How to prevent the harm of Corn herbicides in Watermelon

Q: watermelons are harmed by corn herbicides after wheat harvest every year. Is there a good way to prevent and eliminate them? In addition, how to avoid continuous cropping diseases in watermelon field? Answer: watermelon stems and leaves are affected by the fog droplets drifting along with the wind when spraying herbicides in nearby corn fields, resulting in drug damage every year. The light ones are damaged and curled, while the heavy ones are withered and dead. In the current situation of farmers planting in a small area, it is still difficult to avoid. So first of all, to do a good job of prevention, you can start spraying herbicides in the nearby corn field a few days before spraying the watermelon field, and spray again after spraying in the corn field. If there is no "Jieshan Ling", you can also spray brassine, Tianfengsu and other foliar fertilizer to relieve or reduce the harm of herbicides. When possible, a paper cap can be made for each melon embryo (female flower), which can not only prevent Rain Water from washing away the pollen after artificial pollination, but also reduce the harm caused by herbicide droplets. In the land where watermelons were planted last year, the places where melon ditches and seedlings can be climbed can be changed next year, and it is best to use grafting to prevent soil-borne diseases such as Fusarium wilt. Spray carbendazim and other fungicides on the melon beds before planting to disinfect the soil. When watermelons begin to sit or when Fusarium wilt occurs, fungicides such as carbendazim are used to control soil-borne diseases such as Fusarium wilt.
