The Panel on Plant Health performed a pest categorisation of the causal agent of fruit rot and wart bark on apple and pear, for the EU. The pathogen, which was recently characterised, is a well-defined fungal species affecting mainly (Japanese pear) although (European pear) and apples () can also be affected. The host status of other plant species reported in the literature, i.e. and spp., is unclear. . is currently present in Japan, China, Korea, Taiwan and the USA, and uncertainty exists about its presence in other areas, where the disease has been associated with other spp. The pathogen is not known to occur in the EU and is listed in Annex IIAI of Directive 2000/29/EC. It could potentially enter the EU on host plants for planting and fruit originated in infested countries. Climatic conditions in the EU are suitable for the establishment and spread of the pathogen, as its epidemiology is similar to that of other spp. present in the EU. Pears and apples are widely distributed in the EU. In the infested areas, causes branch dieback and fruit rot resulting in yield/quality losses. Its introduction and spread in the EU could impact pear and apple production, although the magnitude is unknown. Cultural practices and chemical measures may reduce the inoculum sources but cannot eliminate the pathogen. Phytosanitary measures are available to mitigate the risk of introduction and spread of the pathogen in the EU. meets all criteria assessed by EFSA for consideration as a potential Union quarantine pest. As is not known to occur in the EU, this criterion to consider it as a Union regulated non-quarantine pest is not met.
植物健康小组针对欧盟地区对苹果和梨上果实腐烂及树皮疣病的致病因子进行了有害生物风险分析。这种病原体最近已得到鉴定，是一种明确的真菌物种，主要影响（日本梨），不过（欧洲梨）和苹果（）也可能受到影响。文献中报道的其他植物物种，即和 spp. 的寄主状况尚不清楚。目前在日本、中国、韩国、台湾和美国存在，在其他地区其存在情况尚不确定，在这些地区该病害与其他 spp. 有关。已知该病原体在欧盟不存在，且被列入2000/29/EC号指令附件IIAI中。它有可能通过来自受侵染国家的种植用寄主植物和果实进入欧盟。欧盟的气候条件适合该病原体的定殖和传播，因为其流行病学与欧盟现有的其他 spp. 相似。梨和苹果在欧盟广泛分布。在受侵染地区，会导致枝条枯死和果实腐烂，从而造成产量/质量损失。它在欧盟的传入和传播可能会影响梨和苹果的生产，尽管影响程度未知。栽培措施和化学防治措施可能会减少接种源，但无法消除病原体。可采取植物检疫措施来降低该病原体在欧盟传入和传播的风险。符合欧洲食品安全局评估的作为潜在欧盟检疫性有害生物的所有标准。由于已知在欧盟不存在，因此不符合将其视为欧盟管制的非检疫性有害生物的这一标准。
