| Abstract/Contents: | "The study was conducted on an irrigated fairway at Crockett's Green Hills Golf Course, Clyde, Ohio. Insecticides were applied 2 May to plots 10 X 10 ft arranged in a RCB design replicated four times. Two of the treatments were split applications in which the second applications were made 20 May. The liquid treatments were applied with a CO₂ sprayer and Teejet^D]T^D]M XR8006VS nozzles at 25 psi pressure that delivered a volume of 1 gal/1000ft². There was no immediate post-treatment irrigation. The area did receive supplemental irrigation sufficient to maintain turf quality. Environmental conditions at the time of treatments on 2 May were as follows: ants-extensively mound building activity observed, approximately 5/yd²; turf-3° slope, dry, 1 inch ht, 50% Kentucky bluegrass, 50% perrenial ryegrass, no thatch; soil-moist, 48°F at 1 inch and 47°F at 3 inch; weather-sunny, 54°F, 0-7 mph. Environmental conditions at the time of re-applications on 20 May were as follows: ants-actively building mounds, approximately 3/yd²; turf-3° slope, dry, 1 inch ht, 50% Kentucky bluegrass, 50% perennial ryegrass, no thatch; soil-moist, 68°F at 1 inch and 65°F at 3 inch; weather-sunny, 76°F, 0-10mph. Evaluations were done on 20 May, 30 May, 13 Jun, 22 Jul, and 26 Aug (18, 28, 42, 81, 116 DAT, respectively) by counting the number of active mounds in two 1-yd² areas in each plot. Analysis on Variance was done on plot totals and means separated by LSD test (P=0.5). At 18 DAT, all treatments except three granular formulations (bifenthrin 0.5G, Merit 0.5G and Dursban 1% bait) reduced the mounds by at least one half. All liquid treatments except Merit 75WP and Dursban 6.6% RTS gave significant reductions. At 28 DAT, all treatments except Dursban 6.6% RTS and Merit 0.5G showed significant reduction of ant mounds. Merit 75WP, bifenthrin 0.5G, and Dursban 1% bait showed increased reductions compared with that at 18 DAT. Merit 0.5G and Drusban 6.6% RTS still showed no effect. Significant differences were not observed among the treatments with one another and with the check at 42, 81 and 116 DAT. There were no signs of phytotoxicity from any of the treatments." |
