• Pest is introduced with vector or finds vector

• Plants for planting (with soil)

• Natural spread
• insect vectors

× 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]		2
× 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]			3
× Impact The highest value from economic, environmental or social impacts. See Guidance Document for more Information Close Impact [1 - 5]				4
× 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]					5
× Likelihood x Impact The likelihood multiplied by the impact, which shows the risk to the sector. See Guidance Document for more Information Close Likelihood x Impact [1 - 25]	8
× UK Relative Risk Rating Likelihood x Impact x Value at Risk. See Guidance Document for more Information Close UK Relative Risk Rating [1 - 125]	40

General Comments

Bacterium which causes Syndrome des Basses Richesses in sugar beet and has also been found in potato. Often co-occurring with ‘Candidatus Phytoplasma solani’ and associated with planthopper vectors, one of which is present in the UK. Main potential pathway is spread of diseased vectors from parts of the EU where the bacterium is present. Sugar beet and potato growers may wish to monitor for presence of the main vector.
