National control measures for Clavibacter michiganensis subsp. sepedonicus1

Clavibacter michiganensis subsp. sepedonicus has a clearly restricted geographical distribution in the EPPO region, being present almost exclusively in the north and east. Countries where it is absent take strong phytosanitary measures to prevent its introduction. Within the European Union, countries where it is present aim to eradicate the disease. The EU Control Directive for ring rot puts in place community-wide measures for surveillance, containment and eradication.
