The ten methods of physical prevention and control of diseases and pests of fruit trees are based on the hazards and habits of pests and diseases. They can directly use artificial or simple tools and adopt ten methods for physical and mechanical control, which can effectively prevent the environmental pollution caused by chemical control and reduce the drug residues in fruits. , The operation is simple and practical, specifically to grasp the following ten aspects: 1, cut combination of winter and summer cut, the diseased branches, eggs, sticks, nuts, fruit and other cut off. 2. In the growing season, the use of the pseudo-death feature of pests, such as beetles, is shocked by the tree to make it fall, and then it is collected for killing; in the event of haze in the winter, it can hit the branches and cause the scale insects to shake off. 3, clear to keep the orchard clean. In winter, combined with winter shears, thoroughly cleans the orchard to remove diseased branches, dried dead fruits, fallen leaves, etc., eliminating the source of sterile insects. In summer, the small damage to the jujube garden can be manually picked up in August to reduce the density of second-generation peaches. . 4. Scraping removes sticks, dry skin, and rot lesions. Some pests, such as red spiders, have wintering habits in the bark seam and can be scraped off. 5. The brush has serious branches on the scale insects. You can brush off the overwintering nymphs and oocysts with a bristle brush to reduce the number of insects. This method can also be used during the growing season. 6, induced that the use of pests on a strong tendency of a certain substance or condition to seduce, such as the use of light traps to kill moths, beetles adults, bait wood to kill beetles, weevils, with insect sex traps to kill pests, mainly peach small Fresh-spotted moths, gold-grained moths, pear borer bugs, apple leaf roller moths, peach aphids, etc. 7, resistance to early defoliation, spider mites, peach and other small underground wintering habits, can be implemented in early April mulching, do not make pathogens, pests on the tree, and eliminate excavated larvae and adult emergence. Jujube trees and high-rising areas of the footsteps of the jujube trees piled up in early March to pile up mounds, dig isolation troughs or bundle unwound plastic on the tree trunks to prevent pests from growing on trees, and to collect and kill them every morning. 8, capture that artificial capture to kill pests, such as the summer catch Tianlong adults, pupa larvae and so on. 9, turn over the combined fertilization, deep-turning the tree plate, remove insects, while pests crouched in the ground due to being cleared to the surface and can not die over winter. 10, powdery mildew, rust easily popular in the summer when the high temperature and dry, pimple, pimple, pimple, etc. also like the dry and windless environment, such as the occurrence of the initial stage of the pest or the occurrence of the lowest when using high-pressure spray gun, can effectively alleviate pests and diseases .
