The present investigation entitled “Efficacy of chemicals insecticides and botanicals in the management of Diamondback moth (Plutella xylostella) in cabbage” cultivar i.e. Golden acer was conducted during November, 2015 to March, 2016 at Agricultural research farm, SHIATS, Allahabad. The occurrence of, Diamondback moth (Plutela xylostella) in 2015-2016 rabi season commenced from 6th standard week (February second week) with an average 0.25 larvae/plant. The Diamondback moth population increased and gradually reached peak level of 3.40 larvae/plant at 13th standard week (March last week). There after declined trend was observed. The percentage reduction of Diamondback moth (Plutella xylostella) on cabbage damage percent revealed that the maximum reduction per cent of Spinosad 45 SC recorded highest reduction of Diamondback moth population i.e. (49.45)% which was significantly superior over control followed by Indoxacarb 14.5% SC (45.305), Cypermethrin 5% EC (44.215), Emamectin benzoate 5% SG (42.78), Profenophos 50% EC (40.975), Neem Seed Kernal extract (39.195), Neem oil (39.705) was least effective among all the treatments respectively. The highest yield was recorded in Spinosad 45% SC (187.60 q/ha), followed by Indoxocrab 14.5%SC (178.25 q/ha), Cypermethrin 10 EC (175.48 q/ha), Emamectin benzoate 5%SG (173.75 q/ha), Profenophos 50% EC (165.24 q/ha), Neem oil (157.38 q/ha), NSKE 5% (152.61 q/ha), as compared to untreated check (80.24 q/h).
