A: Every year from April to June is the season for laying of a longhorned beetle. Therefore, the inside of a tree cavity is affected by the larvae's erosion and drilling pits, which will hinder the normal growth of fruit trees and weaken the tree vigor. When the victim suffers serious damage, it can cause the entire tree to quickly wither and die. Corroded trees are also prone to intrusion of other pests and germs, and they are easier to break when a gale strikes. For the control of natural calf, an effective method is usually selected: dipterex is diluted with water (the dilution concentration is 30 times), then the syringe is used to inject the syrup into the dented tree hole, and then the medicine sponge soaked in the medicine is used to plug the hole. . Mothballs can also be used to crush and put into tree holes, and plug the hole with a puddle of medicine.
