Last week the Plant Disease Clinic received the first sample of the year with symptoms typical of barley yellow dwarf virus. This disease can be seen on oats and wheat every year, and it is one of the major disease problems on oats in the state. This year yellow dwarf symptoms will probably be less severe than normal on oats because of the early planting that occurred.
