Interpretive Summary: Managing the introduction of invasive pest species requires knowledge of the current geographic distributions of pathogens. Bacterial stripe of pearl millet, caused by Acidovorax avenae subsp. avenae was observed in the southeastern United States in 1999 and 2001. The disease has previously been known to occur only in Nigeria. When pathogenicity was compared, bacteria isolated from pearl millet differed from those isolated from corn indicating that the disease was not the result of spread of the corn pathogen to a new host. The bacterium was determined to be seed-borne in pearl millet, indicating the need to assess seed-production practices to minimize inoculum levels in and pathogen dissemination by seed.
