The bio-efficacy of five insecticidal spray schedules against painted bug, Bagrada hilaris Burmeister in mustard was evaluated. The field experiment was conducted at Instructional Farm, College of Agriculture, JAU, Junagadh (Gujarat) during rabi 2012-13 and 2013-14. The results revealed that schedule 4 consisting of flonicamid 50 WG @ 0.02 per cent at seedling stage, flubendiamide 480 SC @ 0.014 per cent at pre-flowering stage, azadirachtin 1500 ppm @ 0.15 per cent at 50% flowering stage and acephate 25 + fenvalerate 3 EC @ 0.028 per cent at 50% pod formation stage was significantly. Superior treatment which recorded highest per cent mortality (74.58) over stage of the crop and year, whereas the schedule S₁ (71.75 per cent mortality) proved next better effective schedule against mustard painted bug. The highest grain yield was found in schedule S₄ (1302 kg/ha) followed by S₃ (1218 kg/ha) and S₅ (1172 kg/ha). The lowest grain yield was recorded in untreated control schedule S₆ (500 kg/ha). The highest net realization was found in schedule S₄ (29674 Rs/ha) followed by schedule S₃ (26566 Rs/ha). The schedule S₂ generated highest ICBR ratio (1:6.7) followed by schedule S₃ (1:6.3) and schedule S₄ (1:6.3) whereas, schedule S₁ (1:3.1) gave significantly lower ICBR than other schedules. Thus, schedule S₂ (imidacloprid 17.8 SL + indoxacarb 14.5 SC + L. lecanii @ 2.0 kg/ha and triazophos 35 + deltamethrin 1 EC) and S₃ (thiamethoxam 25 WG + emamectin benzoate 5 WG + N. rileyi @ 2.5 kg/ha and chlorpyriphos 16 + alphamethrin 1 EC) can be suggested for the effective and economical management of mustard painted bug.
