Six variants of Cercospora beticola were isolated from the territory of Slovakia. According to the cultural properties on potato glucose agar medium they could be characterized as: dark grey, dark grayish-green, ash-grey, deep grayish-green, light grayish-green and white grayish-green. Inoculation of susceptible and resistant sugar beet cultivars showed a correlation between pigmentation intensity and aggressiveness, with darker variants being more virulent and sporulating more heavily.
