Abstract/Contents:"This trial was conducted at Campbell's Scottish Highlands Golf Course, Salem, NH. All treatments were applied on 27 Aug to a bentgrass chipping green. Treatments were replicated six times in RCB design. Granular formulations were applied with a Scott's 20-inch drop spreader. All liquid formulations were applied with a 2-wheel bicycle-type CO₂ boom sprayer with four 8005 fan-type nozzles using 50-mesh screens. The volume of water and pesticide mix per plot was 2 gal/1000 ft² delivered at 40 psi. All treatments were mowed 24 hrs after application. Some treatments were irrigated after treatment, some were not; also, grass clippings were removed from some treatments, and clippings were left on the plots in others. The untreated check was not irrigated and clippings were removed. All irrigated treatments received 0.1 inch of water, but even non-irigated plots received heavy dew. One DAT, and after mowing, 20 BCW larvae in second and third instar were placed in each 6-inch cylinder. Weather conditions were as follows: air temp, 80.1°F; sky, mostly sunny; wind, light breeze. Soil conditions were as follows: surface temp, 78.3°F; temp at 1-inch depth, 78.8°F; at 2", 76.5°F; soil texture, loamy sand; sand, 87%; silt, 9%; clay, 4%; soil pH, 7.2; moisture, 9.1%; organic matter, 2%; thatch depth (natural), 0.125-inch. The trial was rated on 31 Aug, 4 Sep, and 11 Sep by applying to each cylinder a mixture of Joy dish soap and water to force live larvae to the surface for counting. Watering and clipping regimes made no difference in the efficacy of Mach-2 SC. The presence or absence of clippings made no difference in Talstar efficacy. Mach-2 SC performed as well as Talstar. Mach-2 G performed slower than SC formulations, generally requiring 7-14 days to achieve the same degree of efficacy. The best granular performance occurred when clippings (and granules) were not removed and granules were not watered. Heavy dew activated these granules, and roaming cutworms received a concentrated dose of Mach-2. For best control with granules, water very lightly and delay mowing."
