Experimentation was done to observe the efficacy of some insecticides against shoot and fruit borer, Earias vittella (Fabricius) of okra during kharif season 2016 at the Horticulture farm, Department of Horticulture, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya (IGKV) Raipur, Chhattisgarh.

BAS 450 01 I 300 SC @12.5g.a.i./ha (16.33%) and BAS 450 01 I 300 SC @6.5g.a.i./ha (18.74%) was found statistically on par with each other, followed by Cypermethrin 10% EC @ 70g.a.i./ha (21.14) Maximum healthy fruit yield recorded from the treatment BAS 450 01 I300 SC @18.5g.a.i/ha (155.99 q/ha), followed by Chlorantraniliprole18.5% SC @25g.a.i/ha (155.10q/ha), Cypermethrin 10% EC@70g.a.i./ha (154.99q/ha). | Assessment of yield losses due to shoot and fruit borer, Earias vittella (Fab.) in okra
