New report of Clavibacter sepedonicus in Italy (Calabria)
The NPPO of Italy recently informed the EPPO Secretariat that Clavibacter sepedonicus (EPPO A2 List) was found in March 2026 in ware potatoes (Solanum tuberosum) from warehouses in Spezzano and Celio municipalities (Cosenza province, Calabria region). During official surveys, twenty samples of 200 asymptomatic tubers were tested for the bacterium. C. sepedonicus was identified in two of these samples by molecular testing. Phytosanitary measures have been applied with the aim of eradication, including destruction of all potatoes from the warehouses and disinfection of machinery and storage facilities where the infected tubers were found.
The pest status of Clavibacter sepedonicus in Italy is officially declared as: Present.
