Dutch elm disease is a fatal fungus disease attacking American elms. The fungus is spread by European and native elm bark beetles and by root grafts (the growing together of roots of adjacent trees.) For preventive control and curative treatment measures to be effective, it is vital to understand how these measures work, to know how Dutch elm disease spreads, to be able to recognize initial symptoms of the disease, to know which trees may respond favorably, and how to make treatments properly, all of which is covered in this handy fact sheet (8 pages).
