The pathogens mainly overwinter in the seeds, and can also overwinter in the soil along with the diseased remains. Can survive for 2-3 years. After the plant becomes ill, it produces pus, which is spread by wind, rain and insects, and invades from the water holes, stomata and wounds of the plant leaves. The most suitable temperature for the onset of the disease is 30°C, and the disease is severe under high humidity and high temperature conditions. |
