'Candidatus Phytoplasma ulmi'(PHYPUL)

Distribution details in Germany

Situation
Current pest situation evaluated by EPPO on the basis of information dated 2020: Present, widespread
Comments
Although 'elm yellows' observed in North America and Europe present different symptoms and disease severity, the phytoplasmas associated with them are very closely related (if not belonging to the same species).

EPPO Reporting Service (2009/217) : at least 1 phytoplasma strain was isolated near Stuttgart on U. glabra in the 1990s.

Schneider et al. (2020): ‘Candidatus Phytoplasma ulmi’ is widespread but symptoms of elm yellows are rarely observed.
