General Comments

Fungal pathogen widespread in parts of Europe and Asia which can affect tree vigour and timber production for a number of conifer species, including those commonly grown for forestry purposes in the UK. Not known to be present in the UK, but there is a small risk of introduction particularly through imports of conifer poles and stakes.
