Abstract/Contents:"The fairway consisted primarily of annual bluegrass (70%) and Kentucky bluegrass (30%) in Bedford County, PA. Applications were made when 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 a 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 ft². At the treatment time (14 May), the following soil and environmental conditions existed: application time, mid-afternoon; 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; and clear skies. The experimental area was irrigated with 0.1 inch of water 24 hr after treatment. Post-treatment counts were made on 14 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 but the combination of Merit 75WP and Tempo 20WP provided optimum annual bluegrass weevil suppression. No phytotoxicity was noted."
