Bioefficacy of newer insecticides against tomato fruit borer, Helicoverpa armigera (Hubner) on tomato, Lycopersicon esculentum (mill) under protected cultivation

Abstract

For tomato fruit borer management seven newer insecticides were taken viz., spinosad 45% SC, chlorantraniliprole 18.5% SC, emamectin benzoate 5% SG, indoxacarb 14.5% SC, cyantraniliprole 10.26% OD, spinatoram 11.7% SC and flubendiamide 39.35% SG. The total three numbers of sprays were done. The treatment Chlorantraniliprole 18.5% SC, Flubendiamide 39.35% SG, Emamectin benzoate 5% SG, Indoxacarb 14.5% SC and Spinatoram 11.7 SC% was significantly at par with each other. Among them chlorantraniliprole 18.5% SC found most effective than all other treatment. The descending order of efficacy was recorded in all three sprays as chlorantraniliprole 18.5% SC > flubendiamide 39.35% SG > emamectin benzoate 5% SG > indoxacarb 14.5% SC > spinatoram 11.7% SC > cyantraniliprole 10.26% OD > spinosad 45% SC.
