Potential high risk to wheat crops but unlikely to come direct to the UK. Continue to monitor spread in countries of higher risk. Suggest PRA done at EU level.

General Comments

A pest representing a potentially high risk to a major UK crop (wheat). However the pathway for entry is unlikely to be direct into the UK and currently industry practice and legislation, in combination, appear to effectively mitigate risk.
