BLS in corn was first found in my county in SW Nebraska in 2014 and confirmed in 2016 and is still prevalent. Effect on yield is still not well defined. We have had some irrigated fields that will turn a white shirt red walking through scouting that still yielded pretty well. Some varieties are better but not a really bulletproof resistance that I have seen but I think it is persistent in the soil. My comments are anecdotal but UNL extension researcher Dr Tamora Jackson Ziems is probably the leading authority on it.
Thanks for information. You are sure right on what it looks like when a susceptible hybrid is loaded top to bottom with lesions. There has to be some yield impact with so much photosynthetic area lost in the upper canopy. We have some side by sides from the field in the video. Should get some data on susceptible vs more tolerant. | 
Bacterial Leaf Streak could be the disease causing more yield loss this year!
