Clavibacter michiganensis subsp. sepedonicus found on imported potato lots

In 1997, the French Plant Protection Service intercepted four imported seed potato consignments from Germany which were infected by Clavibacter michiganensis subsp. sepedonicus (EPPO A2 quarantine pest – see EPPO RS 98/054). Two lots were sent back to Germany but due to the delay between sampling and results of the analysis, two other lots were planted in the field. Eradication measures have been taken and concerned 39 ha (corresponding to 14 growers). The contaminated plants were lifted or destroyed, farm equipment was disinfected and surveys will be carried out in the infected fields.
