A bacterium in the genus Xanthomonas, causing a foliar disease of corn known as bacterial leaf streak (BLS), has been found in corn fields throughout Nebraska and in additional neighboring states. Symptoms of the disease resemble other corn foliar diseases, including gray leaf spot and southern corn leaf blight. There is no evidence that the BLS pathogen is seed-borne or that it colonizes vascular tissues thus causing a vascular wilt. Where it occurs in South Africa, BLS has been associated with crop residue-borne inocula, overhead irrigation, and warm temperatures; impacts on yield usually have been minimal.
