Results revealed that spinosad 60 g a.i. ha−1; emamectin benzoate 8 g a.i. ha−1 and Fipronil 100 g a.i. ha−1 found most effective in reducing pod damage and grain damage by M. vitrata and also showed increase in yield. However, highest net return was recorded from imidacloprid 50 g a.i. ha−1 followed by spinosad 60 g a.i. ha−1 and minimum in Verticillium lecanii (1 × 108 Spores g−1) 5 g L−1. The highest benefit: cost ratio was observed in imidacloprid 50 g a.i. ha−1, which was most efficient treatment followed by acetamiprid 20 g a.i. ha−1 and whereas, lowest in Verticillium lecanii (1 × 108 Spores g−1) 5 g L−1.
