• Pest is introduced

• Plants for planting (except seeds bulbs and tubers)

× 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]		2
× 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]				4
× 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]	4
× UK Relative Risk Rating Likelihood x Impact x Value at Risk. See Guidance Document for more Information Close UK Relative Risk Rating [1 - 125]	16

Action

Statutory action but not specifically regulated due to the mitigations provided by the vector listing (Thrips palmi)

General Comments

Virus found in limited parts of southern and eastern Asia, primarily affecting melons and watermelons. A watching brief will be maintained for any additional information about impacts on tomatoes or cucumbers. Mitigations against entry of the only known vector, Thrips palmi, also serve to mitigate against the entry of this virus.
