Pest categorisation of potato virus Y (non-EU isolates).

ABSTRACT: Following a request from the EU Commission, the Panel on Plant Health has addressed the pest categorisation of non-EU isolates of potato virus Y (PVY). The information currently available on geographical distribution, biology, epidemiology, potential entry pathways and potential additional impact of non-EU isolates of PVY, has been evaluated with regard to the criteria to qualify as a potential Union quarantine pest. Because non-EU isolates of PVY are absent from the EU, they do not meet one of the requirements to be regulated as a regulated non-quarantine pest (RNQP) (presence in the EU); as a consequence, the Panel decided not to evaluate the other RNQP criteria for these isolates. Populations of PVY can be subdivided into several strains and groups of isolates: strain C (PVY-C), strain N (PVY-N), strain O (PVY-O) and a wide range of recombinant isolates (PVY-recombinants) which have a worldwide distribution (including the EU). Two groups of isolates, i.e. the Brazilian (PVY-Br) and Chilean (PVY-Ch) isolates, are considered absent from the EU. Non-EU isolates of PVY-C, PVY-N, PVY-O and PVY-recombinants identified so far are not expected to have an additional impact in the EU compared to the PVY isolates already present and, therefore, do not meet the corresponding criterion to qualify as a potential Union quarantine pest. The Panel is unable to conclude on the potential additional impact of isolates of PVY-Br and PVY-Ch in the EU territory, but these isolates meet all the other criteria to qualify as potential Union quarantine pests.

Project description:Following a request from the EU Commission, the Panel on Plant Health has addressed the pest categorisation of those viruses and viroids (hereafter referred to as viruses) of Solanum tuberosum and other tuber-forming Solanum spp. (hereafter referred to as potato) which are considered to be either non-EU or of undetermined standing based on a previous EFSA opinion. These viruses belong to different families and genera and either have an established identity or produce consistent symptoms. Plants for planting is the main pathway for entry for all categorised viruses as they can all be transmitted by vegetative propagation. Several categorised viruses have a relatively wide host range and/or are vector-transmitted, increasing the potential for entry. The information currently available on geographical distribution, biology, epidemiology, impact and potential entry pathways has been evaluated with regard to the criteria to qualify as potential Union quarantine pest or as Union regulated non-quarantine pest (RNQP). Since this opinion addresses specifically the non-EU potato viruses, in general these viruses do not meet the criteria assessed by EFSA to qualify as potential Union regulated non-quarantine pests. The following viruses meet the criteria to qualify as potential Union quarantine pest: APLV, APMMV, APMoV, ChiLCV, CYSDV, PAMV, PBRSV, PVH, PVP, PVT, PYDV, PYMV, PYV, PYVV, RCVMV, SALCV, SB26/29, ToCV, ToLCNDV, ToMHaV, ToMoTV, ToSRV and ToYVSV. With the exception of the criterion regarding the potential for consequences in the EU territory, for which the Panel is unable to conclude because of lack of information, AVB, CPSbV, PaLCrV, PapMV, PVB, PVU, SB41 and TVBMV meet all the other criteria to qualify as potential Union quarantine pest. PotLV and WPMV do not qualify as potential Union quarantine pest, since they are not reported to have any impact. For most of the categorised viruses, the conclusions of the Panel have inherent uncertainties, due to the lack of quantitative data on their impact and/or absence or limited availability of information on the biology, epidemiology and geographical distribution.
