Author(s): Babita Bhatt, AK Karnatak and Shivashankara
Abstract: Field experiment was conducted during kharif 2016 to evaluate the efficacy of six insecticides viz. carbofuran 3% CG, thiamethoxam 25% WG, chlorantraniliprole 18.5% SC, quinalphos 25% EC, buprofezin 25% SC and cypermethrin 25% SC against leafhopper prevailing in okra agroecosystem. Among all the treatments thiamethoxam 25%WG @ 25 g a.i./ha was found to be most effective against leafhopper (71.67% and 72.59% reduction over control after first and second spray, respectively) this was followed by buprofezin 25% SC @ 200 g a.i./ ha and quinalphos 25%EC @ 200 g a.i./ha while carbofuran 3% CG @ 1000 g a.i./ha was least effective among all. Similarly, chlorantraniliprole 18.5% SC @ 25 g a.i./ha treated plot gave the maximum yield.
