Prevention and control methods of Fusarium wilt in continuous cropping of watermelon

Repeated watermelon wilt is a common disease when people grow watermelons. It has a particularly long incubation period and serious damage. It often occurs in plots where watermelons are repeatedly planted. So how should this repeated watermelon wilt be prevented? I will write down the methods to prevent this disease in a while, and friends who need it can focus on it.

Prevention and control methods of Fusarium wilt in continuous cropping of watermelon

1. Crop rotation and watermelon planting

When planting watermelons, in order to prevent the occurrence of this kind of continuous watermelon wilt disease, the best way is to implement crop rotation. That is, in those plots where watermelon wilt disease has occurred, watermelons cannot be planted in the second year. They can only be planted again after a gap of at least three years, and the diseased plants must be removed in time after they are found.

2. Choose disease-resistant varieties

If you want to prevent the occurrence of severe watermelon wilt disease, you can also spend more time on selecting watermelon varieties. It is best to choose those watermelon varieties with strong disease resistance. You can also use gourds as rootstocks to graft watermelon seedlings. This can also effectively prevent the occurrence of severe watermelon wilt disease in consecutive crops.

3. Drugs to prevent Fusarium wilt in replanted watermelons

Drugs can also prevent Fusarium wilt in repeated watermelons. During the watermelon seedling period, you can spray Qingkuli or irrigate it into the soil with water. When the watermelons are transplanted and the seedlings are allowed to grow, you should irrigate them again with Qingkuli. This can effectively prevent the occurrence of Fusarium wilt in repeated watermelons. In addition, when Fusarium wilt occurs in repeated watermelons during their growth period, you can also irrigate them with Qingkuli and garlic oil, and remove the diseased plants, which can effectively prevent other healthy plants from being infected.
