What is peach leaf shrinking disease?

What is peach leaf shrinking disease? Please introduce the leaf shrinking disease of peach trees, which mainly harms leaves, as well as young branches and young fruits. The pathogen passes the summer with ascospores or spores in bark or bud scales, and the spores will continue to sprout when the conditions are right. Spores spend the winter in scales and bark. The disease usually occurs from April to May, and the harm usually occurs only once in that year. The fruit turns red when sick, the diseased part is swollen, the hairs fall off, and the surface is smooth. Prevention and control methods: (1) agricultural control. When building a new peach orchard, the varieties with high yield, high quality and disease resistance were selected. For peach orchards entering the fruiting period, it is necessary to do a good job in soil, fertilizer and water management, carefully shaping and pruning, and improving ventilation and light transmission conditions. In the peach orchard with serious disease, the peach orchard should be fertilized and irrigated in time, and the melon and fruit Zhuangtiling should be sprayed to thicken the nutrient pipe, enhance the tree potential and improve the disease resistance. From April to May, combined with pruning during the growing period and control of longicorn beetle larvae, it was found that the leaves of leaf shrinking disease were removed immediately and burned centrally. Spray tree protection general 1000 times solution for sterilization and disinfection to inhibit the spread and replication of bacteria. (2) Pesticide control. Spray 1000 times liquid of tree protection general in dormant season to eradicate overwintering pathogens. When peach buds begin to swell in spring, it is a critical period for the prevention and control of peach leaf shrinkage disease. Spray tree protection general 1000 times liquid, or 70% methyl thiophanate wettable powder 1000 times solution, or 50% carbendazim gum suspension 1000 times solution. From March to June in the growing season of peach trees, that is, after leaf expansion to the arrival of high temperature and drought weather, methyl topiramate or carbendazim can be added to the new high fat membrane to preserve soil moisture and enhance the efficacy. The diameter of the disease spot of early leaf shrinking disease was about 0.2 cm. When the fungicide was sprayed, the disease spot was obviously inhibited.
