The powdery mildew citizen science scheme was launched in mid-May. Since then samples have been received from as far north as Moray, Scotland, to the south coast around Portsmouth. Such a range shows, on a small scale the great abundance of powdery mildews, and will help to gain a truly representative overview of the pathogen in the UK.
After morphological analysis the potential powdery mildew species have been narrowed down with the results below.

Extraction of the fungal DNA has begun and we are close to gaining sequence data for these species. This data will then allow for comparison with a vast library of other such DNA sequences and an accurate identification to be made.
