Symptoms of downy mildew in Chinese cabbage: There are episodes from the seedling stage to the flowering stage and the crusting stage, but the most serious is the adult plant. 1. Seedlings suffer from damage. There is a white layer of frosty mildew on the back of the leaves, and there are no obvious symptoms on the positive side. Serious disease seedlings turn yellow and cause death. 2. In the adult plant stage, the outer layer of leaves usually begins to develop, and gradually spreads to the inner layer; from sporadic onset to the general incidence of all fields. Leaf disease on the front of the leaf shows the appearance of white frost on the back of the macula, which is the sporangia of the pathogen. When the disease is severe, the mold layer covers the entire leaf. In the end, the diseased part is yellow-brown to dark brown and dry and dead. 3. In stems, pedicels and seed pods, the medullary cells and cortical cells of the diseased part grow too much due to the stimuli of the bacteria, and they become swollen or deformed, commonly known as “head diseaseâ€. In wet conditions, the diseased part also produces white frosty mildew. The pods are curved and the grain is not full.
