O. novo-ulmi infestation can spread rapidly, causing severe damage and death to susceptible elm trees. Effective management strategies, such as tree removal, pruning, and applications, may be used to control the spread of the disease in affected areas. [4] Early detection and prevention are key in managing Dutch elm disease caused by O. novo-ulmi.
