| Abstract/Contents: | "Tests were conducted on a golf course fairway in Lewiston, Pa. The fairway consisted primarily of annual bluegrass (20%), Kentucy bluegrass (40%), and perennial ryegrass (40%). Treatment plots were 9 by 6 ft, arranged in a randomized complete block design and replicated 3 times. Liquid and powder formulations were applied with a CO2 sprayer with 4 8004VS TeeJet nozzles mounted on a 6-ft boom, operating at 28 psi at delivering spray atr 5 gal/1000 ft2. Granular formulations were applied with a hand-held shaker and mixed with a fine grade of sand top dressing to facilitate product distribution. At treatment time (30 Aug) the following soil and environmental conditions existed: air temperature, 78 degrees F; soil temperature at 1 inch depth, 70 degrees F; RH, 50%; amount of thatch, 0.25-1.25 inches; soil type, sandy clay loam; soil particle size analysis: 55% sand, 24% silt, 21% sand; soil moisture, 16.8%; organic matter, 2.7%; watter pH, 6.0; soil pH, 5.1; 6.5 inches of rainfall was recorded over the posttreatment period. Immediately after treatment the experimental area replicate, and the total number of Japanese beetle grubs ft2 was recorded. An average of 21.9 grubs/ft2 was recorded on 30 Aug. Thirteen treatments significantly reduced grub populations. Ortho 16549 and 16550 G provided no reduction. No phytotoxicity was noted." |
