Bacterial wilt of dry beans, caused by Curtobacterium flaccufaciens pv. flaccumfaciens (Cff), has historically posed sporadic but often serious production problems in dry beans throughout the irrigated High Plains since its first report from South Dakota in 1922. In the early 1980s, the disease mysteriously disappeared, appearing only periodically on cull seeds at the processing plants, but with little economic damage.
