From CABI Disease map 978 (2022): Present, restricted distribution
EPPO Reporting Service (2003/133) : found once on Rhododendon in 2002 on imported plants.
EPPO Reporting Service (2007/095) : through 2004 and 2005, found many more times on imported plants, and also in nurseries and gardens. Under eradication. Since most host plants offered for sale are imported, it is not clear whether P. ramorum is persisting from year to year in Norway, or simply being re-introduced.
VKM (2023): mainly being detected in the southern and southwestern parts of Norway. The only P. ramorum lineage considered to be present in Norway is EU1 with mating type A1.
