During the Crops and Soils Day in Crookston, University of Minnesota Small Grain Pathologist Ruth Dill-Macky said early symptoms of bacterial leaf streak include small water-soaked lesions extending along the leaf margins and midrib. “You will see some water droplets on the leaf in the early morning that may be milky in appearance because of the presence of this bacteria. Later on, they can dry to form a glaze on the leaf surface or sometimes they dry into small little granules that can appear anywhere between a whitey milky color all the way through to an amber.” As the disease develops, necrotic stripes can be found on the uppermost leaves. There is no immunity to the disease, but varieties are being developed with some level of resistance.
