× Likelihood For "Pest is Introduced" the lowest value of Entry or Establishment, as both are required for a successful introduction. For "Pest Spreads to Maximum Extent" this is an expert judgement on the likelihood of this occurrence. See Guidance Document for more Information Close Likelihood [1 - 5]				4
× Spread The rate at which a pest can expand, by natural dispersal only, within an area. See Guidance Document for more Information Close Spread [1 - 5]	1
× Impact The highest value from economic, environmental or social impacts. See Guidance Document for more Information Close Impact [1 - 5]		2
× Value at Risk The value of the hosts or industries at risk from this pest in the UK. See Guidance Document for more Information Close Value at Risk [1 - 5]		2

Action

Great Britain: Statutory action in line with current regulation, but proposed for deregulation. Northern Ireland: Statutory action in line with legislation.

General Comments

Virus affecting sour cherries, with other stone fruit not showing symptoms if infected. Present in mainland Europe and beyond, but not known to be in the UK. Evidence of impacts is limited.

Key uncertainty for pest

Whilst there are not large amounts of data on the virus, this may be due to a low level of impact. Key uncertainties include the level of impacts seen and the level of commercial production of sour cherry in the UK.
