Trunk smearing prevention and cure: the washing powder sold in ① market is 5 times as liquid and smeared evenly on the killed tree trunk. 5 parts of kerosene, 1 part of washing powder and 6 parts of water sold in ② were evenly smeared on the injured tree trunk. 5 parts of crude diesel oil and 1 part of washing powder and 6 parts of washing powder sold in ③ were evenly smeared on the trunk of the killed tree, and the control effect was very good. 3. Chemical control: choose the insecticides to kill scale insects and control the hatching period of the first generation of young scale insects in time (generally in the flowering stage of Sophora japonica in Beijing).
