Following a request from the European Commission, the EFSA Panel on Plant Health performed a pest
categorisation of
Guignardia laricina
, a well-de
fi
ned and distinguishable fungal species of the family
Phyllostictaceae. The pathogen is regulated in Council Directive 2000/29/EC (Annex IAI) as a harmful
organism whose introduction into the EU is banned.
G. laricina
is native to East Asia and causes a
shoot blight disease of
Larix
spp. Major hosts of
G. laricina
are European larch (
Larix decidua
) and two
North American larch species (
Larix laricina
(tamarack) and
Larix occidentalis
(Western larch)).
Larix kaempferi
(Japanese larch) is reported as susceptible. The only other host in nature is Douglas
fi
r
(
Pseudotsuga menziesii)
, which is reported as an incidental host, but various other conifers have been
reported as susceptible following arti
fi
cial inoculation, including
Picea abies
. The fungus is not known
to occur in the EU but could enter via plants for planting (including arti
fi
cially dwarfed plants) and cut
branches of
Larix
spp. It could establish in the EU, as hosts are present and climatic conditions are
favourable. The pathogen would be able to spread following establishment by natural dissemination of
ascospores and pycnospores and by human movement of infected plants for planting. Should the
pathogen be introduced in the EU, impacts can be expected in larch forests, plantations and nurseries,
leading to reduced tree growth and ecosystem service provision. The key uncertainties concern the
current distribution and level of impacts in the native range of the pathogen. The criteria assessed by
the Panel for consideration as a potential quarantine pest are met. As the pest is not present in the
EU, not all criteria for consideration as a regulated non-quarantine pest are met. [-]
