| Abstract/Contents: | "Two trials were conducted at Amherst Country Club, Amherst, NH. In the first trial treatments were applied on 6 Sep to a bentgrass nursery and rated 13 Sep. In the second, treatments were applied 12 Sep and rate 19 Sep. The treatments were applied in an RCB design, 4 replicates per treatment, with 1-ft buffers between plots. All treatments were applied with a 2-wheel bicycle type CO₂ boom sprayer, using four 8004 nozzles with 50-mesh screens.The volume of water and insecticide mix per plot was 2gal/1000ft₂ delivered at 40 psi. BCW larvae were predominantly 3rd-4th instar in the 1st trial and 1st-2nd instar in the 2nd trial. Weather conditions were as follows: on 6 Sep, air temp, 81°F; sky, clear; wind, calm. Soil conditions were as follows: surface temp, 83°F; temp at 1-inch depth, 74°F; soil pH, 5.7; dry matter, 80%; moisture, 20%; organic matter, 4%; soil texture, loam; sand, 60%; silt, 20%; clay, 20%. On 12 Sep, sir temp was 74°F; soil temp at surface was 71°F; at 1-inch depth, 69°F. The trials were rated for live larvae by soaking each plot with Joy dish soap and water to force larvae to the surface. In both trials, the three rates of RH-0345I01, from lowest to highest, gave fair to excellent control. Cyfluthrin and Dursban also gave excellent control. Merit had no measurable effect on larval mortality. No phytotoxicity was observed." |
