The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as 'High risk plants, plant products and other objects'. This Scientific Opinion covers all plant health risks posed by dormant and free of leaves, 1- to 3-year-old bare root plants for planting of spp. imported from New Zealand, taking into account the available scientific information, including the technical information provided by New Zealand. The relevance of an EU-quarantine pest for this opinion was based on evidence that: (i) the pest is present in New Zealand; (ii) spp. are hosts of the pest and (iii) the pest can be associated with the commodity. The relevance for this opinion of any other pest, not regulated in the EU, was based on evidence that: (i) the pest is present in New Zealand; (ii) the pest is absent from the EU; (iii) spp. are hosts of the pest; (iv) the pest can be associated with the commodity and (v) the pest may have an impact and can pose a potential risk for the EU territory. Four pests (, , and ) that fulfilled all relevant criteria were selected for further evaluation. For the selected pests, the risk mitigation measures proposed in the technical dossier from New Zealand were evaluated taking into account the possible limiting factors. For the selected pests, an expert judgement is given on the likelihood of pest freedom taking into consideration the risk mitigation measures acting on the pest, including uncertainties associated with the assessment. Based on the outcome of Expert Knowledge Elicitation, the degree of pest freedom varies among the pests evaluated. The mite, , was the pest most likely to cause plants to fail pest freedom status. The Panel is 95% sure that at least 9,240 plants per 10,000 will be free from .
欧盟委员会要求欧洲食品安全局植物健康小组针对欧盟委员会实施条例（EU）2018/2019中列为“高风险植物、植物产品及其他物品”的商品编写并提供风险评估。本科学意见涵盖从新西兰进口的1至3年生休眠且无叶裸根种植用 属植物所带来的所有植物健康风险，同时考虑了现有科学信息，包括新西兰提供的技术信息。对于本意见而言，一种欧盟检疫性有害生物的相关性基于以下证据：（i）该有害生物存在于新西兰；（ii） 属植物是该有害生物的寄主；（iii）该有害生物可与该商品相关联。对于欧盟未进行监管的任何其他有害生物，本意见的相关性基于以下证据：（i）该有害生物存在于新西兰；（ii）该有害生物在欧盟不存在；（iii） 属植物是该有害生物的寄主；（iv）该有害生物可与该商品相关联；（v）该有害生物可能产生影响并可能对欧盟领土构成潜在风险。选择了符合所有相关标准的四种有害生物（ 、 、 和 ）进行进一步评估。对于选定的有害生物，考虑到可能的限制因素，对新西兰技术档案中提出的风险缓解措施进行了评估。对于选定的有害生物，在考虑针对该有害生物的风险缓解措施（包括评估相关的不确定性）的情况下，对有害生物无疫情可能性给出了专家判断。根据专家知识启发的结果，在所评估的有害生物中，无疫情程度各不相同。螨类 是最有可能导致植物无法达到无有害生物状态的有害生物。小组有95%的把握确定每10,000株植物中至少有9,240株将无 。
