The present experiment was undertaken to study the “Efficacy of newer group of insecticides against whitefly on okra, Abelmoschus esculentus L. (Moench) during Kharif season 2018 at the vegetable research farm, B.H.U., Varanasi. The experiment consisted nine treatments including control. Concerning the efficacy of insecticides it was observed that Indoxacarb 14.5% + Acetamiprid 7.7% SC @ 72.5 + 38.5 g a.i ha–1 was found to be very effective against whiteflies followed by Indoxacarb14.5% + Acetamiprid 7.7% SC @58+30.8 g a.i ha–1 and Acetamiprid 20% SP @ 38.5 g a.i ha–1 while Cypermethrin 10% EC @ 600 g a.i ha–1 found least effective after the 3rd insecticide spraying. Whereas, rest of treatments like Indoxacarb 14.5% SC @ 72.5 g a.i ha–1, Chlorpyrifos 50% + Cypermethrin 5% EC@500+50 g a.i ha–1, Chlorpyrifos 50% EC @ 600 g a.i ha–1, Chlorpyrifos 50% + Cypermethrin 5% EC 375+37.5 g a.i ha–1 and Fenpropathrin 30% EC @ 100 g a.i ha–1showed moderate efficacy against whitefly.
