1998 surveys on Clavibacter michiganensis subsp. sepedonicus and Ralstonia solanacearum in Slovakia
Surveys have been carried out in Slovakia on seed and ware potatoes harvested in 1998 for the presence of Clavibacter michiganensis subsp. sepedonicus and Ralstonia solanacearum (both EPPO A2 quarantine pests).
During these surveys, tests were performed according to relevant EU Directives on all multiplication fields of seed potatoes intended for seed or ware potato production (1241 samples), and on all seed potatoes which were subjected to national variety testing (108 samples). In addition, systematic checks were done on imported seed potatoes (202 samples) and random checks on imported ware potatoes (431 samples).
Results showed that in 1998 no infection by Clavibacter michiganensis subsp. sepedonicus or Ralstonia solanacearum was detected in seed or ware potatoes grown in Slovakia. Only one positive case of Clavibacter michiganensis subsp. sepedonicus was detected in a consignment of imported ware potatoes. This consignment was rejected at the border and not allowed to enter on the territory of Slovakia.
