Identification and Control Methods of Southern Blight in Japanese Euonymus
Southern blight in Japanese euonymus is caused by a fungus and is characterized by being highly destructive and spreading rapidly. If not controlled properly, it can cause the death of all seedlings. Based on past work, we have summarized the characteristics and control methods of southern blight in Japanese euonymus. Symptoms: In the early stage of the disease, the stem or leaf base near the soil turns brown and rots. After a few days of sun exposure, white silky mycelium appears on the diseased parts and soil surface, spreading radially through the rhizosphere soil. Later, brown, rapeseed-shaped small sclerotia grow on the stem near the soil surface, often causing the death of the entire plant.
