Comments
Up till 2003, there were no recent records (e.g. in 1992 all results from annual surveys of UK seed and ware crops were negative).

EPPO Reporting Service (2003/159) , EPPO Reporting Service (2004/089) : ring rot was found in 2003-11 in seed potatoes at one farm in Wales. Intensive tests found no related infestations. Outbreak now considered to be contained, under official control.

Official surveys carried out in the UK did not detect ring rot in the 2008 potato crops. This outbreak is now considered eradicated (Giltrap, 2009).

Not detected during official surveys carried out on UK ware and seed potato crops of 2009, 2011.
