Every year, the disease starts to occur on sunflower in the middle and late growth stages of sunflower.The pathogen usually invades the plant from natural cracks and wounds.When it is frequently rainy and very humid from mid-August to mid-September,the condition of the disease is serious, while the condition of the disease is mild when the weather is opposite.
