Abstract
Abstract Tests were conducted at the Preston Country Club, Kingwood, WV. Entire greens ranging in size from 3,780 to 10,350 sq. ft. were used as test plots. Treatments were applied 17 Aug. Each treatment was applied to 2 greens with a Broyhill sprayer mounted on a Cushman vehicle. The average amount of spray used was 3.2 gal/1000 sq. ft. Greens were irrigated within 0.5 h after treatment with about 5 gal water/1000 sq. ft. There was no precipitation during the trial period. Rates of applications [lb (AI)/gal] were calculated on the basis of the amount of spray used for each green; intended rates (based on sprayer calibration and mixtures) were Baythroid 0.04 and 0.06, Cymbush 0.04 and 0.06, Pounce 0.05 and 0.2, FMC 54800 0.02, PP 321 0.04, and Triumph 1.0. Prior to treating and before mowing, all greens were examined for active cutworm burrows and the numbers recorded. Counts of active burrows were made in the same manner 3 DAT and the difference from pretreat counts are expressed as % control.
