Draft ISPM: International movement of seeds (2009-003)

This draft discusses the challenges associated with the international movement of seeds and the phytosanitary measures that need to be implemented to prevent the introduction and spread of pests. It addresses issues such as seed certification, resistant varieties, treatments, and pest risk management. The draft also highlights the importance of establishing equivalent phytosanitary measures for seeds re-export.

  1. Draft ISPM: International movement of seeds(2009-003) IPPC Member Consultation 1 July to 30 November 2014

  2. Background • Seeds are moved internationally to be planted for food and ornamentals but also for other uses (research, breeding, seed increase, etc.) • Challenges include re-export to numerous countries and over an extended period of time. • Seeds are subject to phytosanitary issues, such as diverse import requirements, diagnostic and inspection methodologies, and measures that cannot be fulfilled retrospectively (e.g. field inspections).

  3. General Considerations PRAs should identify the regulated pests associated with seeds and the relationship between the intended use and the potential for quarantine pests to establish. Risk of introducing a regulated pest is higher when seeds are for planting. Seed-borne pests may be found on the seed internally or externally, and may or may not be transmitted to the plant progeny, and if it does, it may not result in infestation.

  4. General Considerations (2) Phytosanitary measures may include seed certification schemes; use of resistant varieties; PFAs; treatments; pest risk management during seed production; PEQ; and prohibition. Establishing equivalent phytosanitary measures is particularly important for seeds re-export. Because seeds may be stored for many years before export, phytosanitary records should be kept for a minimum of 5 years.

  5. Drafting issues Standard applies to true seeds only (botanical seeds). Seed as a pathway: seed-borne and seed transmitted pests considered. Definitions added to the standard. The standard includes guidance for contaminating pests (e.g. weed seeds). The standard distinguishes the intended use between seeds not for planting and seeds for planting. Large vs small lots of seeds. Experts considered these and included guidance for both.

  6. Drafting issues Only pests identified in the PRA as having potential to lead to establishment after entry should be considered for phytosanitarymeasures. Two areas of concern for phytosanitary certification: harmonization of additional declarations and import requirements for re-exports. Equivalency of phytosanitary measures is considered critical for allowing seeds to re-export. Some information on coated seeds is included.

  7. Drafting issues Use of the following terms: • seeds vs seed. Seeds refers to the commodity class whereas seed is used more in the botanical sense. • pest transmitted vspest transferred. The text uses “pest that can be transmitted” because it fits better both concepts of seed-borne and seed-transmitted pests. • regulated pests was used in relation to establishment, because regulated non-quarantine pests would already be established in the area. • devitalized seed may not fit the glossary definition of seed but the concept was still retained in the draft.

  8. Drafting issues Weed seeds questioned as contaminating pests because when the pest is present in the field it is considered an infestation and weed seeds are not contaminating pests. The term was retained because in ISPM 5, weed seeds are included in the glossary definition for contaminating pest. Groups of pests associated with seeds were deemed helpful information and it was included in an Annex.

  9. Other relevant information • A proposed Annex on forest tree seeds will be developed by the Technical Panel on Forest Quarantine and presented separately to the Standards Committee.
