Our File I. SUBJECT This directive contains the policy for domestic regulations pertaining to pear trellis rust, Gymnosporangium fuscum Hedw. f. This directive supersedes Quarantine Directive Domestic -3, dated 07/01/1986. II. BACKGROUND Pear trellis rust has been known for centuries as a disease of pears and junipers in Europe, Asia and North Africa. The pathogen is restricted to species of Pyrus, Pyronia, Juniperus and one species of Cupressus. Pear trellis rust probably entered North America through the importation of junipers from Europe. It has been regulated by Agriculture and Agri-Food Canada (AAFC) since 1972. AAFC currently has regulations which prohibit entry of plant and plant parts of Juniperus spp. for propagation from all countries and areas of the United States (U.S.) where pear trellis rust is known to occur. Pyrus spp. are prohibited from all countries where the disease is known to occur unless the pear material is defoliated and dormant at time of shipment. Pyrus spp. of U.S. origin are not subject to this requirement, except Pyrus spp. material originating from the infested area in California. Plants and plant parts for propagation (excluding seed) from origins that are not prohibited require a Permit to Import and a foreign Phytosanitary Certificate. III. LEGISLATIVE AUTHORITY Plant Protection Act, s.c. 1990, c.22 IV. POLICY AAFC is taking steps to deregulate pear trellis rust. Deregulation cannot occur until the amendment of the Plant Protection Regulations, SOR/95-212, is complete, a process which may take up to one year from the date of this memo. Import prohibitions, import requirements and domestic regulations pertaining to pear trellis rust remain in place until the deregulation process is completed. This policy explains the domestic movement requirements for pear trellis rust. In order to meet the requirements of the existing regulations for domestic movement, Movement Certificates have to be issued for Juniperus and Pyrus spp. from the infested area in British Columbia. Food Production and Inspection (FP&I) staff of AAFC will issue a master Movement Certificate to commercial growers. The maximum quantity of stock the certified grower intends to ship within this period should be indicated on the master copy. If actual consignments exceed the quantity indicated on the master Movement Certificate, the grower should contact FP&I staff of AAFC for an additional Movement Certificate to cover the excess. Photocopies of the certificate must accompany each consignment shipped domestically until the amendment passes or the expiry date of the Movement Certificate. The deregulation will be published in the Canada Gazatte II and covered by a Plant Protection Division policy directive. Dr. J.E. Hollebone
