During the 1995 growing season several studies examining the efficacy and rate structure of Tracer^®; for control of cotton lepidopterous pests were conducted across the mid-South (Mississippi, Arkansas, Louisiana, Tennessee and Missouri). Results of these studies indicate Tracer, when used at labeled rates, provides equivalent or superior control for control of cotton bollworm, resistant tobacco budworm, armyworm and looper when compared to current control products. The use of Tracer for control of lepidopterous pests on cotton will provide the grower the opportunity to explore the use of IPM without a reduction in yield.
