Following a request from the EU Commission, the Panel on Plant Health performed a categorisation of beet necrotic yellow vein virus (BNYVV), the causal agent of the sugar beet rhizomania disease. The virus is currently listed in Annex III as a protected zone (PZ) quarantine pest of the Commission Implementing Regulation (EU) 2019/2072. The identity of the BNYVV is well established. BNYVV is a soil-borne virus transmitted by the obligate root plasmodiophorid endoparasite . BNYVV is widely distributed in the EU, but is not reported in the following EU PZs: Ireland, France (Brittany), Portugal (Azores), Finland and Northern Ireland. The virus may enter, become established and spread in the PZs via resting spores with soil and growing media as such or attached to machinery and with roots and tubercles of species other than and with plants for planting. Introduction of BNYVV would have a negative impact on sugar beet and other beet crops in PZs, because of yield and sugar content reduction. Phytosanitary measures are available to reduce the likelihood of entry and spread in the PZs. Once the virus and its plasmodiophorid vector have entered a PZ, their eradication would be difficult due to the persistence of viruliferous resting spores in the soil. The main knowledge gaps or uncertainties identified concerning the presence of BNYVV in the PZs and the incidence and distribution of BNYVV in Switzerland, a country to which a range of specific requirements do not apply. BNYVV meets all the criteria that are within the remit of EFSA to qualify as a potential protected zone union quarantine pest. Plants for planting are not considered as a main means of spread, and therefore BNYVV does not satisfy all the criteria evaluated by EFSA to qualify as potential Union regulated non-quarantine pest.
应欧盟委员会的要求，植物健康小组对甜菜坏死黄脉病毒（BNYVV）进行了分类，该病毒是甜菜根瘤病的病原体。该病毒目前被列入欧盟委员会实施条例（EU）2019/2072附件III中的保护区（PZ）检疫性有害生物。BNYVV的特性已得到充分确证。BNYVV是一种土传病毒，由专性根肿菌内生寄生虫传播。BNYVV在欧盟广泛分布，但在以下欧盟保护区未被报告：爱尔兰、法国（布列塔尼）、葡萄牙（亚速尔群岛）、芬兰和北爱尔兰。该病毒可能通过带有土壤和生长介质的休眠孢子进入保护区并定殖和传播，这些孢子附着在机械上，或附着在除[相关物种]以外的其他物种的根和块茎上，以及随种植植物进入。引入BNYVV会对保护区内的甜菜和其他甜菜作物产生负面影响，因为会导致产量和含糖量降低。可以采取植物卫生措施降低其进入和在保护区传播的可能性。一旦该病毒及其根肿菌传播介体进入保护区，由于带毒休眠孢子在土壤中的持久性，根除它们将很困难。关于BNYVV在保护区的存在以及在瑞士的发生率和分布情况，确定了主要的知识空白或不确定性，瑞士有一系列特定要求不适用于该国。BNYVV符合欧洲食品安全局（EFSA）职权范围内的所有标准，有资格成为潜在的保护区联盟检疫性有害生物。种植植物不被视为主要传播途径，因此BNYVV不完全满足EFSA评估的作为潜在联盟管制的非检疫性有害生物的所有标准。
