Goss’s wilt is a disease of corn caused by the Gram positive bacterium Clavibacter michiganensis subsp. nebraskensis (Cmn). The disease was first identified in Nebraska in Dawson County in 1969 (Clafin, 1999). Over the next decade, the disease was reported in 53 Nebraska counties and five of the six bordering states where it resulted in substantial (40 to 60 %) yield loss. Corn breeders successfully identified genetic resistance in field corn, and thereafter the disease occurred sporadically and rarely caused yield loss.
