Symptoms: Purple onion spot disease is an important disease of green onions, but also harm onions, garlic and so on. The main damage to the leaves and pedicels, but also damage leaf sheath, lesions at the beginning of water spots like small white spots, a slight depression, after the expansion into an oval or spindle-shaped, brown or dark purple, often around yellow halo. Several lesions healed to grow large strips. When wet, the diseased area produces dark brown or dark gray moldy layers in a concentric ring pattern. When the disease is heavy, leaves, stems die or fold. The high incidence of pedicels in seed plants often causes the seeds to shrink and cannot mature sufficiently, affecting seed yield and quality.

Implement two-to three-year rotations with non-onion crops. After the harvest, clean the pastoral area and bury or burn the sick body. (2) Seed treatment.
