The USDA’s Animal and Plant Health Inspection Service (APHIS) has updated its earlier report of an outbreak of Phytophthora ramorum, the highly infectious pathogen that causes sudden oak death. The pathogen has been detected on more than 50 rhododendrons, which were part of a larger shipment that went to 18 states, according to a release by the service.

The service has confirmed that nursery stock tested positive at nursery establishments in eight states: include Iowa, Illinois, Indiana, Kansas, Missouri, Nebraska, Oklahoma, and Washington. The infested plants were traced to nurseries in Canada and the state of Washington.
