Online published on 21 July, 2020. Abstract The efficacy of five insecticidal spray schedules against leaf webber Crocidolomia binotalis (Zeller) in mustard was evaluated. The results revealed that schedule 3 consisting of thiamethoxam 25 WG @ 0.006% at seedling stage, emamectin benzoate 5 WG @ 0.0025% at pre-flowering stage, Nomuraea rileyi @ 2.5 kg/ha at 50% flowering stage and chlorpyriphos 16% + alphamethrin 1% EC @ 0.055% (S3) at 50% pod formation stage were superior. The schedule S4 (flonicamid 50 WG + flubendiamide 480 SC + azadirachtin 1500 ppm + acephate 25 + fenvalerate 3 EC) proved to be the next best. The maximum yield was obtained with this schedule. Schedule S2 (imidacloprid 17.8 SL + indoxacarb 14.5 SC + Lecanicillium lecanii @ 2.5 kg/ha and trizophos 35 + deltamethrin 1 EC) and S3 (thiamethoxam 25 + emamectin benzoate 5 WG + N. rileyi @ 2.5 kg/ha and chlorpyriphos 16 + alphamethrin 1 EC) could be suggested against mustard leaf webber.
