Is root rot fungal or bacterial? What is the best treatment for root rot?

Root rot affects both vegetables and fruit trees, mainly harming the root system and the base of the stem, hindering the transport of nutrients, causing the plant to rot or die, and affecting yield. In prevention and control, we must take agricultural measures and pesticides to solve the problem fundamentally.

Is root rot fungal or bacterial?

Root rot is a fungal disease. Various pathogenic fungi such as Pythium, Phytophthora, and Fusarium may be the primary source of infection. After infecting crops, they will suffer from root rot. The roots of crops infected with root rot will rot, and the ability to absorb water and nutrients will gradually weaken. The final result is that the plants infected with root rot by pathogenic fungi will die. The main manifestation is yellowing and death of the leaves of the whole plant.

What is the best treatment for root rot?

1. Wheat root rot

The main thing is to use new disease-resistant varieties as much as possible, and use less or no self-retained seeds. Soak and mix the seeds with pesticides before sowing. The planting density should not be too crowded, the field should not be wet for a long time, and the seedlings should be properly squatted. Use mancozeb or sclerotinia to prevent and control in time in the early stage of the disease.

2. Root rot of tomatoes and green onions

Plant on high ridges, drain water in time after rain, remove the remains of diseased plants in time, and sprinkle quicklime around the holes of diseased plants for disinfection and sterilization. In the early stage of the disease, copper sulfate solution, methyl butortol wettable powder, and oxazolidinone wettable powder can be diluted with water for root irrigation for prevention and control.

3. Fruit tree root disease

Fruit trees have many and thick roots. In addition to normal agricultural prevention and control, after the disease is discovered, the seriously diseased roots can be removed and rooting powder can be applied to promote the growth of new roots. Copper sulfate or metalaxyl can also be used for root irrigation. After that, organic fertilizer and biological fertilizer can be added to improve soil quality, promote the strength of fruit trees, and increase disease resistance.

How to prevent root rot of fruit trees

Take kiwi fruit as an example. Kiwi fruit is a plant that likes water, but it also requires good drainage. Therefore, it is difficult to control the amount of water during the cultivation process. It is recommended to use pipes for watering when planting kiwi fruit, and have drainage ditches, and remove weeds in the soil in spring, summer and autumn.

The main symptoms of root rot in fruit trees include leaf wilting, flower bud falling, and fruit falling. If root rot is found, it is recommended to use carbendazim, metalaxyl, copper preparations for root irrigation, etc. according to the specified proportions for prevention.

Prevention of root rot when caring for flower pots

Root rot is most likely to occur when caring for potted plants. During the maintenance process, watering should be carried out according to the moisture content of the soil. As long as the soil is not allowed to become moist, the environment is kept ventilated, and appropriate use of carbendazim for spraying prevention can achieve good results.

Flower pots that are commonly maintained, such as orchids, roses, green ivy, lucky trees, lucky bamboo, etc., can be prevented from root rot by sun exposure, which can achieve very good results.
