Control of Ants with Talstar and Amdro, 1996

Abstract

This trial was conducted on a fairway at Indian Mound Country Club, Ossipee, NH. The initial count of ant hills was taken on 28 Jun, prior to treatment applications. The layout was an RCB design, using 15 X 7 ft plots allowing 1-ft buffers between plots. Talstar F (0.2 lb) and Talstar G (0.2 lb) were re-treated 14 DAT. 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 40 psi. Granular formulations were evenly distributed over the plots using large plastic salt shakers. All granular treatments were irrigated with 1/2 inch of water; no liquid treatments were watered in. Weather conditions at time of initial application were as follows: air temp, 74°F; sky, mostly sunny; wind, light breeze. Weather conditions at time of reapplication were as follows: air temp, 60°F; sky, partly cloudy. Soil conditions were as follows: surface temp, 68°F; at 1-inch depth, 65°F; at 2-inch depth, 65°F; texture, loam; sand, 40%; silt, 43%, clay, 17%; soil pH, 5.3; dry matter, 72%; moisture, 28%; organic matter, 9%. Ant hill counts were taken every week for 6 consecutive weeks.
