| Abstract/Contents: | "This trial was conducted at Amherst Country Club, Amherst, NH on a bentgrass nursery. The trial consisted of 7 treatments, replicated 4 times, with 3 sampling dates, in a RCB design. For each replicate, 20 third-instar larvae were placed in PVC cylinder on 19 Aug and treated on 20 Aug. The insecticides were applied using 32-oz, hand-held pump sprayers. Peak daytime surface temperatures were relatively cool during the treatment period 70-80° F). The volume of water and insecticide mixture per cylinder was 2 gal/1000 ft². Weather conditions were as follows: air temp, 68° F; sky, mostly sunny; wind, 5 mph. Soil conditions were as follows: surface temp, 86° F; at 1-inch depth, 75° F; at 2-inch depth, 70° F; texture, loam; sand, 44%; silt 38%; clay, 18%; moisture, 21%; organic matter, 4%. The trial was rated 1, 3 and 7 DAT by applying a solution of Joy dish soap and water to each cylinder to force live larvae to the surface for counting. Most formulations performed as well as the standard Dursban by 1 DAT. Only one formulation failed to give 90% control by 7 DAT. No phytotoxicity was observed." |
