Abstract

The field experiment was conducted during Kharif season of 2013 to study the Efficacy of Entomopathogenic fungi against Jassids on okra. During the course of present investigation, three entomopathogenic fungi were tested for their effect at various combinations with each other at same concentrations and compared with chemical insecticide dimethoate 30EC, with a view to find out most effective treatment (s) on Jassids on okra. The experiment was conducted at P.G. Research Farm of Agril. Entomology Department, Mahatma Phule Krishi Vidyapeeth, Rahuri. The influence of different biopesticides and their combinations on Jassids was studied during the investigation. Thus, the results indicated that combination of entomopathogenic fungi as V. lecanii 1.15 % WP + M. anisopliae 1.15 % WP was the most effective treatment as compared to standard check dimethoate for suppression of jassids population on okra.
