How to prevent and control sorghum black rot

Symptoms can be diseased at seedling stage and adult stage. During the seedling stage, the disease appeared as a lack of water-like wilting. The cortex and vascular bundles of the diseased seedlings were brownish and watery, and the fine roots were softened and rotted. The diseased leaves of the infected plants droop slightly and the old leaves yellow, starting to dry from the tips of the leaves and the leaf margins. The infected roots and roots of the roots turn brown and rot.
