What is Chinese elm tree blight?

Chinese elm tree blight, also known as Dutch elm disease, is a fungal infection caused by the pathogens OphiOStoma ulmi and OphiOStoma novo-ulmi. It primarily affects elm trees, including the Chinese elm, leading to symptoms such as wilting, yellowing leaves, and ultimately tree death. The disease is spread by bark beetles that carry the fungus, making it difficult to control once established in an area. Effective management includes removing infected trees and preventing beetle infestations.
