Detailed Explanation of the Causes and Prevention Measures of Fruit Tree Root Rot

For fruit trees, whether it is the roots, stems or leaves, they are all important parts of the tree, and none can be missing. If something goes wrong somewhere, it is a serious blow to the yield and quality of the fruit tree. Among them, the root is the most important part. Whether it is nutrient absorption or the survival of the fruit tree, it cannot do without the role of the root. Therefore, when planting 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 fruit tree root rot? How should it be prevented and controlled? Let us understand together.

1. Symptoms of Fruit Tree Root Rot

If root rot occurs in a fruit tree, for beginners the only way is to dig out the roots and see whether they are blackened or have a foul smell to judge, while for experienced farmers, it can be judged through the external appearance of the fruit tree. First, it can be judged by the leaves. If the fruit tree has root rot, nutrients cannot keep up, so the leaves will surely turn yellow and even fall off. As for the fruit, because the fruit has no nutrients, it will be very small in size and taste rather astringent. It can also be judged by the appearance of the branches. The branches become very fragile 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 is in a waterlogged state for a long time and drainage is not carried out in time, then the root system will absorb a large amount of water, which leads to weakened respiration and reduced root activity, causing root rot. If the weather is too dry or the temperature is too high, the roots close to the ground may also cause root rot due to lack of water. If the winter temperature is too low, then the surface roots may also cause root rot due to damage. When fertilizing, applying organic fertilizer that is not fully decomposed may cause root infection, or if the fertilizer concentration is too high, it burns the roots and causes 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 a dark and humid environment, pests are extremely likely to breed, biting the roots and causing injury and rot.

3. Prevention and Control Measures

To prevent and control fruit tree root rot, first of all, a favorable environment must be created for the fruit trees. The orchard should have reasonable drainage channels arranged, so that in the rainy season the rainwater can be drained out in time. Soil can also be banked up around the root system, so that rainwater is not likely to flow in and leave the roots soaking 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, trenches or holes should be dug nearby for application, so as to avoid damaging the roots.
