What are the causes of fruit tree rot disease?
Rot disease is a disease that fruit growers often encounter. If it is not treated in time when it occurs, it can lead to the death of fruit trees, and there are many causes. How many do you know? Come and take a look at these causes with the editor below!
1. Soil that is not breathable
The soil needed by many fruit trees is loose and breathable. In addition to being beneficial to the growth of fruit trees, such soil is mostly meant to prevent these diseases. If the root system of a fruit tree remains in soil that is thick and highly viscous for a long time, then its root system's demand for air will not be satisfied. In this way, some pathogens will slowly erode the tree body and breed more harmful pathogens, leading to the appearance of rot disease. If the soil layer remains compacted for too long, it will lead to the death of the entire fruit tree.
2. Water rot
Water is very important to fruit trees, but too much water is also very harmful. Water rot is caused by too much water in the soil layer, or by water submerging the surface soil. In such cases, the root system of the fruit tree is eroded by water for a long time and will slowly breed some harmful substances, resulting in soaking and rotting. In severe cases, it will slowly decompose the surface layer of its bark, erode the entire plant, and cut off the gas circulation within its body. Therefore, drainage measures must be done well, and the degree of soil moisture should be noted during daily watering.
3. Fertilizer rot
Fertilizer rot is also a relatively common situation. There are two ways it occurs: one is caused by fertilizer being directly scattered on the root system, and the other is caused by too much fertilizer, with the latter being more harmful. The former very easily causes the contacted area to undergo a chemical reaction and rot, while the latter easily causes biological rot in the fruit tree, simply put, excessive nutrition. When either occurs, the condition of the leaves can generally be observed. If batches of leaves turn yellow and there is no influence from other pests or diseases, then it is best to check where the fertilizer was applied.
4. Excessive moisture
At present, fruit tree planting emphasizes planting in rows and columns, with space reserved in between and the ability to allow airflow through. In addition to making management convenient, there is another meaning: preventing excessive moisture. When moisture is excessive, the probability of fruit tree disease is at least 50% higher. Water vapor will continuously corrode the surface of the fruit tree and reduce its preventive ability. Excessive moisture has a great impact on fruit tree rot disease. In daily care, it is best to ensure that some scattered sunlight can also reach the bottom.
The above are the causes that often lead to fruit tree rot disease. These factors can often be controlled artificially, and growers just need to pay a bit more attention. For more related information, you can browse our website.
