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 plant health risks posed by plants of the evergreen and the semi-evergreen imported from the United Kingdom (UK) as: (a) bare root plants and (b) plants in pots, taking into account the available scientific information, including the technical information provided by the UK. The category (a) 'bare root plants' includes bundles of 1- to 3-year-old bare root whips or transplants and single 1- to 7-year-old bare root plants. The category (b) 'plants in pots' includes bundles of 1- to 2-year-old cell grown plants (only ) and 1- to 5-year-old plants in pots. All pests associated with the commodities were evaluated against specific criteria for their relevance for this opinion. Two EU quarantine pests, and , and one pest not regulated in the EU, , fulfilled all relevant criteria and were selected for further evaluation. For the selected pests, the risk mitigation measures proposed in the technical dossier from the UK were evaluated taking into account the possible limiting factors. For these pests, an expert judgement is given on the likelihood of pest freedom considering the risk mitigation measures acting on the pest, including uncertainties associated with the assessment. In the assessment of risk, the age of the plants was considered, reasoning that older trees are more likely to be infested mainly due to longer exposure time and larger size. The degree of pest freedom varies among the pests evaluated, with being the pest most frequently expected on the imported plants. The Expert Knowledge Elicitation indicated with 95% certainty that between 9915 and 10,000 per 10,000 bare root plants and plants in pots will be free from .
欧盟委员会要求欧洲食品安全局植物健康小组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”的商品进行风险评估并提交报告。本科学意见涵盖从英国进口的常绿和半常绿植物所带来的植物健康风险，这些植物包括：(a) 裸根植物和 (b) 盆栽植物，评估时考虑了现有科学信息，包括英国提供的技术信息。类别 (a)“裸根植物”包括1至3年生裸根枝或移栽苗束以及单株1至7年生裸根植物。类别 (b)“盆栽植物”包括1至2年生穴盘苗束（仅）和1至5年生盆栽植物。针对与这些商品相关的所有有害生物，依据与本意见相关的特定标准进行了评估。两种欧盟检疫性有害生物，即[有害生物名称1]和[有害生物名称2]，以及一种在欧盟未受管制的有害生物，即[有害生物名称3]，满足所有相关标准并被选作进一步评估对象。对于选定的有害生物，考虑到可能的限制因素，对英国技术档案中提出的风险缓解措施进行了评估。对于这些有害生物，在考虑作用于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，就是否可能不存在有害生物给出了专家判断。在风险评估中，考虑了植物的年龄，理由是树龄越大，受侵染的可能性越高，主要是因为暴露时间更长且植株更大。在所评估的有害生物中，不存在有害生物的程度各不相同，[有害生物名称1]是进口植物上最常预期出现的有害生物。专家知识启发法以95%的确定性表明，每10,000株裸根植物和盆栽植物中，有9915至10,000株将不存在[有害生物名称1]。
