydim as great as 51%. At 3 MAT only cimectacarb treatments significantly reduced canopy height. The addition of sulfometuron did not have a significant effect on bermudagrass canopy height. All treatments significantly reduced bermudagrass seedheads at 2 MAT. AT 3 MAT, very little seedhead suppression was observed. Cimectacarb + sulfometuron treatments significantly controlled large crabgrass at 2 MAT. Large crabgrass slowly returned by 3 MAT. Cimectacarb alone did not have the ability to control large crabgrass. Sethoxydim alone and in combination with sulfometuron significantly controlled large crabgrass at 1 MAT, 2 MAT, and 3 MAT. All treatments of sethoxydim, alone, produced significant bermudagrass phytotoxicity at 1 MAT. Higher rates of sethoxydim produced significant phytotoxicity at 2 MAT. Sethoxydim + sulfometuron, and all cimectacarb treatments produced temporary bermudagrass phytotoxicity which would be acceptable for roadside turf." |
