Excellent systemic activity: Foliar tests show that its systemic activity (LC50) is 2-3 times that of pirimicarb and more than 140 times that of cypermethrin.
It can prevent and control resistant strains of pests such as peach aphids that are resistant to organophosphate and carbamate insecticides.
