Three separate tests were conducted during the 2000 cotton growing season at the Southeast Branch Experiment Station near Rohwer, AR to evaluate the efficacy of several new and traditional insecticides against cotton bollworm and tobacco budworm. Efficacy of insecticides was rated 3 days after treatment by examining 25 terminals, 25 squares, and 25 small bolls per plot and recording the number of worms and damaged parts. Tobacco budworm was the predominant heliothine species (> 90%) in all three tests. Thus, worm count and damage in plots treated with pyrethroids tended to be greater than in plots that received other treatments. Tobacco budworm was effectively controlled by the new insecticides Steward (0.11 lb ai/acre), Tracer (0.063 lb ai/ac), and Denim (0.01 lb ai/acre). Tracer (0.063 lb ai/acre) was as effective in reducing worm count and damage as a tank mix of Lorsban (0.5 lb ai/acre) + Tracer (0.031 lb ai/acre). Steward, Tracer, and Denim (all rates) provided a significant increase in lint yield compared to the check treatment. Lint yields in plots treated with pyrethroids, when used alone, were similar to those of the untreated check plots.
