Why do Chinese cabbages get viral disease? How is it treated?
Cabbage viral disease, also known as "guding disease" and "choufeng disease", together with downy mildew and soft rot is known as one of the three major diseases of Chinese cabbage. In ordinary epidemic years it can cause about 10% yield loss, in some severe outbreak years it can reduce yield by more than 30%, and in seriously affected areas it can even cause total crop failure, severely affecting the yield and quality of Chinese cabbage.
