Abstract

Foliar pesticide spray schedule against mustard sawfly, Athalia lugens proxima (Klug.) is reported under field conditions at Junagadh, Gujarat during rabi 2012–13 and 2013–14. Schedule 3 (consisting of thiamethoxam 25 WG @ 0.006% at seedling stage, emamectin benzoate 5 WG @ 0.0025% at pre-flowering stage and Nomuraea rileyi @ 2.5 kg per ha−1 at 50% flowering stage) was superior in causing mortality to sawfly up to 69.63 per cent while the Schedule 4 (flonicamid 50 WG @0.02%, 20–25 DAS, flubendiamide 480 SC @0.014%, 40–55 DAS, azadirachtin @300 ppm, 60–65 DAS, combi-product of acephate 25% and fenvalerate 3% EC @0.028%, 70–75 DAS) was the next best (66.84% mortality). However, the grain yield was the highest in Schedule 4 (1302 kg per ha−1), followed by Schedule 3 (1218 kg per ha−1) and schedule 5 (1172 kg per ha−1), as compared to control (Schedule 6, 500 kg ha−1). The highest net realization was found in Schedule 4 (Rs. 29674 ha−1) followed by schedule 3 (Rs. 26566 ha−1). Schedule 2 showed the highest ICBR ratio (1: 6.7) followed by Schedule 3 (1: 6.3) and Schedule 4 (1: 6.3), whereas Schedule 1 (1: 3.1) gave significantly lower ICBR ratio than the other schedules. The Schedule 4 seems to have the overall potential for adoption.
