SUBJECT

This directive contains the phytosanitary requirements for the importation from the United States (US) and domestic movement of plants for planting of all Corylus spp. (filbert, hazelnut, cobnut), except seed for planting, to prevent the entry and spread of Eastern filbert blight (Anisogramma anomala (Pk.) Müller) into British Columbia (B.C.).

Introduction

Eastern filbert blight is caused by the fungus Anisogramma anomala and is devastating to cultivated Corylus avellana, causing a progressive cankering, loss of productivity, death of susceptible trees and associated increased costs of production. There is no known control method for this disease. Eastern Filbert Blight is transmitted by rain or wind dispersal of spores, or by human activity introducing infected materials into previously uninfected areas. Eastern filbert blight infects developing buds or those injured by mites. It is endemic to temperate eastern North America where it lives on wild filbert (Corylus americana) causing little or no damage. The province of B.C. is free of Eastern filbert blight and is separated from the nearest infested area in Washington state by mountain ranges. It does not occur outside North America. Corylus spp. from sources other than the U.S. and Canada may be subject to a Pest Risk Assessment (PRA).

The Plant Health Division has received requests to import tissue-cultured plantlets from the US to B.C. As Anisogramma anomala is a quarantine pest to B.C., all propagative Corylus spp. materials originating in the infested areas are prohibited entry to B.C. The requests received for tissue-cultured material prompted a PRA and subsequent review of the regulations governing such imports. The pest risk analysis concluded that the risk of introducing Eastern Filbert Blight into Canada with tissue-cultured Corylus is low, tissue-cultured Corylus plantlets will now be admissible into B.C..

This directive does not deal with nuts (cured or green). Corylus spp. nuts are regulated for filbert worm, Melissopus latiferreanus.

Scope

This directive is for the use of Canadian Importers and Shippers of Corylus, American Exporters of Corylus to Canada and Canadian Food Inspection Agency (CFIA) staff involved in inspection of Corylus.

3.0 Movement Requirements and Prohibitions

3.1 To the province of B.C.

3.1.1 Plants for planting from infested areas of the US and Canada (see Appendix 1):

Prohibited.

3.1.2 Plants for planting from non-infested areas of the US (and state or province not mentioned in Appendix 1):

Permit to Import and a Phytosanitary Certificate (for imports from the US) or a Domestic Movement Certificate (for domestic movement) are required. The Phytosanitary Certificate or the Domestic Movement Certificate must bear the following declaration:

“Material was grown in an area where, on the basis of official surveys, Eastern filbert blight disease (Anisogramma anomala) does not occur”.

3.1.3 Sterile tissue cultured plantlets for planting

3.1.3.1 Permit to Import and a Phytosanitary Certificate (for imports from the US) or a Domestic Movement Certificate (for domestic movement) are required. The Phytosanitary Certificate or the Domestic Movement Certificate must bear the following declaration;

“Material originated from mother stock free of Eastern filbert blight (Anisogramma anomala) and was grown in sterile medium.”

3.1.3.2 The plantlets must originate in a state or provincial program which was pre-approved in writing by the CFIA and has the following elements:

• The mother plants must be free of Eastern filbert blight disease based on visual surveys for the disease and the use of prophylactic spray applications as prescribed by the state or province; OR
• Areas from which the mother plants originate must be free of Eastern filbert blight disease based on official surveys and pre-approved by the CFIA AND
• Plants must be propagated by tissue culture, i.e. in vitro, and must be shipped as tissue cultured plants in sterile medium

3.2 To all provinces other the B.C.

3.2.1 Plants for planting and sterile tissue cultured plantlets from anywhere in the US

A Permit to Import and a Phytosanitary Certificate is required.

3.2.2. Movement within infested areas in Canada

No requirements.

4.0 Inspection Procedures

Pursuant to the work plan, CFIA inspectors will inspect and ensure that:

• for imports from the US, the Canadian importer holds a valid Permit to Import.
• for imports from the US, a Phytosanitary Certificate issued under the authority of the national plant protection organization accompanies the shipment and the appropriate additional declarations are stated is required.
• for domestic movement to B.C., a Movement Certificate is issued.
• for tissue-cultured plantlets, ensure that the shipment meets the requirements as stated in this directive and the plants are tissue-cultured plants.

5.0 Non-Compliance

Shipments which do not meet requirements, or are found to be infested with any quarantine pests may be refused entry, returned to origin, or disposed of at the importer's expense. If determined feasible by the inspector, such shipments may be rerouted to other destinations, provided such a course of action does not cause unwarranted pest risk.
