Hello dear! Peach tree disease prevention and control methods: Strengthen the comprehensive hunger and frank management of orchards

Do not establish peach orchards in high or low-lying areas with high water levels; Less delay in dismantling and applying nitrogen fertilizer to prevent growth. Reasonable pruning to improve ventilation and light transmission conditions, timely and moderate summer pruning, cutting off diseased shoots, and concentrated burning. In winter, the rotten tung conscientiously does a good job of clearing the garden.

Pesticide control: spray 4-5 degrees of stone sulfur mixture or 1:1:1 before germination

100 times Bordeaux liquid, spray once after flowering Cobo 800 times liquid. From May to August, spray agricultural streptomycin (10,000-20,000 times) or zinc ash solution (1 part of zinc sulfate, 4 parts of lime, 240 parts of water) or 600 times of 65% zeb zeb wettable powder.

Hello, peach rot on a peach tree is generally a canker of peaches. You can determine based on the peach tree canker symptoms I provided, and if the symptoms are the same as described, it is peach tree canker disease.

Symptoms of peach tree canker disease

After the peach fruit is infected by the fungus, it first forms a small round lesion on the fruit surface, which is slightly concave, light brown on the periphery, and grayish-white. Later, the lesion expands rapidly, and the depression deepens. Under humid conditions, a grayish-white mold layer is formed on the lesions, which are the conidia and conidia of the pathogen.

In the later stage, the lesions are dehydrated, and the flesh under it is soft and white, like rotten wood. The new shoots are damaged, forming dark brown spot ulcers. The leaves are damaged, the lesions are nearly round, grayish-brown.

Prevention and control measures for canker disease in peach trees

1) Strong trees to prevent diseases

Reasonable loading: Determine the appropriate amount of fruit according to the fertility status of the tree and the level of fertilization. Don't let the tree body be overburdened, and properly thin the flowers and fruits, so that the fruit grows and the tree is not wrong.

Increase fertilizer and water: For the northern peach area, the more common phenomenon is the lack of fertilizer and water. In fertilization, attention should be paid to increasing organic fertilizer, phosphorus fertilizer, potassium fertilizer and trace element fertilizer; At the same time, do not apply too much nitrogen fertilizer.

Leaf protection and root promotion: timely control of pests and diseases that cause early defoliation. Such as perforation diseases, leaf shrinkage diseases, rusts, as well as red spiders, aphids, leaf roller moths, etc. In addition, attention should be paid to the prevention and control of various root diseases.

2) Avoid and protect wounds

Avoid and reduce wounds on branches, and properly protect existing wounds and promote healing. Thorough control of branch pests, such as gidding, feather moth, longhorn beetle, etc.

Prevent frost damage and sun burning: The temperature difference between day and night on the sunny side of the peach tree branch is large, and it is easy to suffer from frost damage. The most effective measures to prevent frost damage are: first, the trunk is painted white to reduce the temperature difference between day and night; The second is to bundle the grass with the trunk and cover it for frost protection.

The formula of commonly used whitening agent is 12-13 kg of quicklime; Add 2 kg of stone sulfur mixture stock solution (about 20 Baumé), add 2 kg of salt, and add 36 kg of water; Or 10 kg of quicklime, add 3-4 kg of soy milk, add 10 to 50 kg of water. Whitening can also prevent the branches from burning in the sun.

Wound protection: Larger saw edges should be flattened and then protected by tung oil, varnish or Tobuzin ointment, S-92L antibacterial agent, etc. After the larger lesion**, it is necessary to carry out bridging and protection in time.

3) Timely ** lesions

Scrape the bark: scrape off the upturned bark and necrotic tissue before the peach tree germinates, and then spray 300 times of 50% Fumei arsenic wettable powder, or 1-3 Baumé stone sulfur mixture.

Agent** lesions: After scraping off the diseased tissues, mix 1 part of 70% methyl tobuzin wettable powder plus 2 5 parts of vegetable oil, or 1 part of 50% carbendazim wettable powder plus 1 5 parts of vegetable oil to evenly apply the diseased part, which has a good effect on ** lesions. You can also apply S-92L antimicrobial 20 30 times solution, 40% Fumei arsenic 50 times solution or 30% decay enemy 30 times solution, 843** stock solution, etc., to prevent scarring**.

Liangguoan: For peach trees, use Liangguoan 200-300 times liquid and silicone to spray evenly. Wofengsu:

Spray 150-300 times of Liangguoan, 600 times of Wofengsu, 1000-1500 times of garlic oil and silicone. Methyl tobuzin: Spray peach trees with 800-1000 times of 70% methyl tobuzine wettable powder.

1. Liang Guoan

If the peach encounters rot during the ripening period, it may be due to infection with soft rot, at this time, it is necessary to use 200-300 times of Liangguoan liquid and silicone for the peach tree to spray evenly, spray once every 10-15 days, a total of 2-4 times, can effectively alleviate the disease.

2. Wofengsu

During the ripening period of peach trees, after suffering from black spot disease, fruit rot will also occur, at this time, it is necessary to immediately spray 150-300 times of Liangguoan, 600 times of wofengsu, 1000-1500 times of garlic oil and silicone**.

3. Methyl tobuzin

After the peach tree is mature, it is necessary to maintain the ventilation of the environment, prune the diseased branches, dense branches and long branches in time, otherwise it will be infected with anthracnose and cause fruit rot, at this time, it is necessary to use 70% methyl tobuzin wettable powder 800-1000 times liquid to spray the peach tree, spray once every 10-15 days, a total of 3-4 times.

4. Precautions

When the peach tree is about to ripen, it should be bagged in time to avoid encountering continuous rainy season, resulting in cracks on the surface of the peach, causing the pulp to be exposed to the air and rotting, in addition, it is necessary to pay attention to the invasion of the limb moth pest, and spray it with 2000 times pyrethrin pesticides after discovery.

1. Fruit cracking is a physiological disease, which generally occurs in the secondary expansion period of fruit buds. At this time, the fruit enters the rapid expansion period, and the expansion of the flesh is often faster than the growth of the fruit, resulting in the cracking of the peel. Especially in the case of long-term drought and heavy rain, the fruit tree absorbs a lot of water, and the fruit expands rapidly, changing the skin of the fruit wax and expanding it, forming a cracked fruit.

Therefore, the water management of peach trees must pay attention not to make the soil too dry, and maintain suitable soil moisture during the fruit expansion period, so that the fruit expansion can be carried out smoothly. In the case of a prolonged drought, do not pour heavy water. After the rainstorm, it is necessary to drain the water in time and hoe to dry the moisture to reduce the excessive amount of water.

2. Peach fruit becomes soft and rotten along the abdominal suture line in the later stage, which is also a physiological disease. From the point of view of lack of nutrients, the main reason is calcium deficiency, peach trees are particularly sensitive to calcium, calcium deficiency not only appears at the abdominal line to become soft and rotten, as far as the whole peach is concerned, the hardness is also reduced, the taste becomes bad, and the storage capacity decreases. There are two ways of calcium absorption, one is root absorption and the other is foliar absorption.

In recent years, many fruit farmers have used a lot of unrotted organic fertilizers, especially chicken manure. Organic fertilizer is not fermented, after being applied to the soil, the mu wax produces a lot of heat in the fermentation process, and burns the tender absorption roots, which greatly affects the absorption capacity of the roots. The effect of foliar calcium supplementation is generally not obvious.

This has a lot to do with the calcium fertilizer varieties used in the foliar surface, as calcium is very mobile in the crop. It is suggested that foliar calcium supplementation is best to choose mannitol chelated calcium, Hehuang chelated calcium or fruit and vegetable calcium, etc., these calcium fertilizers can be conducted up and down left and right in the tree, so that the calcium on the foliar surface can be transmitted to the fruit, which increases the use effect of calcium.
