Abstract

Field trial was conducted during rabi season 2022-2023 at Central Research Farm (CRF) , SHUATS. The experiment was laid out in Randomised block design with eight treatments each replicated thrice using a variety Green Soccer (546). The treatments are T1 Chlorantraniliprole 18.5 % SC, T2 Indoxacarb 14.5% SC, T3 Flubendiamide 39.3 SC, T4 Bacillus thuringeninsis (1x108 CFU/ml), T5 Metarhizium anisiopilae (1x108 CFU/ml), T6 NSKE 5%, T7 Spinosad 45% SC and along with an untreated T8 control against Plutella xylostella in Cabbage. Mean reduction in the larval population of Diamond back moth per plant revealed that all treatments significantly superior over control (4.200). Among all the treatments T1 Chlorantraniliprole 18.5 % SC recorded highest larval reduction with mean (1.000) of Plutella Xylostella followed by T2 Indoxacarb 14.5% SC (1.178), T7 Spinosad 45% SC (1.311), T3 Flubendiamide 39.3 SC (1.322), T5 Metarhizium anisiopilae (1x108 CFU/ml) (1.456), T4 Bacillus thuringeninsis (1x108 CFU/ml) (1.522) and T6 NSKE 5% (1.734) and least recorded in T8 control (4.200). Highest yield 336 q/ha as well as B:C ratio (1:5.35) was obtained from the treatment Chlorantraniliprole 18.5% SC followed by T2 Indoxacarb 14.5% SC (1:5.28), T7 Spinosad 45% SC (1:4.85) T3 Flubendiamide 39.3 SC (1:4.83), T5 Metarhizium anisiopilae (1x108 CFU/ml) (1:4.18), T4 Bacillus thuringeninsis (1x108 CFU/ml) (1:4.71) and T6 NSKE 5% (1:3.52) superior over the control (1:2.87).
