Abstract:
The field experiment was undertaken at SHUATS central research field, Prayagraj, Uttar Pradesh, India during kharif, 2021 containing seven treatments viz, Triazophos 40% EC (T1), Chlorantraniliprole 18.50% SC (T2), Spinosad 45% SC (T3), Azadirachtin 0.03% EC (T4), lambda cyhalothrin 5% EC (T5), Azadirachtin 14.5% SC (T6) Flubendiamide 39.35% SC (T7), control (T0) in RBD with three replications aiming to evaluate their efficacy of selected insecticides against pod borer, Maruca vitrata. Data was taken on black gram pod with number of larvae per infested pod and calculated larval mean reduction. The mean larval reduction of black gram pod borer Maruca vitrata on third, seventh and fourteen days after spraying revealed that the treatments Triazophos 40% EC (T1), Chlorantraniliprole 18.50% SC (T2), Spinosad 45% SC (T3), Azadirachtin 0.03% EC (T4), lambda cyhalothrin 5% EC (T5), Indoxacarb 14.5% SC (T6) Flubendiamide 39.35% SC (T7), were found superior over all the treatment first and second sprays respectively. Flubendiamide 39.35% SC (T7) gave maximum larval mean reduction followed by Chlorantraniliprole 18.50% SC (T4). When cost benefit ratio was worked out, interesting result was achieved. Among all the treatments, the best and most economical treatment was Flubendiamide 39.35% SC (T7) (1:2.77) followed by Chlorantraniliprole 18.50% SC (T4). (1:2.44).
