Effect of different treatment modules for insect management of soybean

Abstract

The present investigation carried out in kharif season of year 2023 on field of Oilseed Research Unit, Dr. PDKV Akola. Research plot treated with seed treatment of Azoxystrobin 2.5% + Thiophanate Methyl 11.25% + Thiomethoxam 25% FS @ 10 ml/kg of seed before sowing. This experiment carried out in eight treatment modules and three replications. Amongst all treatment modules tested, the most promising treatment module found was M1 (Indoxacarb 15.80% followed by Chlorantraniliprole 9.30% + lambda cyhalothrin 4.60% ZC (combi prod) + Propiconazole 25% EC) for control of stem fly (1.51%), girdle beetle (1.21%) and semilooper (1.09 larvae/ml) in soybean. These results translate into yield. And the best module obtained in terms of yield M3 (Chlorantraniliprole 18.5% SC followed by Thiamethoxam 12.60% + Lambda- cyhalothrin 9.50% ZC + Propiconazole 25% EC) recorded 23.71 q/ha yield, which statistically similar with treatment module M1 (Indoxacarb 15.80% EC followed by Chlorantraniliprole 9.30% + lambda cyhalothrin 4.60% ZC + Propiconazole 25% EC) recorded yield 22.22 q/ha yield. The highest ICBR was obtained in treatment module M3 (1:12.09), followed by treatment module were M4 (1:9.27) and M1 (1:9.09).
