Abstract A field experiment conducted evaluated the efficacy of chlorantraniliprole 18.5SC @ 100 ml/ha, indoxacarb 15.8 SC @ 300 ml/ha, quinalphos 25 EC @ 1500 ml/ha, triazophos 40 EC @ 800 ml/ha, thiacloprid 21.7 SC @ 650 ml/ha and one botanical, neem oil @ 3 lit/ha against major pests of soybean. Among these, thiacloprid 21.7 SC was found tobe the most effective against flea beetle, Monolepta signata; quinalphos 25 EC against the tobacco caterpillar Spodoptera litura (F.) and blister beetle Mylabris phalerata Thunb; chlorantraniliprole 18.5SC against stem fly Ophiomyia phaseoli Tryon; and chlorantraniliprole 18.5SC and thiacloprid 21.7 SC against leaf folder Nacoleia vulgalis Guenee. The highest yield was obtained with thiacloprid 21.7SC treatment.
