According to Dr James Cooke at the James Hutton Institute in Scotland, having experienced one of the driest seasons since the Fight Against Blight began – clearly the weather has had a major impact. “After some early appearances on discard piles in Kent in mid-April, we have received very few recorded outbreaks compared to previous years.
This has allowed us the time to genotype the samples as they arrived in the lab, and we now have genotype data for 24 positive outbreaks.” The data indicates a similar pattern to last year with the new lineages 37_A2 and 36_A2 in Kent and, more recently, in Shropshire. There have been no findings of these genotypes beyond their 2017 range but the hot, dry weather will have been a major factor in limiting pathogen movement.
There are only two confirmed outbreaks from Lincolnshire, to date, so there remains a possibility that it is present but not yet sampled. Read full update on the AHDB Potatoes website
