| Abstract/Contents: | "This trial was conducted at Amherst Country Club, Amherst, NH. All treatments were applied on 27 Sept to a bentgrass nursery. The treatments were laid out in an RCB design with 1 ft buffers between plots. All liquid formulations were applied with a 2-wheel bicycle-type CO² boom sprayer equipped with 4 spray heads, fitted with a 50-mesh strainer and an 8004 fan-type nozzle. The volume of water and insecticide mix per plot was 2 gal/1000ft₂ delivered at 40psi. Granular formulations were evenly dispersed using large plastic salt shakers. All granulars were irrigated with 1/2 inch of water. No liquid formulations were irrigated. BCW larvae were predominantly 4th instar. Weather conditions were as follows: air temp, 50°F; sky, cloudy; wind, calm. Soil conditions were as follows: surface temp, 55°F; at 1-inch depth, 53°F; at 2-inch depth, 53°F; texture, loam; sand, 60%; silt, 20%; clay, 20%; soil pH, 5.7; dry matter, 80%; moisture, 20%; organic matter, 4%. The trial was rated on 4 Oct by applying to each plot a mixture of Joy dish soap and water to force live larvae to the surface for counting. Most chemical applications gave excellent control. The biologicals Condor, Crymax, and Cruiser gave poor control. No phytotoxicity was observed." |
