Bacterial leaf streak (Xanthomonas vasicola vasculorum)
Iowa State University Extension Plant Pathologists have identified and confirmed several different cases of bacterial leaf streak in corn this growing season. Bacterial leaf streak is relatively new to the United States, with the first case identified in 2016, though symptoms of the disease have been present in Nebraska since 2014. In this video Ed Zaworski, plant pathologist at Iowa State University, takes you into the Plant and Insect Diagnostic Clinic as he examines a sample of bacterial leaf streak in corn.
