In 1995–09, The Netherlands were confronted with an outbreak of brown rot in potato ( Ralstonia solanacearum race 3). An intensive eradication programme was started. The strategy employed consisted of two components: (1) complete elimination of brown rot in the potato‐production column, and (2) prevention of new introductions in the production columns of Dutch host crops of R. solanacearum race 3, i.e. potato and tomato. With respect to the first component, all infected lots and all lots related to infected lots have been traced and eliminated. With respect to the second component, possible routes for new brown‐rot introductions into the production column have been identified and controlled. The greatest risk is associated with the use of infested surface water. In 1996, an extensive survey was carried out to investigate the spread of the bacterium in surface water in The Netherlands. The results suggest that the elimination strategy will be successful. After it has been established that the potato‐production system is free from brown rot, suitable monitoring and control programmes for the production columns of potato and tomato will be maintained to safeguard production.
