Abstract:
Following a request from the European Commission, the EFSA Panel on Plant Health prepared a list of
non-EU phytoplasmas of Cydonia Mill., Fragaria L., Malus Mill., Prunus L., Pyrus L., Ribes L., Rubus L.
and Vitis L. A systematic literature review and search of databases identified 27 phytoplasmas infecting
one or more of the host genera under consideration. These phytoplasmas were assigned to three
categories. The first group (a) consists of 10 non-EU phytoplasmas, known to occur only outside the
EU ('Candidatus Phytoplasma australiense', 'Ca. P. hispanicum', 'Ca. P. pruni'-related strain (NAGYIII),
'Ca. P. pyri'-related strain (PYLR) and Buckland valley grapevine yellows phytoplasma) or having only
limited presence in the EU ('Ca. P. aurantifolia'-related strains, 'Ca. P. fraxini', 'Ca. P. phoenicium', 'Ca. P.
trifolii' and 'Ca. P. ziziphi'). The second group (b) consists of three non-EU phytoplasmas, whose
presence in the target plant species is not fully supported by the available literature. The third group
(c) consists of 14 phytoplasmas with substantial presence in the EU (i.e. they are originally described
or reported from the EU or known to occur or be widespread in some EU Member States or frequently
reported in the EU). Phytoplasmas of categories (b) and (c) were excluded at this stage from further
categorisation efforts. One phytoplasma from category (a) ('Ca. P. phoenicium') was excluded from
further categorisation, as a pest risk assessment has been performed by EPPO. Comments provided by
the EU Member States were integrated in the opinion. The main uncertainties of this listing concern:
the geographic distribution and prevalence, the taxonomy, biology and host range. The phytoplasmas
considered as non-EU and whose presence in target plant species is fully supported by literature
(category (a)) are categorised by the Panel in a separate opinion.
