Following a request from the European Commission, the EFSA Plant Health (PLH) Panel performed a
pest categorisation of
Anisogramma anomala
, a well-de
fi
ned and distinguishable fungal species of the
family Valsaceae. The pathogen is regulated in Annex IIAI of Council Directive 2000/29/EC as a
harmful organism whose introduction into the EU is banned on plants of
Corylus
L., intended for
planting, other than seeds, originating in Canada and the USA. The fungus is native to eastern North
America and causes eastern
fi
lbert blight on cultivated hazel,
Corylus avellana
, as well as on wild hazel
(
Corylus
spp.). In the 1960s, the disease spread on infected plant material to Oregon, where it then
threatened US hazelnut production in the Willamette Valley. The pest could enter the EU via plants for
planting. Hosts and favourable climatic conditions are common in the EU, thus facilitating
establishment. The pest would be able to spread following establishment through infected plants for
planting and ascospore dispersal.
A. anomala
leads to canopy and yield loss and can cause death of
Corylus
trees. Should the pathogen be introduced into the EU, impacts can be expected not just on
hazel as a crop and as an ornamental but also in coppices and woodlands, where
Corylus
species
provide an important habitat. In Oregon, scouting for cankers, therapeutic pruning and copious
fungicide applications are reported to be necessary (but costly measures) to continue hazelnut
production in the presence of the disease. Breeding for resistance led to the selection of resistant
cultivars. The main knowledge gaps concern (i) the role of deadwood and cut branches as potential
entry pathways and means of spread and (ii) the susceptibility of
C. avellana
cultivars and of
Corylus
spp. in the wild in the EU. 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. [-]
