The present investigation entitled “Field efficacy of certain insecticides against shoot borer Earias vittella (Fabricius) on Kharif season okra in Prayagraj (U.P.)” cultivar i.e. VRO-6 was conducted during July to November 2019 at Central Research Farm, SHUATS, Naini, Prayagraj.
Two applications of seven insecticides viz; Spinosad 45% SC, Metarrhizium anisopliae, Verticillium lecani, Beauveria bassiana, Neem oil 3%, karanjin 2% EC, Aloevera extract 1%, were evaluated against shoot and fruit borer, Earias vittella. Minimum percent of shoot infestation, percent fruit infestation and B:C ratio were observed in Spinosad 45% SC with (5.22%, 5.86% and 1:11.1) respectively which was followed by Beauveria bassiana (11.63%, 12.33% and1:8.43) Verticillium lecani (16.81%, 15.51%, and 1:7.78) <Metarrhizium anisopliae (17.44%, 16.06% and 1:7.58)
