The invention discloses a perfusion method for preventing diseases and insect pests in a tree. The method includes the steps of insecticide preparation, hole drilling, insecticide application, hole sealing and the like. Firstly, 1500-2000 parts by weight of water, 3-6 parts by weight of pyrethroid insecticide, 3-6 parts by weight of organic phosphorus insecticide and 1-3 parts by weight of hydrolytic enzyme are mixed evenly and reserved. Perfusion holes are drilled on the trunk more than 3m away from the ground at the angle of 40-50 degrees in inclined downward mode, hole diameter is 6-8mm, hole depth is 4-5cm, one hole is drilled if diameter at breast height of a tree is <=5cm, one more hole is drilled if each 5cm is increased in the diameter of breast height, and the holes are intersects, rise in a spiral shape and are evenly distributed around the periphery of the tree. 3-6ml insecticide is filled in each hole, the insecticide is applied every 15-20 days, and the tree holes are sealed totally after the insecticide is applied for 3-5 times continuously. The hydrolytic enzyme in the method has decomposition function for resin secreted by the tree body, so as to reduce the influence for medicine permeability caused by the inset damages and a large number of resinosis easily after wound processing.
