1. Common diseases

downy mildew

Downy mildew mainly occurs in spring and autumn every year. Downy mildew mainly damages chicory leaves. At the initial stage of disease, the leaves at the base of the plant are damaged first, and then gradually spread upward. After the disease will appear on the diseased leaves of many pale yellow irregular spots. Then the disease spots will gradually expand and extend, merging with each other, causing the whole leaf to turn yellow. When the humidity in the field is relatively high, mold layer will be produced on the back of the disease spot and gradually extend to the leaves. In severe cases, all leaves are brown and all die, resulting in more than half of the yield reduction.

Rot disease is the most common disease of chicory, usually beginning in the middle of chicory growth and can lead to an all-day failure of chicory when severe. As with downy mildew, putrefaction disease mainly starts from the leaves or stems at the base of the plant, and the diseased parts produce pale yellow water-stained spots, and then gradually spread to the upper and petioles. When the humidity is too high, the diseased spot will gradually soften and rot, and then spider silk bacteria will appear at the base. When humidity is low, plants wither and die, sometimes accompanied by a foul smell.

2. Prevention and control methods

Rot disease prevention is the main, in the prevention and control of rot disease, we must first select seeds, try to choose no pests or high disease resistance seeds. Then use carbendazim to disinfect seeds before sowing, control sowing time and sow in time, strengthen management and fertilize reasonably. In summer, it is also necessary to do a good job of shading, pay attention to drainage in rainy season, remove the diseased plants in time after finding them, and then spray them with thiophanate-methyl and other powders, mainly at the base of the plants.
