Efficacy of newer insecticides against tur plume moth, Exelastis atomosa (Walsingham) on pigeonpea

Abstract

The present study entitled, “Efficacy of newer insecticides against tur plume moth, Exelastis atomosa (Walsingham) on pigeonpea” was carried out at the Research Farm of Pulses Improvement Project, MPKV, Rahuri during the season kharif 2024. There were eight treatments viz., emamectin benzoate 5% SG, indoxacarb 14.50% SC, chlorantraniliprole 18.50% SC, lambda-cyhalothrin 5% EC, spinosad 45% EC, thiamethoxam 25% WG, acetamiprid 20% SP and untreated control. Studies on efficacy revealed that, chlorantraniliprole 18.50% SC @ 0.3 ml/L was superior treatment with minimum larval population of 0.29 larvae/plant and it was followed by indoxacarb 14.50% SC @ 0.7 ml/L (0.62 larvae/plant) and emamectin benzoate 5% SG @ 0.4 g/L (0.72 larvae/plant) which were at par with each other. The results of pod and grain damage due to tur plume moth on pigeonpea revealed that plot treated with chlorantraniliprole 18.50% SC @ 0.3 ml/L was superior in reducing pod and grain damage to lowest level of 1.90 and 1.03% respectively as compared to other treatments. The maximum grain yield was obtained from the plots treated with chlorantraniliprole 18.50% SC @ 0.3 ml/L (21.80 q/ha). Highest ICBR (1:6.70) was obtained from the treatment with emamectin benzoate 5% SG @ 0.4 g/L followed by indoxacarb 14.50% SC @ 0.7 ml/L (1:5.96) an chlorantraniliprole 18.50% SC @ 0.3 ml/L (1:5.60).
