August 2008


Bacterial wilt of dry beans, caused by Curtobacterium flaccumfaciens pv. flaccumfaciens (Cff), has long been a sporadic but often serious production problem throughout the irrigated High Plains. Because of the systemic nature of this disease, the pathogen will often color or stain seeds. This paper represents the first report of a new color variant for Cff and, combined with the occurrence of the other three pathogen variants for more than 50 years.
