Four replications of 5 treatments were applied to a bluegrass fairway in 140-ft2 plots on 23 Jun, with a 1-ft buffer separating each plot. Plots were arranged in a RCB design. All treatments were applied with a 2-wheel bicycle sprayer equipped with 4 spray heads fitted with an 8005 flat fan-type noz zle and a 50-mesh stainer. The insecticides were applied by CO2 pressure at 40 psi. The volume of water and insecticide mix per plot was 2 gal/1000 ft2 Weather conditions were as follows: air temp, 77°F (6:00 pm); sky, scattered clouds.
