Cost benefit ratio were found highest in T4 Chlorantraniliprole 48% SC (1:3.42) followed by T6 Emamectin Benzoate 5% SG (1:3.31), T7 Flubendiamide 20WG (1:2.90), T3 Spinosad 45% SC (1:2.56), T1 NSKE 10% (1:2.51), T2 Neem oil 4ml/lit (1:2.41), T5 Indoxacarb 0.05% SC (1:2.26) and control T0 (1:1.80).
