Abstract

The research trial was undertaken at Central Research Field, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. Experiment was laid in RBD with three replication consists of eight treatments viz, Emamectin benzoate 5% SG (0.4 gm/lit), Chlorantraniliprole 18.5% SC (0.5 ml/lit), Novaluron 10% EC (2 ml/lit), Spinosad 45% SC (0.5 ml/lit), Beauveria bassiana 1.15% WP (1 gm/lit), Neem oil 1% (10 ml/lit), Karanj oil 2% (20 ml/lit) and untreated control. The mean larval population of diamondback moth (Plutella xylostella) on cabbage at 3rd, 7th, and 14th days after two sprays revealed that the treatment Chlorantraniliprole 18.5% SC (2.63) observed the lowest population of diamond back moth followed by Spinosad 45%SC (2.96), Emamectin benzoate 5% SG (3.02), Novaluron 10% EC (3.32), Beauveria bassiana 1.15% WP (3.54), Neem oil 1% (3.70) and Karanj oil2% (3.85) as compared to control (5.45). Among the treatments studied, the best and most economical treatment was Chlorantraniliprole 18.5 %SC with 245.52 q/ha yield and cost benefit ratio (1:6.53),     followed by Spinosad 45% SC 230.15 q/ha with (1:6.04) C:B ratio, Emamectin benzoate 5% SG 190.30 q/ha with (1:5.54) C:B ratio, Novaluron 10% EC 170.20 q/ha with (1:4.67) C:B ratio, Beauveria bassiana 1.15%WP 150.35 q/ha with (1:4.40) C:B ratio, Neem oil 1% 142 q/ha with (1:3.85) C:B ratio and Karanj oil 2% 135.45 q/ha with (1:3.68) C:B ratio and Control 65.20 q/ha (1: 1.97) C:B ratio.
