Sudden oak death regulations
What is SOD
SOD, short for Sudden Oak Death, is the common name for the federally quarantined pathogen, Phytophthora ramorum. P. ramorum was first observed in Marin County, California in 1995 on tanoak (Lithocarpus densiflorus). The pathogen now infects native hosts in 14 counties along California coast and in Curry County in southwestern Oregon, where it is established and has caused widespread dieback of tanoak and other oak species. P. ramorum has also been found infecting horticultural plants at nurseries in California, Oregon, and Washington. A complete host list for SOD is maintained by the United States Department of Agriculture, Animal and Plant Health Inspection Service (USDA, APHIS).

The Oregon Department of Agriculture (ODA) first began surveying Oregon nurseries for SOD in 2001, with the advent of the quarantine in Curry county. The pathogen was first found in 2003 at nurseries in Clackamas, Jackson, and Washington counties. Nursery crops infected included Camellia, Pieris, Rhododendron, and Viburnum species. The affected nurseries were placed on quarantine until all infected material was destroyed, delimitation surveys completed, and 90 day monitoring found no sign of the disease. In 2004, the pathogen was detected in 24 nurseries and the USDA confirmed nursery protocol was initiated for positive nurseries. Protocol included immediate quarantine of positive nurseries, delimitation surveys to assess the extent of the infection, destruction of all positive plant material, survey monitoring, trace forward surveys, and trace back surveys. On January 10, 2005, a USDA federal order went in effect, regulating the movement of nursery stock from Oregon, California, and Washington nurseries. The purpose of the order was to prevent the spread and dissemination of P. ramorum through the horticultural trade.

The USDA, APHIS quarantine for P. ramorum was established to prevent the spread of the pathogen. Nurseries that ship plants out of Oregon that are in the quarantine area of Curry county and any nursery that has been found positive for SOD within the past three years (on or after March 31, 2011) fall under this quarantine. These nurseries must enter into compliance with the USDA. For more information, please visit the USDA's P.ramorum website or contact the ODA, Plant Program at 503-986-4644.

Oregon nurseries approved to ship nursery stock out of state and not positive since March 31, 2011, will no longer be required to enter into compliance with the USDA. These nurseries will not have to use their federal shield after April 1, 2014. The ODA is required to maintain a list of nurseries who ship nursery stock out of state and who are, at least annually, inspected for the presence of P. ramorum. This list is maintained as up to date as possible. Contact ODA at 503/ 986-4644 if you have questions.

Oregon nurseries approved to ship nursery stock out of state

Recipients of tree and shrub nursery stock imported into Oregon from any out of state source are required to notify the ODA. This information assists ODA personnel in monitoring of SOD host material imported to Oregon as well as plant material of other quarantine concern. Notification shall be via mail (Nursery Program Supervisor, Plant Division, Oregon Department of Agriculture, 635 Capitol St. NE, Salem, OR 97301), FAX (503-986-4564) or e-mail (quarantine@oda.state.or.us ).
