Comments
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.
