Thrips Management with Gaucho Seed Treatment in North Carolina Cotton

John Van Duyn, J. R. Bradley, Jr., Amy L. Lambert, Charles P.-C. Suh and Joel Faircloth


Populations of thrips, aphids, and spider mites were monitored in seedling cotton treated with at-planting applications of Gaucho® seed treatment (8 oz/cwt. Seed) or Temik 15 G® (5 lbs/acre). Plant performance parameters were also monitored. In comparison, Gaucho showed short-term thrips control, favorable performance against cotton aphid, and a tendency to promote spider mites. Temik showed a better "earliness profile" (lower fruit set and more early opening bolls). In four tests yields were statistically superior vs the UTC for Gaucho and Temik but were the same for each other. However, Temik was always the highest yielding and averaged 89 pounds/acre more lint over the four studies.
