General Comments

Bacterium affecting hazel trees causing cankers and wilting of its host and causing significant commercial losses where it is present. The disease is only reported from Italy and Greece and is absent from the UK. Following assessment this pest does not meet criteria for an RNQP in GB due to its absence, but is recommended for regulation as a quarantine pest. A PRA will help to better establish the risk to the UK.
