Eight insecticidal treatments (including insect growth regulators) were evaluated against aphids (Aphis gossypii Glover) and thrips (Thrips tabaci Lindeman) in Bt cotton. The results revealed that buprofezin 25%SC proved effective in minimizing the A. gossypii. However, it was found at par with pyriproxyfen 10%EC. Buprofezin 25%SC also led to minimum number of T. tabaci and was found at par with pyriproxyfen 10%EC, buprofezin 25%SC+ NSKE 5%, pyriproxyfen 10%EC+ NSKE 5% and NSKE 5%. No deleterious effect of these were observed on the natural enemies. Maximum seed cotton yield was obtained with buprofezin 25%SC and it proved to be the economically viable with ICBR of 1: 6.6.Keywords
