Abstract

A filed study was conducted to evaluate the efficacy of certain insecticides and biopesticides for the management of Maruca vitrata on greengram during Kharif 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 (1×108 Spores/g) 5g/L was observed to be the least effective treatment. Spinosad 60g a.i./ha treatment produced maximum and Verticillium lecanii (1×108 Spores/g) 5g/L produced minimum yield during both the years of experimentation.

Spinosad 60g a.i./ha and Emamectin benzoate 8g a.i./ha were the most effective treatments and significantly superior than the other treatments

Verticillium lecanii (1×108 Spores/g) 5g/L was the least effective treatment

Maximum yield was obtained from Spinosad 60g a.i./hatreated plots
