Pear yellow meal is mainly caused by adult nymphs and nymphs concentrated in the pear stalks, and can also be harmful in other parts; it is quite harmful to bagged green pears. In combination with the prevention and control of other pests and diseases, all kinds of old warts on the trees are scraped off in winter; combined with winter shears, the various residues on the trees are eliminated and burned intensively to eliminate the overwintering eggs. Actively protect and utilize natural enemies. Common predatory insects in the northern pear orchard include ladybugs, grasshoppers, etc., as long as certain protective measures are taken, the population of the yellowfly is better controlled. In the early spring, the application should focus on the trunk and the base of the main branch; during the growing season, it is necessary to pay attention to make the fruit evenly spread, especially the crotch (more attention should be paid to the surviving varieties of the bracts).
