| Abstract/Contents: | "The fairway consisted primarily of annual bluegrass (40%), Kentucky bluegrass, (40%), and perennial ryegrass (20%). Treatment plots were 9 x 6 ft, arranged in a randomized complete block design and replicated 3 times. Granular formulations were applied with a hand-held shaker and mixed with a fine grade top-dressing sand to facilitate product distribution. Liquid formulations were applied with a CO2 compressed air sprayer with 4 8004VS TeeJet nozzles mounted on a 6 ft boom, operating at 28 psi, and delivering 5 gal/1000 ft2. At treatment time (25 Aug) the following soil and environmental conditions existed: air temperature, 82° F.; soil temperature at 1 inch depth, 74° F; soil temperature at 2 inch, 74° F; RH, 92 %; amount of thatch, 0.125-0.25 inches; soil type, loam; soil particle size analysis: 45.3% sand, 45.6% silt, 9.1% clay; organic matter, 2.6%; soil moisture (oven baked), 22.1; water pH, 7.0; soil pH, 5.6; and clear skies. Immediately after treatment the experimental area was irrigated with 0.25 inches of water. Posttreatment counts were made 34 d later (28 Sept). Three ft2 sod samples were randomly taken from each replicate, and the total number of Japanese beetle grubs ft2 was recorded. An average of 11.0 grubs/ft2 were recorded on 25 Aug. All treatments provided significant control. No phytotoxicity was noted." |
