EPPO Reporting Service (2007/176) : present, reported again in 2006 after 40 years of absence, one outbreak in Peloponnese on solanaceous crops, under official control.

NPPO (2021): during the annual survey programme samples of potato tubers originated from the Municipality of Leukogeia (region of Drama) was found infected by Ralstonia solanacearum (pathotype II). The infested area covers a field of around 0.7 ha where ware potato is cultivated. Official phytosanitary measures were adopted for the eradication of the pest according to presidential Degree 255/2000 and Directive 93/85/EC as amended.
