Following a request from the European Commission, the EFSA Panel on Plant Health (PLH) performed
a pest categorisation of
Mycodiella laricis-leptolepidis
, a well-de
fi
ned and distinguishable fungal species
of the family Mycosphaerellaceae. The former species name
Mycosphaerella laricis-leptolepis
is used in
the Council Directive 2000/29/EC. The pathogen is regulated in Annex IAI as a harmful organism
whose introduction into the EU is banned.
M. laricis-leptolepidis
is native to East Asia and causes a
disease known as needle cast of Japanese larch (
Larix kaempferi = Larix leptolepis
) and Kurile larch
(
Larix gmelinii
). European larch (
Larix decidua
) was found to be susceptible to the disease as
introduced tree in Japan. The fungus could enter the EU via plants for planting 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 human movement of infected plants for
planting and by dissemination of ascospores. Should the pathogen be introduced in the EU, impacts
can be expected due to needle loss in larch forests and plantations, thus leading to reduced tree
growth and ecosystem service provision. The use of resistant/tolerant varieties can reduce the impacts.
The key uncertainties are the knowledge gaps concerning (i) the potential range of spread through
ascospores and (ii) the 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. For regulated non-quarantine pests,
the criterion on the pest presence in the EU is not met. [-]
