What Causes Root Rot in Fruit Trees? A Detailed Guide to the Latest Prevention and Control Measures

Whether it is the roots, stems or leaves, each is an important part of a fruit tree and none can be missing. If something goes wrong in any part, it is a serious blow to the yield and quality of the fruit tree. Among these, the root is the most important part. Whether it is nutrient absorption or the survival of the fruit tree, the role of the root is indispensable. Therefore, when growing fruit trees, the thing most feared is root rot. Once root rot occurs, in mild cases the yield is reduced, and in severe cases the tree dies. So what causes root rot in fruit trees? How should it be prevented and controlled? Let us learn about it together.

1. Symptoms of root rot in fruit trees

If root rot occurs in a fruit tree, for beginners the only way to judge is to dig out the roots and see whether they are blackened or have a foul odor, while experienced farmers can judge by the external appearance of the fruit tree. First, you can judge by the leaves. If the fruit tree has root rot, nutrients cannot keep up, so the leaves will certainly turn yellow and withered or even fall off. As for the fruit, because the fruit lacks nutrients, it will be very small and taste rather astringent. You can also judge by the performance of the branches and trunk: the branches and trunk become very brittle and break extremely easily.

2. Causes of root rot

There are many causes of root rot in fruit trees. First, there is the cause of waterlogging. If the orchard remains waterlogged for a long time and drainage is not carried out in time, the root system will absorb a large amount of water, which reduces respiration and root activity, leading to root rot. If the weather is too dry or the temperature is too high, the roots close to the ground surface may also suffer root rot due to lack of water. If the temperature is too low in winter, the surface roots may also suffer root rot due to injury. When fertilizing, applying organic fertilizer that is not fully decomposed may cause root infection, or applying fertilizer at too high a concentration may burn the roots and lead to root rot. Pests and diseases are also one of the causes of root rot. In addition to aboveground pests and diseases, there are also underground pests and diseases. In dark and humid environments, pests are extremely likely to breed, biting the roots and causing injury and decay.

3. Prevention and control measures

To prevent and control root rot in fruit trees, you must first create a favorable environment for the fruit trees. The orchard should be reasonably planned with drainage ditches, so that in the rainy season rainwater can drain away in time. You can also earth up around the root system, so that rainwater does not easily flow in and leave the roots soaked in water. Fertilization should be reasonable. Organic fertilizer and farmyard manure must be fully decomposed before being applied. When topdressing, fertilizer should not be applied directly at the roots; instead, dig trenches or holes nearby and apply it there, so as not to injure the roots.
