Susceptibility of silver birch and black alder to several Phytophthora species isolated from soils in declining broadleaf forests in western Ukraine

Matsiakh, Iryna; Lopez-Garcia, Noelia; Kacprzyk, Magdalena; Cleary, Michelle


In declining broadleaf forests in western Ukraine, several Phytophthora species including P. plurivora, P. bilorbang, P. polonica, P. gonapodyides and P. cactorum were recovered using soil baiting assays and identified using morphological and molecular methods. Pathogenicity tests of selected isolates were performed on black alder (Alnus glutinosa (L.) Gaerth.) and silver birch (Betula pendula Roth.) to assess susceptibility of these two tree species to the newly detected Phytophthora species. Phytophthora plurivora, P. bilorbang and P. polonica showed higher pathogenicity in both alder and birch compared to the other tested Phytophthora species.
