Abstract/Contents:"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 22 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 gal/1000 sq ft. Greens were lightly syringed immediately after treatment. Total precipitation during the trial period was 0.57 inches occurring 4 DAT. Rates of application {lb (AI)/acre} were calculated on the basis of the amount of spray used for each green; intended rates (based on sprayer calibration and mixtures) were Baythroid 2E and 10W, 0.02 and 0.04; PP321, 0.01 and 0.02; FMC 54800, 0.02 and 0.04; and Triumph 1.0. Treatments were evaluated by counting the number of larvae on 1/2 of each green that were flushed to the surface by the treatment 1 to 4 h after application. Then, at 7 DAT, one green in each treatment was retreated with Baythroid 2E at 0.04 lb (AI)/acre and the entire green checked for larvae flushed to the surface. An untreated nursery green was sprayed with Baythroid at the 7 DAT period, number of larvae flushed to the surface of this green (3,235 sq ft total) was 48. All treatments resulted in >97% control and no additional treatments were required throughout the remainder of the season. All compounds showed excellent flushing activity of cutworm larvae when examined 1 to 4 h after spraying; larval length ranged from 0.4 to 1.5 inches. No phytotoxicity was noted."
