Description: In 2000, a previously unidentified Phytophthora isolated from rhododendrons in European nurseries and gardens was determined to be the same species – but a different population and mating type – as the pathogen causing sudden oak death in California. Upon recognizing the threats that P. ramorum posed to both wildlands and the nursery trade, countries around the world created quarantine programs to limit the introduction and spread of the pathogen. There are currently seven countries, plus the European Union, with quarantine regulations regarding P. ramorum. The E.U. quarantine required member states to survey for P. ramorum, and through November 2004, 13 European countries have detected P. ramorum in nurseries. Despite quarantine efforts 381 positive sites have been identified in the United Kingdom alone.

Keywords: Phytophthora ramorum, nursery, regulations, plant pathogen quarantines
