Organisms included in the lists - The ISTA Reference Pest List includes bacteria, fungi, oomycetes, virus and nematodes pathogenic to seed crops. - Pests without a scientific evidence that they are seed-borne are not included in the ISTA Reference Pest List. They could be included once evidence will be proven. - Some saprotrophs are also included when scientific literature illustrates their seed-borne status, but for those organisms, the final decision about seed as a pathway of dissemination is not applicable (N/A), as they do not induce diseases. - In case of emerging pests, they could be included in the lists as soon as they are suspected to be at risk for seed trade, even if their seed-borne, and eventually seed-transmitted status is not fully stated. In these cases, literature survey will be conducted to share the most up-to-date knowledge and it will be indicated in the lists (pest categorization under investigation). No evidence list (new) - This list contains pests that were included in the last version of the Annotated list of seed-borne diseases (4th ed.; 1990), but that lack evidence of seed-borne status in the scientific literature. These pests will be regularly checked for information on their abilitiy to be seedborne. |
