NW TX Panhandle | Also had what appears in your photos in the TX Panhandle this year. It's a virus. Not sure exactly which one, but to one degree or another they're all related. Most likely its' what we call High Plains Virus but I didn't send in any to a lab for confirmation as the prognosis is the same for all (BYD virus, typically has some red/purple hue along with yellowing of the leaf, whereas this doesn't). No treatment available for a virus. It's not stripe rust. A 10x lens will show that there are no rust pustules on the leaves. Had a lot of folks spraying fungicide thinking it was rust but it wasn't. Although some rust did appear later in our season. We're about 2 weeks from HRW wheat harvest.
