N2  - Cabbage is Ethiopia's second most important vegetable crop in production next to red pepper. It is a widely grown vegetable throughout the world. A synthetic insecticide Dedu Star 35% SC and Range 5% EC insecticides was tested under field conditions at three different locations. The experiment was laid out in a Randomized Complete Block Design with three replications on farmers' fields to evaluate the performance of newly introduced insecticide to control Cabbage aphids in Cabbage crops. The effect of two insecticides in three different rates on the percent mortality of Brevicoryne brassicae was assessed at West Shoa on farmers' fields at Ambo, Toke Kutaye, and Ejersa lafo districts from January 2021 to May 2021. Closer 240 SC (Sulfoxaflor) and water were included as a standard check and untreated control. At all locations, the highest rate of Dedustar was 35% SC (225 ml/ha), and Range 5% EC (375 ml/ha) showed high mortality rates and a low number of aphid infestations.  The best treatment was 99.13, 98.2,5%, and 96.13% mortality at Ambo, Toke kutaye, and Ejersa lafo, respectively. The yield loss recorded in the control treatment was 61.37, 64.01, and 52.32 at Ambo, Toke kutaye, and Ejersa lafo, respectively. From the experiments, it can be concluded that both new insecticides Dedustar 35% SC and Range 5% EC at a maximum rate compatible with the management of cabbage aphids.
