Abstract
The Dutch Elm disease is caused by Ceratostomella ulmi (Schwartz) Buis (1); and, two types of elm bark beetles (9) are its vectors (3,4,9). Growth of the fungus occurs in the xylem tissue, which predominantly is concerned with conduction of water to the foliage. The spores and bud cells of C. ulmi are smaller than the elm wood vessels (1,2). C. ulmi, too, can be transmitted through root grafts.
