The Panel on Plant Health performed a pest categorisation of Phyllosticta solitaria, the causal agent of
blotch of apple, for the EU. The pest is a well-defined fungal species and methods are available for its
detection and identification. P. solitaria is present in Canada and the continental states of the USA. The
pest is not known to occur in the EU and is listed in Annex IAI of Directive 2000/29/EC, meaning its
introduction into the EU is prohibited. The major cultivated host is Malus domestica (apple), but wild
Malus and Crataegus species may also be affected. All hosts and major pathways of entry of the pest
into the EU are currently regulated. The disease is favoured by warm, wet weather during the growing
season. Host availability and climate matching suggest that P. solitaria could establish in parts of the
EU and further spread mainly by human-assisted means. The pest causes premature defoliation, fruit
cracking and rot, and twig and branch cankers. At the beginning of the 20th century, disease
incidences of 70–90% on fruit of untreated susceptible apple cultivars had been reported and the
disease was considered as a limiting factor in the commercial production of those cultivars. Nowadays,
the disease is rare in commercial apple orchards, probably due to regular fungicide sprays against
other diseases. The pest introduction in the EU would potentially cause impacts to apple production.
The main uncertainties concern the host range, the maximum distance of conidial dispersal by winddriven rain, and the magnitude of potential impacts to the EU. P. solitaria meets all the criteria
assessed by EFSA for consideration as a potential Union quarantine pest. The criteria for considering
P. solitaria as a potential Union regulated non-quarantine pest are not met, since the pest is not known
to occur in the EU. [-]
