Following a request from the European Commission, the EFSA Plant Health (PLH) Panel performed a
pest categorisation of
Bretziella fagacearum
, a well-de
fi
ned and distinguishable fungal species of the
family Ceratocystidaceae. The species was moved from the genus
Ceratocystis
to a new genus
Bretziella
following phylogenetic analysis of the species and its close relatives. The former species
name
Ceratocystis fagacearum
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.
B. fagacearum
is only
reported from the USA, where it causes a wilt disease on
Quercus
spp. Other hosts are reported based
on inoculation trials, although Chinese chestnut (
Castanea mollissima
) is reported to be naturally
infected. No North American oak species has been found to be immune to the disease. The European
oak species
Quercus robur
,
Quercus petraea
and
Quercus pubescens
were found to be susceptible in
inoculation experiments. The pest could enter the EU via wood (with and without bark, including wood
packaging material), plants for planting and cut branches. Hosts and favourable climatic conditions are
common in the EU, thus facilitating establishment. The pest would be able to spread following
establishment by means of root grafts, insect vectors and movement of wood, plants for planting and
other means. The pest introduction would have impacts in woodland and plantations, as oak wilt
disease is often lethal in a short period of time. Wood treatment (debarking, kiln drying, fumigation),
prompt removal of affected trees and creating root-free zones between affected and healthy stands
are available control measures. The main knowledge gaps concern (i) the survival of the fungus in
wood during transport and the association with propagation material, (ii) the presence of suitable
vectors in Europe and (iii) the relative susceptibility of the oak species native to Europe under natural
conditions. 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. [-]
