Dwarf bunt resistant lines in nurseries are not showing these symptoms. Fertility problems such as nitrogen deficiency are being seen due to high precipitation and cold temperatures. In the northwest part of the state, dwarf bunt is a severe problem, and the white winter wheats have been severely affected by snow mold. However, this is a small portion of the state acreage, though the area has a high yield potential. Barley yellow streak virus is a recurring problem in some areas.
Plants appear gray early on.
The vector dissipates after an inch of rain, but plants remain stunted. The virus passes through the eggs of the brown wheat mite. Symptoms are similar to wheat streak mosaic. Often, just half of the leaf will show symptoms. The driving factor seems to be continuous barley.
