Efficacy of Advance Ant Bait in Turf; 1997

This trial was conducted at White Mountain Country Club, Ashland, NH. Five replications of 3 treatments were applied on 24 Jul on a bluegrass fairway. Each plot was 140 ft2, separated by 5-ft buffers on all sides; the plots were arranged in a RCB design. The ant bait was distributed evenly onto each plot using a commercial salt shaker. Dursban was applied using a 2-wheel bicycle-type boom sprayer equipped with 4 spray heads; each head was fitted with an 8005 flat fan-type nozzle and a 50-mesh strainer. The volume of water and Dursban mix per plot was 2 gal/1000 ft2, using CO2 as a pressure source at 40 psi. Weather conditions were as follows: air temp, 70°F; sky, cloudy; wind, 5-10 mph. Soils conditions were as follows: surface temp, 76°F; at 1-inch, 78°F; at 2-inches, 78°F; texture, loam; sand, 44%; silt, 42%; clay, 14%; moisture, 20%; organic matter, 6.3%; pH, 5.2. All active anthills per plot were counted prior to spraying and then every 7 days for 4 weeks after treatment.
