Bioefficacy of Certain Insecticides and Biopesticides against Spotted Pod Borer, Maruca vitrata Infesting Greengram

摘要

A filed study was conducted to evaluate the efficacy of certain insecticides and biopesticides for the management of Maruca vitrata on greengram during Xton/2014-15 and 2015-16. The data indicated that Spinosad 60g a.i./ha followed by Emamectin benzoate 8g a.i./ha were the most effective treatments in reducing M. vitrata larval population whereas Verticillium lecanii (1x10s Spores/g) 5g/L was observed to be the least effective treatment. Spinosad 60g a.i. /ha treatment produced maximum and Verticillium lecanii (1x10s Spores/g) 5g/L produced minimum yield during both the years of experimentation.
