ABSTRACT

Thrips continued to be an early-season pest in Southeast Arkansas cotton during 2002. Cold, wet conditions during a critical 2-week period following planting, coupled with heavy thrips populations, resulted in pronounced stress on seedling cotton. Evaluation of newer seed treatments along with an existing standard in-furrow treatment on several different varieties demonstrated that thiamethoxam (Cruiser seed treatment) provided the best control of thrips and the highest yields. In a second trial, only Temik at 4 lb per acre provided significantly better control than the untreated control across sample dates.
