Under official control.
EPPO Reporting Service (1996/22) : 4 foci were observed in autumn 1995. Two were on tomato under glass, in Lot et Garonne and Loire-Atlantique, one on outdoor tomatoes in Lot et Garonne, one on a plot for comparative trials of potatoes in an experimental station in Essonne (far from any production areas for seed or ware potatoes). Under eradication.
EPPO Reporting Service (1997/111) : no further cases since 1995. Surveys of seed and ware potatoes in 1996 gave negative results in 7300 tests. In a survey of waterways and Solanum dulcamara in 1996, one plant gave a positive.
EPPO Reporting Service (2001/022) and 2001/042: found again in 2000-09 in seed potatoes grown by a grower in Haute-Normandie (from Dutch seed potatoes imported in 1998). Surveys conducted in all fields planted with seed potatoes produced by this grower (in the North of France). Eradication measures (according to EU Control Directive) taken wherever the disease found.
EPPO Reporting Service (2004/084) : outbreak on Pelargonium in Poitou-Charentes region in 2003. Eradicated.
In 2011, the NPPO declared the eradication of R. solanacearum.
EPPO Reporting Service (2014/071) : 1 outbreak was detected in 2013 in Marne department (Champagne-Ardenne region) on ware potatoes and farm saved seed potatoes, under eradication.
