First, the onset of symptoms: more in the flowering results period. At the beginning of the disease, several leaves of the lower part of the plant wilted and drooped, and the whole plant appeared to be wilting from bottom to top. The mild diseased plants wilted at noon on sunny days, and returned to normal in the morning and evening and cloudy days. After several days, the diseased plants turned yellow and died, and the plants died in severe cases. The internal tissues of the roots and necks of the plants were browned, and the cortex was easy to fall off. For example, a small section of diseased stems was cut and placed in a test tube containing fresh water, and no white pus was discharged (this can be distinguished from bacterial wilt).
