The invention relates to a slow-release pesticide band for controlling woolly apple aphid and a method for the same. The pesticide band comprises a belt-shape permeable membrane which is coated or sprayed with feldene powder, wherein the feldene powder is prepared by mixing imidacloprid with thiamethoxam according to mass ratio of 1:(0.25-4). The control method comprises the following steps of: digging surface soil at the root neck of a trunk for 4-6cm; then laying the slow-release pesticide band at the root neck for a circle; restoring the surface soil; quantitatively watering the root neck of each plant by 1-2 liters; and enabling effective components of the pesticide to seep a pesticide membrane along with water current, to be absorbed by bark and flow to each part of a tree body along with a plant liquid in a sieve tube. According to the slow-release pesticide band disclosed by the invention and powdery pesticide is packaged in the pesticide band, is laid to the root neck of the tree body; effective components of pesticide are slowly seeped into the bark by watering or rainfall wetting and are conducted to each part of the tree body along with a phloem part. The method has the advantages of concentrated pesticide application, continuous slow release, continuous control action on the pests, simpleness and convenience for operation, favorable control effect and lower pollution to the environment than that of chlorpyrifos spray.
