New report of Curtobacterium flaccumfaciens pv. flaccumfaciens in Spain
In Spain, Curtobacterium flaccumfaciens pv. flaccumfaciens (EPPO A2 List) was first reported in seeds in 2001 and later reported to cause bacterial wilt of beans (Phaseolus vulgaris) growing in fields in Andalucía in 2004 (EPPO RS 2006/120), before being eradicated in 2011.
In November 2025, 21 lots of beans (Phaseolus vulgaris cv. ‘Riñón’) were sampled from 12 fields from the municipalities of Pozuelo del Páramo and Roperuelos del Páramo (León province, autonomous community of Castilla y León). The bean lots came from a Protected Geographical Indication site and were intended for human consumption. In April 2026, the National Reference Laboratory identified C. flaccumfaciens pv. flaccumfaciens in a sample from one of the lots using molecular testing. Phytosanitary measures aiming at eradication have been applied according to Regulation (EU) 2016/2031: they include the destruction of the infested bean lot, and the prohibition to grow Fabaceae plants in the demarcated area (corresponding to the plots where the beans from the infected lot were cultivated). Further monitoring will be carried out in 2026 and 2027.
The pest status of Curtobacterium flaccumfaciens pv. flaccumfaciens in Spain is officially declared as: Transient, actionable, under eradication.
