Evaluation of biopesticide for management of insect-pests complex with safety to natural fauna on mustard

摘要

Field experiments were conducted in six locations at farmer's fields of Sonkutch and Bagli block in Dewas district to evaluate the performance of biopesticides, Metarhzium anisopliae including other components (IPM field) against insect-pests and naturalenemies in mustard. Results revealed that the IPM held proved to be effective with lowest incidence of major insect-pests viz., aphid (Lipaphis erysimi), sawfly (Athalia lugens proximo), painted bug (Bagrada cruciferarum) and leaf miner (Phytomyza horticol) with higher grain yield and monetary benefit as compared to Non IPM field. The maximum yield was recorded in IPM (15.28q/ha) than Non IPM (13.23 q/ha) field. The IPM field was ultimately the promising one with better net returns (Cost benefit ratio
