Pear tree rot disease prevention and control method

1. Strong tree disease prevention:
(1) Reasonable burden: According to the tree's reproductive status and fertilization level, determine the appropriate amount of results, do not overload the tree, and do not take excessive measures such as pulling branches and girdling for the sake of recent benefits. . To properly spend thinning and fruit thinning, the result should be correct.
(2) Increasing fertilizing water: For the northern pears, the most common phenomenon is the lack of fertilizer and water. In the fertilization, we must pay attention to increase organic fertilizer, pay attention to increase phosphate fertilizer, potassium fertilizer and trace element fertilizer; but at the same time but more partial nitrogen fertilizer.
(3) Protecting the leaves and promoting the roots: timely prevention and control of diseases and insect pests that cause early defoliation, such as scab, gray leaf spot, black spot, brown spot, red spider, pear net, aphid, and leaf roller moth. At the same time, we must also pay attention to prevention and control of various root diseases.
2. Avoid and protect wounds:
(1) Thorough prevention and control of branch pests: The branchworm pests such as gizilidae, periatus, and longhorned cattle are not only the manufacturers of wounds, but also the carriers for carrying and transmitting pathogens, and they completely prevent and treat these pests. important.
(2) Prevention of frost damage and sunburn: The temperature difference between day and night in the sunny side of pear branches is large, and they are prone to frost damage. If each sun side has no leaves covered, it is easy to die off due to the sun in summer. To prevent freezing injury more effective measures, first, the trunk painted white, reduce the temperature difference between day and night; second is the trunk of hay, cover frost. The commonly used whitening agent formula is 12 to 13 kg of quick lime. Add lime sulfur mixture solution (20 Baume degrees) 2 kg, add salt 2 kg, add water 36 kg; or lime 10 kg, add milk 3 to 4 kg, add water 40 to 50 kg. Whitening can also prevent the branches from drying on a daily basis.
(3) Protect the wound: The larger saw cut should be flattened and then coated with tung oil, varnish or thiophanate ointment, and S-921 antibacterial agent. Large lesions should be bridged and protected in time after they are cured.

3. Timely treatment of lesions:
(1) Scrape the bark: scrape off the bark and necrotic tissue before sprouting. After scraping the skin, combine the coated or sprayed medicine. Can be sprayed with 50% by weight of Fairfax WP 300 times, or 1 to 3 degrees lime sulfur.
(2) Treatment of lesions with pharmacological agents: After scraping off the diseased tissue, apply 1 part of 70% thiophanate-methyl powder and 2.5 parts of vegetable oil, or mix 50% carbendazim WP and 1.5 parts of vegetable oil to smear the diseased part. . It can also be applied to Baume 5 to 10 degrees lime sulfur, S-921 antibiotic 20 to 30 times, 40% femtamine 50 times or 30% rotten enemy 30 times, 843 remedy stock, and lyramycin broth 5 times liquid, etc., to prevent disease relapse. The exposed xylem can be coated with coal tar or rust-proof paint; the bridges on the larger trunks are promptly bridged to restore the tree potential as soon as possible. The scraped bark and diseased branches were burned together.

Nuts can generally be divided into two types: one is seeds, such as sunflower seeds, pumpkin seeds, peanuts, etc.; the other is tree nuts, such as pistachios, hazelnuts, cashews, walnuts, pine nuts, walnuts, chestnuts, almonds.
