Field efficacy of different insecticides and bio-pesticides against okra jassid

Abstract

The experiment was conducted during 2018-19 at BTC CARS, Bilaspur (IGKV), Chhattisgarh to evaluate the insecticides and bio-pesticides against okra jassid under field condition. Two insecticides viz. Cartap hydrochloride 4 G @ 1kg a.i./ha, Fipronil 0.3 G @ 60g a.i./ha and three bio-pesticides viz. Beauveria bassiana @ 10g/lit., Bacillus thuringiensis @ 2g/lit., Metarhizium anisopliae @ 10g/lit. Fipronil 0.3 G soil application after the germination followed by spray with Beauveria bassiana was found to be most effective against okra jassid, as it was recorded overall less jassid population (1.62/plant). The maximum jassid population (2.89/plant) was recorded in Cartap hydrochloride 4 G soil application after the germination. Fipronil 0.3 G soil application after the germination followed by spray with Metarhizium anisopliae was recorded highest fruit yield (89.89q/ha) with benefit cost ratio 1.38:1.00.
