Clavibacter michiganensis subsp. sepedonicus occurs in Crete (GR)

Clavibacter michiganensis subsp. sepedonicus (EPPO A2 quarantine pest) was detected for the first time in 1997 in the Lasithi plateau in Crete (GR). The bacterium was isolated from infected potato tubers (Solanum tuberosum cvs. Spunta and Kennebec) showing visible symptoms, and the identity of the bacterium was confirmed according to EU Directive 93/85/EEC. In 1997 and 1998, a survey confirmed the presence and the distribution of the bacterium in the Lasithi and Heraklion provinces. In 1998, the bacterium was detected in 99 out of 459 tested samples (21%) from Lasithi plateau, and in 18 out of 155 samples (6%) from different fields in Heraklion province. The EPPO Secretariat had previously no data on the presence of ring rot in Crete, and will enquire on the present status of the disease in Greece.
