Following a request from the European Commission, the EFSA Plant Health Panel performed a pest
categorisation of
Sphaerulina musiva
, a well-de
fi
ned and distinguishable fungal species of the family
Mycosphaerellaceae. Following a recent phylogenetic analysis of the genus
Septoria
and other closely
related genera, a new name (
S. musiva
) was introduced for the species. The former species name
Mycosphaerella populorum
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.
S. musiva
is reported from
North and South America and not known to occur in the EU.
S. musiva
causes Septoria leaf spots and
cankers of poplar (
Populus
spp.). Of the poplars native to Europe,
Populus nigra
is reported as
susceptible and
Populus tremula
as susceptible when planted in North America. The hybrid
Populus x
canadensis
(arising from a cross of
P. nigra
and the North American
Populus deltoides
), widely grown
in the EU, is also susceptible. The pest could enter the EU on plants for planting, cut branches,
isolated bark and wood with and without bark.
S. musiva
could establish in the EU, as hosts are
common and favourable climatic conditions are widespread, and could spread following establishment
by natural dispersal and movement of infected plants for planting, cut branches, isolated bark and
wood with or without bark. The pest introduction would have impacts in woodlands, plantations and
nurseries. The pathogen is considered the most serious disease affecting hybrid poplar production in
North America. Selection, breeding and planting of resistant species and clones are the main methods
used to control the damage caused by the pathogen. There is some uncertainty on the geographical
distribution of the pest in the Caucasus, the Crimean Peninsula and South America and on the level of
susceptibility among
Populus
species native to Europe as well as
Salix
spp. 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. [-]
