Domestic Quarantine for

Phytophthora ramorum 7 CFR 301.92



December 10, 2012



The purpose of this Federal Order is to prevent the spread of harmful plant diseases caused by P. ramorum, through regulatory authority pursuant to the Plant Protection Act of June 20, 2000, as amended, Section 412(a), 7 U.S.C. 7712(a), which authorizes the Secretary of Agriculture to prohibit or restrict the movement in interstate commerce of any plant, plant part, or article if the Secretary determines the prohibition or restriction is necessary to prevent the dissemination of a plant pest within the United States.


This Federal Order supersedes all previous Federal Orders pertaining to Phytophthora ramorum notification including the January 28, 2011 (DA-2011-04) and the subsequent Federal Order dated February 25, 2011 (DA-2011-10). The Animal and Plant Health Inspection Service (APHIS) issued the above-referenced Federal Orders to require certain nurseries in quarantine and regulated areas to provide advance notification for shipments of P. ramorum high-risk host nursery stock. This Federal Order amends the requirements for nurseries in the regulated areas and describes the timeframe for maintaining records.


APHIS is taking this action based on the findings of the advance notification review and additional information provided by State Regulatory Authorities and industry stakeholders. The review findings indicated that the advance notification requirement, in its current form, did not meet the established goals of providing non-regulated states sufficient information to allow them to prioritize resources and assure rapid response.


Currently, nurseries shipping interstate high-risk nursery stock of Camellia, Kalmia, Pieris, Rhododendron (including Azalea), and Viburnum (as defined under 7CFR 301.92-2) from quarantine areas in California and Oregon must provide written notification to the non-regulated states. In addition, nurseries shipping interstate high-risk nursery stock located in several regulated areas in California, Oregon and Washington have to notify whether or not P. ramorum has been detected on their premises.


The amended Federal Order will require any nursery located in the current quarantined counties shipping interstate any species of the genera Camellia, Kalmia, Pieris, Rhododendron (including Azalea), and Viburnum (defined under 7 CFR 301.92-2 (d) proven host taxa) to non-regulated areas, to continue providing notification to destination states. In the regulated areas, however the amended Federal Order will apply only to specific nurseries that are currently positive for P. ramorum or have tested positive for P. ramorum over the last 3 years (since 2010). In addition, if P. ramorum is detected in the future, for example, during nursery certification surveys or surveys resulting from trace investigations, these nurseries will also be required to provide notifications. Therefore, nurseries located in a regulated county that have never detected P. ramorum on their premises or have tested negative for P. ramorum for the last consecutive 3 years are no longer required to provide notification. This amendment to the Federal Order will assist both APHIS and State Regulatory Agencies to refocus their resources on nurseries located in quarantine areas and those high-risk nurseries where P. ramorum has been detected, while minimizing the burden on the nursery industry.


Effective immediately, any nursery located in the current quarantined counties shipping interstate any species of the genera Camellia, Kalmia, Pieris, Rhododendron (including Azalea), and Viburnum (defined under 7 CFR 301.92-2 (d) proven host taxa) to non-regulated areas, must continue to provide notification to destination states. The current quarantined counties are:


California: Alameda, Contra Costa, Humboldt, Lake, Marin, Mendocino, Monterey, Napa, San Francisco, San Mateo, Santa Clara, Santa Cruz, Solano, and Sonoma


Oregon: Curry.


Effective immediately, only previously or newly positive nurseries in the regulated areas of California, Oregon, and Washington shipping interstate any species of the genera Camellia, Kalmia, Pieris, Rhododendron (including Azalea), and Viburnum will be required to notify. This revised Federal Order removes notification requirements for nurseries in counties within regulated areas that have never tested positive for P. ramorum or have tested negative for the past three years.


APHIS and the State Regulatory Agencies in the regulated states will jointly review regulatory history (presence or absence of P. ramorum) of nurseries in the regulated areas to determine if they will be affected by this revised Federal Order and if they do, the nurseries that need to comply will be notified by their respective State Regulatory Agency. In addition, nurseries affected by the Federal Order must provide notification while under the Confirmed Nursery Protocol, and for two years after their release. APHIS will provide trace information to non-regulated states. Notifications will serve as an additional source of information for states receiving high-risk P. ramorum host nursery stock.


Notification of an outgoing shipment must be received by the State Plant Regulatory Agency before the shipment arrives at its destination. Nurseries may send notifications by mail, facsimile, or email. The requirement is satisfied by providing a bill of sale, manifest, or other forms of documentation that includes the following information:


• Name, telephone number, and address of the consignee;

• Name, telephone number, and address of the shipper;

• Plant name, number of each plant species/variety shipped;

• Mode of transportation (air, courier, ground); and

• Date of shipment


Nurseries within the regulated areas affected by this Federal Order and all interstate shippers of the five high-risk host plants in the quarantine areas are required to maintain notification records for a period of 1 year from the notification date to assist with assessing compliance. If nursery stock shipments arrive to the non-regulated state(s) without notification due to technical problems or emergencies, or arrive with errors, the shipping nurseries have 3 business days from the day the shipment(s) arrives to its destination to provide appropriate notification and explanation. If after the third business day neither the notification(s) nor explanation for non-compliance is provided, the receiving state may return the shipment to the point of origin or shipments may be destroyed at the shipper’s expense. Failure to comply with the Federal Order or compliance agreement issued under the Federal Order could result in suspension or revocation of the compliance agreement. APHIS State Plant Health Directors from the receiving state and the APHIS P. ramorum National Operations Manager will assist State Regulatory Agencies when there are issues related to non-compliance.


Affected nurseries with new positive detections are required to provide APHIS with trace forward information (i.e., interstate shipment details of the positive plant species/cultivar and of any high-risk genera for the previous 1-year from the date of detection) within 10 business days. APHIS will provide trace information to the receiving states. While carrying out the functions specified in this Federal Order, the receiving states must follow procedures consistent with Federal regulations, which are detailed in 7 CFR 301.92.
