Abstract:
The present experiment was undertaken at central research field, SHUATS, Prayagraj, Uttar Pradesh, India during kharif season, 2021, Eight treatments including control viz, Beauveria bassiana (T₁), NPV (T₂), NSKE 5% (T₃), Emamectin Benzoate 5SG (T₄), Chlorantraniliprole 18.5SC (T₅), Spinosad 45%SC (T₆), Flubendamide 480SC (T₇) and untreated Control (T₀) in RBD with three replications were evaluate against spotted pod borer, Maruca vitrata. The mean larval reduction of greengram pod borer Maruca vitrata on third, seventh and fourteen days after spraying revealed that the treatments Beauveria bassiana (T₁) (1.685), NPV (T₂) (2.022), NSKE 5% (T₃) (1.788), Emamectin Benzoate 5SG (T₄) (1.288), Chlorantraniliprole 18.5SC (T₅) (0.933), Spinosad 45%SC (T₆) (1.555), Flubendamide 480SC (T₇) (1.344) were found superior over all the treatment first and second sprays respectively. Insecticide Chlorantraniliprole 18.5SC (T5) (0.933) gave maximum larval mean reduction followed by Emamectin Benzoate 5SG (T4) (1.266). When cost benefit ratio was worked out, interesting result was achieved. Among the treatments studied, the best and most economical treatment was Emamectin Benzoate 5SG (1:2.94) followed by Chlorantraniliprole 18.5SC (1:2.86), Flubendiamide 20SG (1:2.68), Spinosad 45SC (1:2.23), Beauveria bassiana (1:2.06), NSKE 5% (1:1.83) and NPV (1:1.59), as compared to control plot (1:1.08).
