The field trial was conducted to evaluate the effect of different biopesticides against major insect pests of mustard at research farm of Department of Agricultural Entomology, College of Agriculture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, Maharashtra, India. The results revealed that Azadirachtin 10000 ppm, Beauveria bassiana, Lecanicillium lecanii and NSKE could be the best combination of treatments in management of major insect pests of mustard as Azadirachtin 10000 ppm and Beauveria bassiana had a superior control over aphids and larval populations, respectively and both were aptly assisted by Lecanicillium lecanii and NSKE. Considering the economics of treatments, Azadirachtin 10000 ppm (1:16.97) and Beauveria bassiana (1:13.50) were found more economical than other treatments.

Biopesticides, Azadirachtin 10000 ppm, Beauveria bassiana, mustard etc.

The results shown that Azadirachtin 10000 ppm assisted by Lecanicillium lecanii had better control over aphids whereas Beauveria bassiana followed by Lecanicillium lecanii had superiority in controlling the leaf webber and sawfly population. Both these materials are supported by NSKE. One can here clearly sees the best combination of treatments in managing the major insect pests by eco-friendly method. When it comes to the economics of treatments, Azadirachtin 10000 ppm (1:16.97) and Beauveria bassiana (1:13.50) were found more economical. As the world is concerned about climate change, global warming and environment pollution, we as an agriculture scientists need to look for alternative methods to conventional chemical applications. More of experiments are needed to evaluate these treatment materials in oil seed crops
