Rapid Pest Risk Analysis (PRA) for: Iris Yellow Spot Virus
This rapid PRA is an update of a 2007 UK PRA which concluded Iris Yellow Spot Virus (IYSV) posed a risk to seed and bulb crops of edible Allium species in the UK. This PRA shows IYSV is an economically important pathogen of Allium crops in some regions, though it has a much wider host range and in Europe its impacts have been small. Spread is primarily by onion thrips (Thrips tabaci), its global range has increased significantly in recent years and the prospects of continued exclusion from the UK are very poor.
