Experts believe that there are two causes of the pathogenesis of Peach Glue: One caused by physiological factors, such as mechanical injury, disease and insect damage, frost damage, frost damage, etc., resulting in fluid or excessive management, excessive trimming, and excessive results. Fertilizers caused by physiological disorders of tree body caused by inappropriate fertilization, soil viscous weight, etc., occur mainly on the stem and branch, and in severe cases, branchlets can also be affected. The other is caused by germs infestation. The pathogens are invaded by wounds and can also invade from lenticels and lateral buds. They mainly damage branches and invade fruits. "The cause of Peach Glue disease is complicated. It is difficult to distinguish whether it is caused by physiological factors or caused by pathogenic infections, which makes it difficult to control." Ma Ruijuan said that the south is hot and rainy, the groundwater level is high, and the soil is sticky. It is prone to peach gum disease, especially after summer rain. Heavy-duty, peach trees with paclobutrazol increase weight. Glue deficiency can severely shorten the lifespan of peach trees. Generally, the useful life of peach trees can reach 15 years, while the trees with heavy glue can only be about 10 years old. Pesticide prevention and control in production requires comprehensive measures. (1) Strengthen cultivation management. Apply more organic fertilizer, appropriate application of phosphorus and potassium fertilizer, nitrogen fertilizer control in the later period. Reasonably load and trim, maintain stable tree potential. Do a good job of drainage during the rainy season. At the same time, prevent and treat other diseases and insect pests, reduce the wounds of insects and insects, and do not prune summer rainy days to reduce mechanical wounds. (2) After clearing the garden in winter, scraping rubber and spraying lime sulfur, the tree trunk and large branches were painted white. (3) Prior to the germination of the peaches, Bami 5 degree lime sulfur was sprayed. (4) When peach trees begin to flow, the quicklime powder is applied to the plastic flow. At this time, there are few trees, and the flow range is small, which is easy to control and reduce the nutrient consumption of the tree; (5) In the growing season, medications should be controlled in a timely manner. From late March to mid-April, combined with prevention and control of other diseases, spraying thiophanate-methyl, copper ammonia or carbazole carbazole and other drugs for prevention and treatment. Early May to early June, early August to early September are the two peak periods of invasive fluidosis. On the eve of each peak, 50% of the bacteria are used every 7 to 10 days. Zinc thiram WP 800 times, 70% mancozeb WP 500 times or anthrax FX 80% WP WP 800 times spray control, alternating medication, continuous control 2 or 3 times.

Peach plastic disease focuses on integrated prevention and control
Glue-feeding disease is a common disease on peach trees, especially in Taoyuan, where management is extensive and tree vigor is weak. The rate of diseased plants can reach 90% or more. The disease seriously weakens the tree vigor and shortens the service life of trees. Dead tree dead tree. According to researcher Ma Ruijuan, an expert on peach research at the Institute of Horticulture, Jiangsu Academy of Agricultural Sciences, Peachleaf gum disease is caused by a variety of factors. At present, there is no particularly effective medicine to prevent and treat this disease. Controlling the disease focuses on comprehensive prevention and control.
