Answer: When the watermelon stems and leaves are sprayed with herbicides in the nearby corn fields, the phytotoxicity caused by the drift of the wind drifts occurs every year. The light growth points are damaged and curled, and the heavy ones die. It is still difficult to avoid in the case of small-scale planting of farmers. Therefore, we must first do a good job of prevention. You can spray the watermelon on the watermelon field a few days before the start of spraying the herbicide, and spray it again after the corn field is sprayed. If there is no "killing spirit", foliar fertilizer such as sputum, tianfengsu, etc. can also be used to relieve or reduce the harm of herbicides. When there are conditions, you can make a paper cap on each melon (female flower), which can prevent the rain from washing off the pollen after artificial pollination, and can reduce the harm of the melon tire by the mist of the herbicide. In the last year, I planted the watermelon plot. In the next year, I can change the location of the melon ditch and the crawling place. It is best to use grafting to prevent soil-borne diseases such as blight. Before the melon seedlings are planted, spray the fungicide such as carbendazim on the melon to disinfect the soil. When the watermelon begins to sit on the melon or when there is blight, use the fungicide such as carbendazim to control the soil-borne diseases such as blight.
