Following a request from the European Commission, the EFSA Panel on Plant Health performed a pest
categorisation of Chrysomyxa arctostaphyli, a well-defined and distinguishable fungal species of the
family Coleosporiaceae. The pathogen is regulated in Council Directive 2000/29/EC (Annex IAI) as a
harmful organism whose introduction into the EU is banned. C. arctostaphyli is native to North America
and is the causal agent of spruce broom rust. C. arctostaphyli is a heteroecious rust with a 2-year life
cycle alternating between the aecial host Picea spp. and the telial host Arctostaphylos spp. The main
reported aecial host is P. engelmannii, but also P. abies, P. pungens, P. sitchensis, P. glauca, P. mariana
and P. rubens (as well as Picea as a genus) are reported as hosts. The fungus is not known to occur in
the EU but could enter via host plants for planting and cut branches. It could establish in the EU, as hosts
are present and climatic conditions are favourable. The extent of overlap between the ranges of the telial
and aecial hosts is greater in the EU than in North America. The pathogen would be able to spread
following establishment by dissemination of spores and human movement of infected host plants. Should
the pathogen be introduced in the EU, impacts can be expected in spruce woodland, plantations and on
ornamental spruce trees, leading to reduced tree growth and associated ecosystem service provision.
The main uncertainty concerns the level of susceptibility of P. abies and P. sitchensis under European
conditions. The criteria assessed by the Panel for consideration as a potential quarantine pest are met.
As the pest is not present in the EU, not all criteria for consideration as a regulated non-quarantine pest
are met [-]
