Stolbur phytoplasma is an important pathogen associated with the Bois noir (BN) disease of grapevines. In the Moravia wine region, plants exhibiting BN-symptoms were observed in 14 localities, covering all four of the wine sub-regions. On other hand in the Bohemia wine region, symptomatic plants occurrence was only sporadic. All of the stolbur phytoplasma isolates were ascribable to the 16SrXII-A subgroup and the tuf-b type. The loss of grape clusters reached 50%, comparing the fully affected grapevine plants with the healthy ones.Keywords:
