Efficacy of insecticides against larval population of defoliators of soybean

Abstract

An experiment was conducted during 2018-19 and 2019-20 at Regional Sugarcane and Rice Research Station, Rudrur, to assess the chemical control of soybean pests, using popular insecticides viz., Acephate, Monocrotophos, Quinalphos, Triazophos, Profenophos, Thiodicarb, Chlorantraniliprole, Emamectin benzoate, Thiamethoxam+ Lambda cyhalothrin and were compared with untreated control using Randomized Block Design with three replications. Significant differences were noticed among all treatments. Emamectin benzoate 5.0% SG @ 0.4 g/l was found effective against defoliators followed by Chlorantraniliprole 18.5% SC @ 0.3 ml/l.
