Surveys on potato bacteria in Slovakia: harvest 2001

For the last 5 years, systematic surveys on Clavibacter michiganensis subsp. sepedonicus and Ralstonia solanacearum (both EPPO A2 quarantine pests) have been carried out in Slovakia. Field/store inspections and laboratory testing were performed on the 2001potato harvest. Detection methods were used in accordance with EU Directives 93/85/EEC and 98/57/EC. During this survey, the following numbers of samples were tested:
- 454 samples of domestic seed potatoes (corresponding to the whole Slovak production, i.e. 2.565,5 ha)
- 61 samples of domestic ware potatoes (corresponding to 8.5 % of total production, i.e. 722 ha)
- 184 samples of imported seed potatoes
- 51 samples of imported ware potatoes (out of these, 37 were only tested for ringrot)
- 122 samples taken from national cultivar testing trials
No positive result was obtained for domestic potato production nor for imported potatoes in 2001. The situation of both C. michiganensis subsp. sepedonicus and R. solanacearum in Slovakia can be described as follows: Absent: confirmed by survey.
