The most effective was spinosad followed by novaluron. Bacillus thuringiensis was found least effective but it was significantly superior over control. The maximum cost: benefit ratio 1: 8.50 was recorded in novaluron with increase in yield of 47.3 q/ha followed by carbosulfan with 1:7.34 cost benefit ratio.
