| Abstract/Contents: | "The fairway consisted primarily of annual bluegrass (20%), Kentucky bluegrass (40%), and perennial ryegrass (40%). Treatment plots were 9 X 6 ft, arranged in a randomized complete block design and replicated 3 times. Liquid, WP, and SP formulations were applied by using a CO2 sprayer with 4 8004VS TeeJet nozzles mounted on a 6 ft. boom, operating at 28 psi at a spray rate of 5 gal/1000 ft2. Granular formulations were applied with a hand-held shaker and mixed with a fine grade top-dressing sand to facilitate product distribution. At treatment time (30 Aug), the following soil and environmental conditions existed: air temperature, 88 F; soil temperature at 1 inch depth, 78 F; RH, 40%; amount of thatch, 0.125-0.25 inches; soil type, loam; soil particle size analysis: 36.8% sand, 44.0% silt, 19.2% sand; soil moisture (oven baked), 20.5%; organic matter, 5.0%; water pH, 7.0; and soil pH, 5.2. Immediately after treatment the experimental area was irrigated with 0.25 inches of water. Posttreatment counts were made 27 d later (26 Sep). Three ft2 sod samples; were randomly taken from each replicate, and the total number of Japanese beetle grubs ft2 was recorded. An average of 23.1 grubs/ft2 was recorded on 20 Aug before treatment. Five treatments provided significant control. No phytotoxicity was noted. |
