First report of Curtobacterium flaccumfaciens pv. flaccumfaciens in the Netherlands
Curtobacterium flaccumfaciens pv. flaccumfaciens (EPPO A2 List) causing vascular wilt of bean is reported for the first time from the Netherlands. The pathogen was detected in September 2024 from green beans (Phaseolus vulgaris) grown in three fields belonging to the same operator in the municipality of Altena. No specific symptoms were observed. These findings were detected following tracing of seed lots originating in the USA. The seed lot originally imported from the USA had been marketed as sub-lots to several operators in the Netherlands and other EU Member States. Eradication measures are being taken. They include the destruction of the entire crop (including roots) and crop remains; hygiene measures for machinery, root/tuber crops, and personnel for the next two years; a fallow period of at least 120 days; prohibition to cultivate Fabaceae for the next two years; and the eradication of any weeds and volunteer seedlings of Fabaceae.
A buffer zone (100 m radius around the infested field) has been established where growers were advised not to cultivate Fabaceae for the next two years. In addition, monitoring surveys will be carried out in demarcated fields (infested fields plus buffer zones) for the next two years, including sampling and testing of any Fabaceae present.
The pest status of Curtobacterium flaccumfaciens pv. flaccumfaciens in the Netherlands is officially declared as: Present: under eradication.
