A survey was undertaken in Scotland to monitor seed and ware tuber production in Scotland for the presence of Dickeya spp., in support of Scottish legislation introduced in 2010, which established a “nil” tolerance for Dickeya infections in seed crops. This survey was risk-based and targeted stocks which held the greatest risk of carrying or contracting the disease. This survey was carried out in conjunction with the annual tuber surveys for Clavibacter michiganensis ssp. sepedonicus (potato ring rot) and Ralstonia solanacearum (brown rot) to comply with EU Commission Directives 2006/56/EC and 2006/63/EC, which requires member states to survey their potato production for the presence of these bacterial quarantine pathogens. A total of 212 samples were tested. Dickeya spp was not detected in any of the samples. Read more
