| Abstract/Contents: | "Tests were conducted on a golf course fairway in Lewiston, Pa. 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 and soluble powder applied with a CO2 sprayer with four 8004VS TeeJet nozzles mounted on a 6-ft boom, operating at 28 psi and delivering spray at 5 gal/1000ft2. At treatment time (30 Aug) the following soil and environmental conditions existed: Air temperature, 82 degrees F; soil temperature at 1 inch depth, 70 degrees F; RH, 50%; amount of thatch, 0.25-1.25 inches; soil type, silt loam; soil particle size analysis: 32% sand, 58% silt, 10% sand; soil moisture condition, moist; Organic matter, 2.0%; water pH, 6.0; soil pH, 5.3; 4.6 inches rainfall was recorded over the posttreatment period. Immediately after treatment the experimental area was irrigated with 0.5 inches of water. Posttreatment counts were made at 7 (6 Sep), 14(13 Sep), and 21(20 Sep) DAT. Four samples of 0.087 ft2 each were removed randomly from each replicate on each posttreatment date, and total grubs were recorded and converted to a square-foot count. Sod samples were removed with a 4-inch cup cutter. An average of 14.1 grubs/ft2 was recorded 30 Aug. Each conventional product provided significant control within 7 d. No phytotoxicity was noted." |
