It isn't hard to find Fusarium Head Blight (FHB) or Bacterial Leaf Streak (BLS) across much of Minnesota.
BLS is appearing relatively late in the grainfill period, and yield losses caused by the disease will be relatively small.
The same cannot be said for FHB, as the conditions continue to favor disease development. The best time to assess how many early infections occurred is probably this week. These early infections result in the characteristic tumbstone kernels.
