Abstract/Contents:"Granular formulations of bifenthrin 0.05G (0.05, 0.1, 0.2 and 0.4 lb (AI)/acre and the commercial product, Talstar 0.2G (0.1, 0.2 and 0.4 lb (AI)/acre), were compared with treatments of chlorpyrifos (Dursban) 1G (1 lb (AI)/acre) and diazinon 5G (4.4 lb (AI)/acre)for control of red imported fire ant colonies. Whole plots (500-700 ft², with a mean of 8 active colonies/plot) of infested turfgrass were treated on 7 Aug. 1996 with a walk behind drop spreader. All treatments of bifenthrin and Talstar provided increasingly better control in time from 2 to 6 wk, with the highest rate (0.4 lb) of bifenthrin 0.05G providing 92.9% and Talstar 0.02G providing 100% control by 6 wk after treatment. With each formulation, control increased as the rate increased. All chemical treatments including Dursban and diazinon, were significantly better than the untreated check by 6 wk. Also, the high (0.4 lb) rates for bifenthrin and Talstar, and the Dursban (1 lb) and diazinon (4.4 lb) treatments each reduced the foraging activity to zero within 3 d after treatment. By 6 wk, no difference was recorded for foraging activity in plots treated with either the highest rate (0.4 lb) of Talstar or bifenthrin, or in the Dursban plots, but each had significantly less foraging ants than in the diazinon plots. Foraging activity for ants within a plot was assayed by placing 3 hot dog baited traps near the central area of the plot for ca. 30 min exposure and counting the ants collected. Mound mortality was determined by stomping on the soil near the mound and observing the ant activity."
