| Abstract/Contents: | "The study was conducted in Bedford County, PA. The fairway consisted primarily of annual bluegrass (70%) and Kentucky bluegrass (30%). 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 8002VS TeeJet nozzles mounted on a 6-ft boom, operating at 28 psi, and applied in 272ml of water/36 ft² or delivering 2 gal water/1,000 ft². Granular formulations were applied with a hand-held shaker with top-dressing sand used to provide even distribution of product. At treatment time (2 May), the following soil and environmental conditions existed: air temperature, 61°F; soil temperature at 1-inch depth, 54°F; RH, 45; amount of thatch, 0.25-0.375 inch; soil textural class, silt loam; soil particle size analysis: 15.6% sand, 59.7% silt, 24.7% clay; soil percent water content (percent by weight), 34.0%; organic matter, 10.2%; water pH, 7; soil pH, 6.1; application time, late morning; and clear skies. The experimental area was irrigated with 0.1 inch of water immediately after treatment. A total of 9.73 inches of rain was recorded from 2 May through 24 Jun. Posttreatment counts were made on 24 Jun. Annual bluegrass weevil control was evaluated by removing two 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 actively observed on golf course fairways, greens, and roughs before treatment. No treatments provided significant control. Weevil populatios were highly variable within untreated checks. Weather conditions may have severely retarded spring weevil population trends. No phytotoxicity was noted." |
