An experiment was conducted on bioefficacy of newer and biorational insecticides against shoot and fruit borer on okra. Efficacy of insecticides tested against Earias spp on okra indicated that the minimum per cent infestation of shoot and fruit borer was found in the treatment of indoxacarb () followed by spinosad (), emamectin benzoate () and fipronil (). The acetamiprid, acephate, dimethoate/ malathion and NSKE registered , , and per cent infestation of shoot and fruit borer and existed in moderate group of efficacy. The treatments of B. bassiana with per cent infestation proved least effective followed by Btk (). |
