Prevention and control of tree rot: causes of fruit tree rot and how to treat fruit tree rot

Rot is a disease often encountered by fruit growers. Failure to treat the disease in time will lead to the death of fruit trees, and there are many causes. How many do you know? Let's take a look at these reasons with the editor.

1. The soil is impervious.

The soil needed by many fruit trees is loose and breathable, which is not only beneficial to the growth of fruit trees, but also to prevent these diseases. If the roots of fruit trees are thick and viscous for a long time, their demand for air will not be met, so some germs will slowly erode the trees and breed more harmful germs. leading to the emergence of its rot. If the soil layer is hardened for too long, it will lead to the death of the whole fruit tree.

2. Water rot

Water is very important to fruit trees, but if there is too much water, the harm is also great. Water rot is caused by too much water in the soil layer, or by submerging the surface soil. In this case, the root system of the fruit tree will be eroded by water for a long time, and some harmful substances will be breed slowly, soaking and rotting, and in serious cases, it will slowly decompose the surface layer of its bark, erode the whole plant, and cut off the gas circulation in its body. Therefore, drainage measures must be done well, and attention should be paid to the degree of soil moisture when watering every day.

3. Fat rot

Fertilizer rot is also a more common situation, there are two kinds of disease, one is caused by spraying fertilizer directly on the roots, and the other is caused by too much fertilizer, the latter is more harmful. The former and the parts that are easy to come into contact with are prone to chemical reaction decay, while the latter are prone to biological decay of fruit trees, which is simply overnutrition. When both occur, you can generally observe the leaves. If a batch of leaves turn yellow and there is no impact of other diseases and insect pests, then it is best to check the place of fertilization.

4. Excessive moisture

Now fruit trees are planted according to the row, in the middle to reserve a good space, and can permeate the air flow. In addition to facilitate the management of accidents, there is another meaning is to prevent excessive moisture. In the case of excessive moisture, the incidence of fruit tree disease is at least more than 50% higher, and water vapor will constantly corrode the skin of fruit trees and reduce its prevention ability. Excessive moisture has a great impact on fruit tree rot, so it is best to make sure there is some scattered sunlight at the bottom every day.

These are the reasons that often lead to the occurrence of fruit tree rot, these factors can often be artificially controlled, farmers pay more attention to it, more relevant information can be read on our website.

Alkali water impregnation method

The alkaline solution was prepared by mixing edible alkaline noodles with water in the ratio of 1 ∶ 5. Scrape off the scar and fully smear the alkali water on the scar with a small brush, surpassing the scar by more than 5 cm, so that the alkali solution can fully enter the bark. Then wrap it tightly with plastic film, do it again 10 days later, and remove the plastic film half a year later. The cure rate of this method is over 85%.

Brine impregnation method

Mix salt with 2.5% of the salt and boil it in a pot. Cool and set aside. Then shave off the scar. In March to April or August to September, scrape off all the diseased scar and necrotic bark from the branches of fruit trees with a sharp knife, so that there is no diseased tissue around the scraped scars. Then cut the bark around the scar into a slope of 45 to 60 degrees to facilitate scar healing. Smear the salt water on the scraped scar with a brush, its smear range should be more than 2 cm, scrape one place, besmear one place, and apply again in half a month.

Garlic solution sterilization

Mash the garlic into mashed garlic and add 10% salt water according to the proportion of 1 ∶ 1 to make garlic liquid. First scrape off the scar, apply the liquid on the scar with a small brush or brush, surround it by 3 to 5 centimeters, and apply it again 10 days later. The cure rate of this method is above 90%.
