How to prevent and cure the epidemic disease by planting beans? Please introduce the methods of prevention and control of bean blight with reference to the following methods: 1. The symptoms are mainly harmful to stems, leaves and pods, mostly in or near stem nodes, especially near the ground. The disease part was water-stained at the beginning, then the wet rot constricted around the stem, and the leaf vines above the disease part withered and died.
