Glue-feeding disease is a common disease affecting stone fruit trees such as peach, peach tree and peach tree. It can cause premature aging of tree vigor and yellow leaves. The disease can occur in the trunk and main branches of Bitao, Peach, and Lishu. I. Symptoms Physiological problems of peach trees mainly occur on trunks and main branches. The incidence of trunk disease is most prominent. The disease is swollen at the beginning of the disease and the gum is continuously flowed out. 3-4 plastic beads are linked together to form a diameter of 3 -10 mm irregular round plastic lesions, the gum is transparent or brown at the beginning, over time, soft gum becomes a hard plastic block. The disease will cause the bark and xylem to rot. The tree vigor will become weaker and the leaves will turn yellow and become smaller. When the disease is serious, the whole tree trunk will die. Second, the pathogen and the incidence of the law flow gum disease is caused by the grape Gracilaria, Pityrosporum infection. In addition, trunk pests, frost damage, frost damage, soiling, soil viscosity, and various bark damage or ring-cutting bark can also cause fluids to flow. The pathogenic bacteria that flowed gums were overwintering in diseased tissues of trunks and branches, and a large number of conidia were produced before and after sprouting of peaches in the second year. They spread by wind and rain, and invaded from wounds or lenticels, and could be reinfested later. High humidity is an important condition for the occurrence of diseases. In spring, low temperature and more rainy and cloudy rain can cause trunk disease. In the high-temperature and humid conditions in Hengshui, it is a period of high incidence from June to August. The pathogenic Myzustomium spp. spreads through branches and bark. The initial infection, the conidial germination temperature of 8 °C -40 °C, the optimum temperature of 24 °C -35 °C, relative humidity of 85% -90%. The pathogenic bacteria in the trunk and shoots were overwintering and were sprayed from late March to mid-April the following year. The spores spread with air currents and falling water droplets, and then invaded the bark from twigs or wounds. In the case of extensive management, poor drainage, soil viscosity, and debilitating trees, diseases are prone to occur. Third, control methods 1. Strengthen management. Peach trees are resistant to drought and are suitable for planting in sandy loose soil. Increase organic fertilizer and improve soil, clay should be mixed with coarse sand, row of water, enhance tree vigor, improve disease resistance and reduce unnecessary mechanical damage. 2. Pruning the garden in winter. During the winter, the diseased branches and branches must be cut off and burned in a concentrated manner. Spray 29% lime sulfur for 150 times to disinfect the trees to reduce the bacteria source. The trunks should be painted white to prevent freezing damage and sunburn. The peach aphid and peach aphid should be strengthened. Foraging pest control, reduce pest damage to the bark. 3. Scraping applicator. Scratch before and after germination, then apply fungicide, apply 100 times liquid antibacterial agent 402 before germination or in the spring to apply lesions, use 1:1:100 Bordeaux mixture or 50% with special wettable powder 800 times, 50 times Carbendazim 500 times spraying or smear diseased plants to kill germs and reduce the source of infection. 4. Drug control. Before the sprouting in early spring, 5 waves of Baume degree lime sulfur or 50% of eutectic wettable powder are sprayed 800 times to kill the pathogenic bacteria after the winter, spraying once every 10 days, and even spraying 3 times. Spraying 72% of agricultural streptomycin sulfate 4000-5000 times in the early stages from the end of March to early April, spraying once every 7 days, spraying 2-3 times, and also using 50% of the special WP. Liquid or 50% carbendazim 800-1000 times, 50% thiophanate-methyl 1000-1500 times, spray once every 10 days, even spray 3-4 times. When the disease is serious, 25% sulfac emulsion 500-800 times, 50% Shi Baogong WP 1000-1500 times, 50% TB wettable powder 800 times, 70% Mancozeb may be wetted. Powder 500 times liquid, 80% anthrax Fumei wet powder 800 times spray, spray every 7-10 days, even spray 3-4 times, the above pesticides are best used interchangeably. From late March to early April, when peach pods and peach pods were hatched in large quantities, spray 50% phoxim emulsion 2000 times, 80% DDVP 1000 times, and spray 1-2 times; in peach aphid and peach aphid After the hatching, spraying 50% anti-influx 2000 times liquid, 10% imidacloprid wettable powder 2000-4000 times liquid or 20% cypermethrin 3000 times liquid, the control effect is better.
