Economics and incremental benefit cost ratio of novel insecticides against mustard aphid Lipaphis erysimi Kalt

Abstract

The effect of different novel insecticides treatment against mustard aphid was determined on the basis of seed yield and Incremental Benefit Cost Ratio. The treatment Dimethoate 30 EC (1 ml/lt) recorded significantly higher seed yield than other all treatments and followed by the treatment Imidacloprid 17.8 SL (0.25 ml/lt), Thiamethoxam 25 WG (0.20 g/lt), Acetamiprid 20 SP (0.1 g/lt), Clothianidine 50 WDG (0.12 g/lt), Verticillium lecanii (2 g/lt), Azadirachtin 3000 ppm (5 ml/lt) and Beauveria bassiana (2 g/lt). The Incremental Cost Benefit Ratio treatment Dimethoate 30 EC (1 ml/lt) was most economic, it gave the maximum benefit (1:15.4) as compare to remaining treatment all the treatment found as cost effective over the control.
