    Abstract

    Potato blackleg caused by pectinolytic Pectobacterium atrosepticum (syn. Erwinia carotovora subsp. atroseptica), P. carotovorum subsp. carotovororum (syn. E. carotovora subsp. carotovora) and Dickeya spp. (syn. E. chrysanthemi) gives increasing damage in seed potato production in Europe. In the past, the blackleg pathogens contributed equally to the occurrence of blackleg, but in the last five years Dickeya spp. was responsible for 50-100% of the incidences in France and The Netherlands. In this paper, the diversity and some ecological aspects of Dickeya spp. are discussed, which may explain the increasing significance of this pathogen
