Abstract/Contents:"This trial was conduted at Amherst Country Club, Amherst, NH. Four replicates of each treamtnet were laid out on a bentgrass nursery. At 4-, 2- and 1-week intervals prior to installation of larvae, the insecticides were applied on their respective areas. Liquid formulations were applied with a 2-wheel bicycle-type CO₂ boom sprayer equipped with 4 spray nozzles; each nozzle was fitted with an 8005 fantype nozzle and a 50-mesh strainer. The volume of water and insecticide mix per plot was 2 gal/1000 ft² delivered at 40 psi. Granulars were evenly dispersed using large commercial-style salt shakers, and were irrigated to approximately 1/4-inch of water per plot. Weather conditions on each spray date were as follows: 4-week intervals (25 Jul): air temp, 66° F; sky, overcast; soil surface temp, 66° F; at 1-inch depth, 67° F; at 2-inch depth, 66° F; 2-week interval (8 Aug): air temp, 72° F; sky, mostly sunny; soil surface temp, 70° F; at 1-inch depth, 68° F; at 2-inch depth, 66° F; 1-week interval (15 Aug): air temp, 66° F; sky, cloudy; soil surface temp, 67° F; at 1-inch depth, 66° F; at 2-inch depth, 65° F. Soil analysis resulted in the following: texture, laom; sand, 44%; silt, 38%; clay, 18%; soil pH, 5.7; moisture, 21%; organic matter, 5%. PVC cylinders were installed in all plots, and 19 3rd-instar larvae were put into each cylinder on 22 Aug. The trial was rated at 1-, 3-, and 7-day intervals after intallation of larvae by applying a mixture of Joy dish soap and water to each cylinder to force live larvae to the surface for counting. Tempo was the only treatment that provided significant control compared to the check. No phytotoxicity was observed."
