A: The main pests of apple trees in autumn include peach borer, boat-shaped caterpillar, gold-lined moth, and big leafhopper, etc. Diseases include rosy-ring disease, anthrax, and rot disease. The rot disease is now at the peak of the second (autumn) incidence in the whole year, and must be promptly scraped off and coated with drugs for prevention and treatment. Other pests and diseases should be combined with the local pest situation and disease conditions to do a good job of comprehensive prevention and control to improve the good fruit rate. This has a significant effect on preventing young trees from drawing and improving the winter cold resistance of trees.
