| Abstract/Contents: | "The fairway consisted primarily of annual bluegrass (70%) and Kentucky bluegrass (30%). Treatment plots were 9 x 6 ft, arranged in a RCB design and replicated 4 times. Liquid formulations were applied with a CO2 compressed air sprayer with four 8004 Teejet nozzles mounted on a 6 ft boom, operating at 28 psi, and delivering 5 gal/1000 ft2. At treatment time (13 May), the following soil and environmental conditions existed: air temperature, 64 degrees F; soil temperature at 1 inch depth, 68 degrees F; soil temperature at 2 inch depth, 64 degrees F; RH, 55%; amount of thatch, 0.0625-0.125 inches; soil type, silt loam; soil particle size analysis: 33.0% sand, 55.0% silt, 12.0% clay; soil moisture (oven baked), 31.2%; organic matter, 5.0%; water pH, 7.0; soil pH, 5.8; and skies were overcast. Immediately after treatment, each replicate was irrigated with 0.06 inches of water. Posttreatment counts were made 32 DAT (14 Jun). Annual bluegrass weevil control was evaluated by removing four 0.087 ft2 sod samples from each replicate, and the total number of annual bluegrass weevil larvae were recorded and converted to a ft2 count. Sod samples were removed with a four inch diam cup cutter. Annual bluegrass weevil adults were actively observed on golf course fairways, greens, and roughs before treatment. All treatments provided significant control. No phytotoxicity was noted." |
