The Food and Environment Research Agency found the pathogen on Vaccinium on 14 and 24 February.
This follows further outbreaks of Phytophthora kernoviae discovered on bilbery by Fera earlier in the year.
The first cases appeared in Cornwall in 2003 at three nursery sites and public gardens, but in 2008 Defra confirmed the first discovery in the wild of P. kernoviae on bilberry. Cases have since been reported in Cornwall, Wales and Scotland.
