After the onset of the disease, there will be many light yellow and irregular disease spots on the diseased leaves. Then the disease spot will gradually expand and extend and merge with each other, resulting in the whole leaf withering and yellowing. When the humidity is high in the field, a mildew layer will be produced on the back of the disease spot, which gradually extends to the leaves. In severe cases, all the leaves are yellowish brown and all die, resulting in a more than half reduction in yield.

Rot disease

Rot is one of the most common diseases of chicory, which usually begins in the middle of its growth and, in severe cases, leads to the loss of chicory throughout the day. Like downy mildew, rot mainly starts from the leaves or stems at the base of the plant, which produces yellowish watery spots, and then gradually spreads upward and petioles. When the humidity is too high, the spot will gradually soften and rot, and then arachnoid bacteria appear at the base. When the humidity is low, the plant will wither and die, and sometimes accompanied by a foul smell.
