Changes of late blight attack in conventional fields in the Nordic countries

Summary in the original language of the document

In Finland changes in the incidence and onset of potato late- blight epidemics were investigated and compared to possible changes in climate, presence of soil-borne inoculum, and aggressiveness of the blight population.
In Sweden, Norway and Denmark late-blight occurs every year in potato crops, although the time of onset and the severity of the epidemic vary from one year to the next.
