Clavibacter michiganensis subsp. sepedonicus found in Turkey

During the 2007 survey on seed potatoes in Turkey, 336 tuber samples from the Kayseri province (Central Anatolian region) were tested for the presence of ring rot (Clavibacter michiganensis subsp. sepedonicus) and brown rot (Ralstonia solanacearum – both EPPO A2 List). As a result, 3 samples were found to be infected by C. michiganensis subsp. sepedonicus. It is recalled that during an intensive survey carried out in 1988-1989, potato-growing areas of Turkey were found free from ring rot. According to the authors, this is the first record of C. michiganensis subsp. sepedonicus in Turkey. Strict control measures have been taken in contaminated and potentially contaminated fields.
The situation of Clavibacter michiganensis subsp. sepedonicus in Turkey can be described as follows: Present, first detected in 2007 in a small number of potato samples collected from the Kayseri province (Central Anatolia), under official control.
