Abstract:
An experiment was conducted to evaluate different insecticides as seed treatment against fall armyworm, Spodoptera frugiperda infesting fodder maize. Among the tested insecticides, cyantraniliprole 19.8 + thiamethoxam 19.8 FS @ 6 ml/kg of seed was significantly superior to rest of the treatments in reducing the FAW (1.32 larvae/20 plant). Seed treatment with cyantraniliprole 19.8 + thiamethoxam 19.8 FS @ 6 ml/kg of seed was recorded significantly lower plant damage (29.97%). Maximum plant damage (%) was registered in plot having seed treatment with fipronil 5 SC @ 6ml/kg of seed (61.72%), fipronil 5 SC @ 8ml/kg of seed (61.64%), thiamethoxam 30 FS @ 6 ml/kg of seed (59.99%) and imidacloprid 600 FS @ 6 ml/kg of seed (58.30%). The highest green fodder yield (633 q/ha) was obtained from the plot having seed treatment of cyantraniliprole 19.8 + thiamethoxam 19.8 FS @ 6 ml/kg of seed.
