Eggplant blight disease mainly affects fruits, leaves, stems, flowers and other parts. Near-ground fruit first onset, the affected fruit is initially water-stained round spots, slightly sunken, the flesh becomes dark brown and rot, easy to fall off; when the humidity is high, the surface of the diseased part grows dense white cotton-like hyphae, and expands rapidly. The disease fruit is quickly corrupted.
The stem was stained at the beginning of the disease, and then darkened green or purple-brown. The diseased part collapsed, and the upper branches and leaves sagged; when the humidity was high, the white mold was sparse. The damaged leaves are irregular or nearly round water-stained pale brown to brown lesions, with obvious wheel pattern. When wet, the lesions are sparsely white, and the seedlings are easily damaged.
