First two pictures below shows a virus disease, likely Barley Yellow Dwarf. The straight line below is a variety difference.

Virus’ are vectored by aphids typically in the fall. Bird Cherry Oat aphids are grass feeders and carry the virus in their saliva as they suck out plant juice.

Including insecticide on wheat seed helps to prevent the disease. By a wide margin, ROI for insecticide is best on wheat followed by corn and is costly replant insurance on beans.

Yield loss is commonly 50% and higher depending on when the disease sets in. Nothing can be done now to help.

Below shows some septoria starting in the lower canopy. Wet and cool this week will increase incidence. Thicker canopy, more risk. Any of the Strob based fungicides provide good control of early season diseases.

Late planted wheat has improved but still looks rougher than I like. Very consistent across my area. Early planted wheat has improved much over the last few weeks. Seeing some sulfur deficiencies showing up as well.
