Gaucho 480 (Imidacloprid) seed treatment insecticide was evaluated in 10 states across the southern region of the United States for its efficacy against early season insect pests in cotton. When averaged over all locations, Gaucho 480 at 8 fl oz./cwt reduced both adult and immature thrips, reduced thrips damage, and increased cotton yields when compared to the check (no insecticide). Gaucho was comparable to Temik in immature thrips control, thrips damage ratings, and cotton yields.
