How to treat tomato wilt

1. Symptoms of the disease

Fusarium wilt often occurs during the flowering and fruiting period of tomatoes, especially during the peak fruit-bearing period, which can cause the plant to die. When the disease first occurs, the lower and middle leaves of the plant will wilt at noon, but will recover in the morning and evening. Afterwards, the leaves will gradually turn yellow from bottom to top, but will not fall off, and the plant will slowly wither and die. It may develop disease on one side of the plant while the other side remains healthy.

2. Causes

There are many reasons why tomatoes may develop wilt. For example, the soil is heavy and acidic, and contains certain pathogens. Or it may be due to pests such as nematodes in the soil, which spread the disease to the plants. It may also be because the nutrient soil or organic fertilizer is contaminated with bacteria and has not been fully decomposed. In addition, too much nitrogen fertilizer or continuous rainy weather followed by clear weather can easily cause it to become diseased.

3. Treatment Methods

For wilt disease, the first thing to do is to remove the leaves that are more seriously affected to prevent the disease from getting worse or spreading to other parts. The picked leaves should be burned to completely kill the pathogens. Then make a spray with Qingkulike, Wofengsu and garlic oil, and also water the roots. If the condition is more serious, methyl thiophanate may be needed for treatment.

4. How to prevent

To prevent tomato wilt, you must first choose varieties with strong disease resistance and pay attention to crop rotation. During this period, you must also remove weeds and deep plow the soil. If you use nutrient soil, you need to sterilize it and place it in a sunny place for about three weeks. When transplanting, pay attention to spraying disinfectants, do a good job of drainage during the rainy season, and use decomposed organic fertilizers for watering.
