The field was laid in Randomised Block Design with eight treatments viz., Spinetoram 11.7%SC, Chlorantraniliprole 18.5%SC, Flubendiamide 39.35%SC, Emamectin benzoate 5%SG, Neem oil 2%, NPV, Novaluron 10%EC along with control plot. First and second spray were carried with 15 days interval, the results revealed that, among the different treatments Spinetoram 11.7%SC, (8.06 and 4.93) was most effective treatment over controlfollowed by Chlorantraniliprole 18.5%SC (9.33 and 6.24), Flubendiamide 39.35% SC (9.53 and 6.42), Emamectin benzoate 5%SG (10.06 and 6.90), Novaluron 10%EC (11.33 and 8.13), NPV (11.46 and 8.28) and Neem oil 2% (11.53 and 8.37). Among the treatments studied, the best and most economical treatment was Spinetoram 11.7%SC (1:1.79), followed by Chlorantraniliprole 18.5%SC (1:1.78), Flubendiamide 39.35%SC (1:1.77), Emamectin benzoate 5%SG (1:1.74), Novaluron 10%EC (1:1.68), NPV (1:1.60) and Neem oil 2% (1:1.44) when compared to control plot (1:1.25).
