In Zhejiang Province, the disease began in late March and early April, and entered the peak period from May to June. The disease began in the northeast in June. Temperature 20 ~ 25 °C, relative humidity higher than 80% susceptible to disease. Rainy days, rainfall is large and popular.

Control methods (1) selection of disease resistant safflower varieties; (2) appropriate sowing. (3) Begin spraying 70% mancozeb WP 500 times or 50% benomyl WP 1500 times, 25% Carbonate wettable powder 500 times, 40% konkon suspension 700 times liquid agent.
