Evaluation of Thrips Management Options in Cotton

Donald R. Johnson, John D. Hopkins, Gus M. Lorenz, III and Jack D. Reaper, III


 
ABSTRACT

Thrips are early-season pests that have the potential of causing 50-60% yield reduction in Arkansas cotton with the level of damage varying from year to year. The objective of this experiment was to evaluate seed treatment, in-furrow, and foliar insecticides for thrips management in cotton. Experiments were conducted in Lonoke Co. and Lee Co., AR, in 1999 and 2000, respectively. Thrips samples and ratings were taken at weekly intervals four times each year early in the growing season. In both years, all treatments significantly improved thrips control above that of the untreated check. In 1999, the Temik treatments outperformed the others with respect to thrips suppression, visual damage rating, and cotton yield. While thrips suppression was not significant among treatments in 2000, the Temik treatments achieved higher yields. The data presented from these growing seasons indicate Temik to be one of the best treatments for thrips control in Arkansas cotton.
