First report of ‘Candidatus Liberibacter solanacearum’ on carrot crops in Estonia
During an official survey for ‘Candidatus Liberibacter solanacearum’ (potato haplotypes are listed in the EPPO A1 List) carried out in carrot (Daucus carota) production sites in Estonia, insects were caught with sticky traps and tested for the presence of the pathogen. The psyllid vector, Trioza apicalis, was found in 4 locations in the municipality of Saue. In September 2017, the presence of ‘Ca. L. solanacearum’ haplotype C was confirmed in 4 out of 7 samples of T. apicalis. No official phytosanitary measures will be taken. This is the first time that ‘Ca. L. solanacearum’ is reported from Estonia.
The pest status of ‘Candidatus Liberibacter solanacearum’ in Estonia is officially declared as: Present, only in some parts of the Member State concerned.
