Bacterial leaf streak, caused by Xanthomonas vasicola pv. Vasculorum, was recently identified in Iowa. The disease has been found in field corn, seed corn, popcorn and sweet corn. Based on what we know about other bacterial diseases, the pathogen that causes bacterial leaf streak likely survives in corn residue and is spread by wind and rain/irrigation. The impacts on corn yield production are yet to be determined.
