Present study revealed that the highest aphid mortality was achieved with thiamethoxam 25 WG at 0.5 g/L of water, showing mortality rates of 78.64, 85.63, 88.34 and 91.83% at 1, 3, 7, and 10 days after spraying (DAS), respectively followed by thiacloprid 21.7 SC at 0.4 ml/L of water, with mortality rates of 72.75, 77.77, 82.76 and 87.30% at the same intervals. Dimethoate 30 EC at 1 ml/L of water showed mortality rates of 72.47, 74.95, 78.64 and 83.57% at 1, 3, 7, and 10 DAS, respectively. The highest yield was recorded in plots treated with thiamethoxam 25 WG (27.22 t/ha), followed by thiacloprid 21.7 SC (25.33 t/ha), while the control plots treated with water had the lowest yield (8.92 t/ha) during the kale growing season.
