Following a request from the EU Commission, the Panel on Plant Health addressed the pest categorisation
of the viruses and viroids of Fragaria L. determined as being either non-EU or of undetermined standing
in a previous EFSA opinion. These infectious agents belong to different genera and are heterogeneous in
their biology. With the exclusion of strawberry latent virus and strawberry latent C virus for which very
limited information exists, the pest categorisation was completed for 12 viruses having acknowledged
identities and available detection methods. All these viruses are efficiently transmitted by vegetative
propagation techniques, with plants for planting representing the major pathway for long-distance
dispersal and thus considered as the major pathway for entry. Depending on the virus, additional
pathway(s) can also be Fragaria seeds, pollen and/or vector(s). Most of the viruses categorised here are
known to infect only one or few plant genera, but some of them have a wide host range, thus extending
the possible entry pathways. Strawberry chlorotic fleck-associated virus, strawberry leaf curl virus,
strawberry necrotic shock virus, strawberry pallidosis-associated virus, strawberry vein banding virus
(SVBV) and tomato ringspot virus meet all the criteria evaluated by EFSA to qualify as potential Union
quarantine pests (QPs). For SVBV, the Panel considered that following its entry and establishment into the
EU territory, an impact of uncertain magnitude is expected mainly because a synergistic effect may occur
in strawberry in case of mixed infections with viruses already present in the EU. Strawberry crinivirus 3,
strawberry crinivirus 4 and strawberry polerovirus 1 meet all criteria for being considered as potential
Union QPs, except for the impact in the EU territory, on which the Panel was unable to conclude. Fragaria
chiloensis cryptic virus, Fragaria chiloensis latent virus and strawberry pseudo mild yellow edge virus do
not meet the criterion of having potential negative impact in the EU. For several viruses, especially those
recently discovered, the categorisation is associated with high uncertainties mainly because of the
absence of data on their biology, distribution and impact. Since this opinion addresses specifically the
non-EU viruses, in general, these viruses do not meet the criteria assessed by EFSA to qualify as potential
Union regulated non-quarantine pests. [-]
