EuroBlight, the international consortium tracking the spatial distribution of Phytophthora infestans, the pathogen responsible for late blight in potato crops, has published the results of its extensive 2019 survey work, revealing the distribution and diversity of dominant clones in the crop.
EuroBlight’s extensive team of disease ‘scouts’ collected around 1,800 samples during the 2019 season, pressing disease lesions on to special cards which then underwent DNA fingerprinting in the labs at the James Hutton Institute in Scotland and INRAE in France. The DNA data was then used to define the clonal lineages of the pathogen and combined with geolocation data to plot the diversity across Europe, reports the James Hutton Institute website.
EuroBlight’s key findings:
