1	Histochemical studies on the pathogenesis of the elm disease incited by Ceratocystus Ulmi (buism.) C. Moreau in Ulmus Americana L. Gagnon, Camilien Joseph Xavier. January 1965 (has links) The elm disease incited by Ceratocystis ulmi (Buism.) C. Moreau, generally named Dutch elm disease, especially in North America, was discovered in The Netherlands soon atter the first world war. The designation, Dutch elm disease, should be avoided, according to Westenberg (1932), because it is misleading. The name elm disease is used in this work, following in this respect the nomenclature adopted in the Annual Report of the Quebec Society for the Protection of Plants (Pomerleau, 1961).
