Description: For a scientist, my title may seem a little sensationalist in tone. This is deliberate - to draw attention to my issue. And hereÂ’s the issue. About six years ago the previously unknown invasive pathogen P. ramorum sp. nov. was found spreading on trees and shrubs in North America and Europe. Almost simultaneously in the U.K. we found another previously unknown invasive Phytophthora on trees and shrubs, P. kernoviae sp. nov. Shortly efore that we found the previously unknown invasive P. alni sp. nov. spreading on alders; and a decade before that the invasive P. ilicis on hollyÂ… Four invasive Phytophthora species, each spreading for some years prior to their discovery. And thatÂ’s just the Phytophthora species.Â… And thatÂ’s just the invasive Phytophthora species weÂ’ve actually found.

Keywords: Phytophthora ramorum, P. kernoviae, biosecurity, plant health
