Surveys on potato cyst nematodes in Slovakia
In Slovakia, surveys on potato cyst nematodes (Globodera rostochiensis and G. pallida, both EPPO A2 quarantine pest) have been carried out since 1993. Over the period 1993 to 2001, 16,375 soil samples have been collected, and the identity of the nematode was established using morphological characters and ELISA test. Results showed that G. rostochiensis was found in 1928 samples taken from small plots (;1 ha) and in 37 samples taken from large-scale production fields (;1 ha). In all cases, only G. rostochiensis was found, G. pallida was never identified. In all plots where G. rostochiensis was found, phytosanitary measures were taken to prevent any further spread and eliminate the nematode populations. The situation of G. rostochiensis in Slovakia can be described as follows: Present, only in some areas, subject to official control. The situation of G. pallida in Slovakia can be described as follows: Absent, confirmed by surveys.
