Subject

This directive contains the phytosanitary requirements to prevent the introduction of Dutch elm disease, Ophiostoma ulmi (Buisman) Nannf. and Ophiostoma novo-ulmi Brasier, from the United States (U.S.) and infested areas of Canada into uninfested areas of Canada. This directive regulates commodity pathways and therefore governs the movement of propagative material, including nursery stock, and non-propagative material with bark attached such as logs, lumber, firewood, crates and isolated bark of all species, hybrids and horticultural cultivars of elm (Ulmus spp. and Zelkova spp.)

This directive has been revised to strengthen the phytosanitary requirements pertaining to the domestic movement and importation of some regulated commodities such as elm nursery stock from infested areas of Canada and the U.S.

Introduction

Dutch elm disease is a serious disease of elms in almost every country where elm is grown or is native. Dutch elm disease was first discovered in Canada in 1944. It has killed millions of trees in Canada and cost millions of dollars annually to control.

The major methods for the disease to spread are through the following bark beetle vectors: the native bark beetle Hylurogopinus rufipes (Eichh.), the European elm bark beetle Scolytus multistriatus (Marsh.), and most recently, the banded elm bark beetle Scolytus schevyrewi (Semenov), and the movement of elm trees, logs and firewood. Unbranched young trees of elm varieties grown to a length of two metres (79 inches) or less and no larger than 1.27 cm (½ inch) in diameter pose less risk of carrying the Dutch elm disease fungus, especially if produced from disease-free stock initially. This is because beetle feeding or breeding necessary to introduce the Dutch elm disease fungus is unlikely to occur on unbranched material of this size or smaller. Trees of this size are expected to be free of Dutch elm disease provided that they were produced from disease-free stock initially.

The most effective control measure is the control of movement of elm material. The provinces of Alberta, Nova Scotia, Manitoba, and Saskatchewan have provincial regulations in place to control the introduction or spread of Dutch elm disease into their provinces.

The disease occurs in all provinces except British Columbia, Alberta and Newfoundland and Labrador. The European Elm Bark Beetle Scolytus multistriatus (Marsh.) has been trapped in British Columbia and Alberta. However, the disease has not been reported in either province except for an isolated find of Dutch elm disease in Wainwright, Alberta in 1999 that was removed and destroyed, further surveys have not detected any Dutch elm disease since.

Scope

This directive is intended for the use of the CFIA inspection staff, Canada Border Service Agency, Canadian importers and national plant protection organizations, industry and the public. The directive outlines the necessary requirements and inspection procedures for the importation of and domestic movement of elm (Ulmus spp. et Zelkova spp.) material.

This directive supersedes D-97-07 (Original); Quarantine Directive Domestic-8, dated 1985-12-31 (amended 1991-03) and any reference to the subject of domestic movement of elm material concerning Dutch elm disease in any other document.

3.0 Material for Research

There has been interest in testing the winter hardiness of some Ulmus spp. and or Zelkova spp. varieties. The CFIA may approve the importation of propagative and or non-propagative Ulmus spp. and or Zelkova spp. material from the U.S. and partially infested and generally infested provinces of Canada for research. Any proposed research material originating in the U.S. and moving to in non-infested areas of Canada will require CFIA approval via a CFIA issued Permit to Import under section 43, of the Plant Protection Regulations for research purposes only. Any proposed research material originating in generally or partially infested provinces of Canada will require a CFIA issued Movement Certificate for research purposes only. The applicant must also submit a detailed research plan. The research must take place in a CFIA accredited level 2 or higher plant containment facility. Any required certificate or Permit to Import will be issued by the CFIA in consultation with the affected province.

4.0 Firewood

Within this policy directive firewood is regulated as non-propagative material and may be subject to additional requirements as per directive D-01-12, Phytosanitary requirements for the importation and domestic movement of firewood.

5.0 Inspection Procedures and Reference Information

Phytosanitary and Movement Certificate(s) must be verified. Material with Dutch elm disease vectors or symptoms of Dutch elm disease will be refused entry, destroyed or returned to origin at importer's expense. Material must be free of all quarantine pests and substantially free of other injurious pests. Forestry products are subject to verification for freedom from bark.

Dutch elm disease signs and symptoms are extremely difficult to detect on logs, firewood and young branchless nursery stock. Below is a generic description of Dutch elm disease symptoms in live trees with leaves and associated sampling procedures.

Infected elm trees show symptoms as early as mid June such as wilting leaves that turn yellow, then curl and turn brown. Symptoms usually appear in the crown of the tree and can be seen until fall colours appear. Sometimes the curls, brown leaves will remain on the tree throughout winter. Trees that become infected later in the summer can cause tree leaves to turn yellow and fall prematurely much like normal fall colouration.

If the presence of Dutch elm disease is suspected collect samples from the branch showing symptoms, peel back the bark and look for brown staining in the sap wood. If brown staining is found, remove another section of the branch, try to get a sample that is smooth and straight, lacking any cankers, and is not dried out or dead. Cut this branch into 5 pieces that are 10-15 mm long and 2 cm in diameter. Do not remove the bark but remove the leaves and twigs. These samples can be submitted for lab analysis to confirm the presence of Dutch elm disease.

6.0 Non-Compliance

Shipments not meeting the import and domestic movement requirements of this directive will be refused entry, returned to origin or destroyed at owner's expense.
