Pest free potato (Solanum spp.) micropropagative material and minitubers for international trade.
Definitions of phytosanitary terms can be found in ISPM 5 (Glossary of phytosanitary terms). In addition to definitions in ISPM 5, in this standard the following definitions apply:
potato micropropagative material Plants in vitro of tuber-forming Solanum spp.
minituber A tuber produced from potato micropropagative material in pest-free growing medium in a facility under specified protected conditions seed potatoes Tubers (including minitubers) and potato micropropagative material of cultivated tuber-forming Solanum spp. for planting
Outline of Requirements Facilities used for the production of potato micropropagative material and minitubers for export should be authorized or operated directly by the national plant protection organization (NPPO) of the exporting country. Pest risk analysis (PRA), carried out by the NPPO of the importing country, should provide the justification for establishing phytosanitary import requirements for regulated pests in trade of potato micropropagative material and minitubers. The phytosanitary measures for managing risks related to potato micropropagative material include testing for the pests regulated by the importing country, and management systems for the maintenance and propagation of potato micropropagative material derived from candidate plants that have been determined to be pest free in closed, aseptic conditions. For the production of minitubers, measures include derivation from pest free potato micropropagative material and production in a pest free production site. To establish pest free potato micropropagative material, candidate plants should be tested in a testing laboratory authorized or operated directly by the NPPO. This laboratory should meet general requirements for ensuring that all material moved into a maintenance and propagation facility is free from pests regulated by the importing country.
Facilities for the establishment of pest free potato micropropagative material and testing for pest freedom are subject to strict requirements to prevent contamination or infestation of material. Facilities for maintenance and propagation of pest free potato micropropagative material and minituber production are also subject to stringent requirements to maintain pest freedom. Staff should be trained and competent in techniques for the establishment and maintenance of pest free potato micropropagative material, the production of pest free minitubers, diagnostic testing as required, and in following administrative, management and record-keeping procedures. The management system and procedures of each facility and the testing laboratory should be defined in a manual(s). Throughout all production and testing processes, the identity of all propagative material should be preserved, and traceability should be maintained through adequate documentation. All facilities should be officially audited to ensure that they continue to meet requirements. In addition, inspections should ensure that the potato micropropagative material and minitubers meet the importing country’s phytosanitary import requirements. Pest free potato micropropagative material and minitubers moving in international trade should be accompanied by a phytosanitary certificate.
This standard provides guidance on the production, maintenance and phytosanitary certification of pest free potato (Solanum tuberosum and related tuber-forming species) micropropagative material and minitubers intended for international trade. This standard does not apply to field-grown propagative material of potato or to potatoes intended for consumption or processing.
