A field experiment was conducted to evaluate the efficacy of certain new molecules as well as entomopathogens as foliar sprays against leafhoppers in Bt cotton at Regional Agricultural Research Station, Lam, Guntur, Andhra Pradesh for two consecutive years. The new molecule, flonicamid 50% WG at two doses i.e. at 75 g a.i./ha and 100g a.i./ha followed by diafenthiuron 50% WP 300 g a.i./ha and buprofezin 25% SC @ 250 g a.i./ha were found promising against leaf hoppers together with high seed cotton yield. New molecules were found significantly superior over to NSKE 5 % and entomopathogens in suppressing the leafhoppers.
