Dutch elm disease

6. Dutch elm disease

This fungus disease affects the vascular system of the elm, causing a rapid wilting and failure to all American and European species of elm. Millions of elms throughout North America and Europe have died due to this disease. Today, many new treatments are available to combat DED. Treatments include a new biological control agent. Hybrid elms and several new selections of American elm that show resistance to the disease have been developed.
