Efficacy of newer combination insecticides against shoot and fruit borer, Earias vittella (Fabricius) on okra

An experiment was conducted to evaluate the efficacy of newer combination insecticides against shoot and fruit borer, Earias vittella (Fabricius) on okra. Among tested insecticides, indoxacarb 14.5 SC + acetamiprid 7.7 SC @ 400 ml/ha, profenophos 40 EC + cypermethrin 4 EC @1000 ml/ha and chlorpyriphos 50 EC + cypermethrin 5 EC @1000 ml/ha found to be the most effective in reducing the fruit infestation on number basis as well as weight basis was 15.65 to 14.80 and 16.25 to 15.24%, respectively as against 32.14 and 31.31%in the control. The significantly highest yield (124.44 q/ha) of healthy fruits was recorded in indoxacarb 14.5 SC + acetamiprid 7.7 SC followed by profenophos 40 EC + cypermethrin 4 EC (114.52 q/ha) and chlorpyriphos 50 EC + cypermethrin 5 EC (112.70 q/ha). The highest incremental benefit cost ratio (12.45) was registered by indoxacarb 14.5 SC + acetamiprid 7.7 SC followed by profenophos 40 EC + cypermethrin 4 EC (11.07) and chlorpyriphos 50 EC + cypermethrin 5 EC (9.66).
