Official Pest Reports

Official Pest Reports are provided by National Plant Protection Organizations within the NAPPO region. These Pest Reports are intended to comply with the International Plant Protection Convention's Standard on Pest Reporting, endorsed by the Interim Commission on Phytosanitary Measures in March 2002.

USA Flag Listing and Regulation of Plants Recently Reported with Phytophthora ramorum - United States
Date posted: 01/25/2008
Contact: National P. ramorum Program Manager, Jonathan Jones, at (301) 734-5038
On February 27, 2007, the USDA’s Animal Plant Health Inspection Service (APHIS) published an interim rule in the Federal Register for Phytophthora ramorum (ramorum blight, ramorum dieback, sudden oak death) (7 CFR 301.92). This rule regulates the interstate movement of restricted and regulated articles to prevent the artificial spread of this disease-causing organism from areas where the disease is established. This rule listed 105 hosts of P. ramorum.

The purpose of this Official Pest Report is to provide notification that as of January 1, 2008 APHIS is regulating certain new species for P. ramorum. This action is necessary because two new hosts were found naturally infected with P. ramorum (outside of the United States): Corylopsis spicata and Physocarpus opulifolius. These two taxa need to be regulated in order to control the artificial spread of this disease. No new hosts for P. ramorum were reported in the United States in 2007. In addition, APHIS is deleting an unnecessary listing of Kalmia angustifolia, since all species of Kalmia are being regulated. This deletion is consistent with the interim rule, as published.

For more information about current U.S. P. ramorum program and regulations please visit: http://www.aphis.usda.gov/plant_health/plant_pest_info/pram/index.shtml  

Under IPPC standards, Phytophthora ramorum is considered to be a pest that is present (localized in California and Oregon), under eradication in Oregon and subject to official control in the United States.
