| Abstract/Contents: | "The fairway consisted primarily of annual bluegrass (70%) and Kentucky bluegrass (30%) in Bedford County, PA. Applications were made with flowering dogwood was in full bloom. Treatment plots were 6 X 6 ft, arranged in a RCB design and replicated 4 times. Liquid formulations were applied with CO₂ compressed air sprayer with four 8004VS TeeJet nozzles mounted on a 6 ft boom, operating at 28 psi, and applied in 272 ml of water/36 ft² or delivering 2 gal water/1,000 ft ². At the treatment time (14 May), the following soil and environmental conditions existed: air temperature, 57°F; soil temperature at 1 inch depth, 64°F; soil temperature at 2-inch depth, 60°F; RH, 35%; amount of thatch, 0.25-0.50 inch; soil textural class, loam; soil particle size analysis: 27.4% sand, 46.9% silt, 25.8% clay; soil moisture (oven dry weight), 46.6%; organic matter, 6.8%; water pH, 7; soil pH, 5.9; application time, mid-afternoon; and clear skies. The experiment area was irrigated with 0.1 inch 24 hr after treatment. Post-treatment counts were made on 20 Jun. Annual bluegrass weevil control was evaluated by removing three 4-inch cup cutter sod samples from each replicate and recording the total number of annual bluegrass weevil life stages (larva, pupa, adult) per sample. Totals were then converted to a ft² count. Annual bluegrass weevil adults were observed to be active on golf course fairways, greens, and roughs before treatment. All treatments provided significant control, Talstar F and Biflex TC being most effective. No phytotoxicity was noted." |
