Barley also is fairly susceptible, and severe infect ions have been seen in North Dakota. Wheat streak was confirmed in some late planted oats this year, a first report of wheat streak in oats in North Dakota. Winter rye from areas adjacent to infected winter wheat has been tested at NDSU arid found negative for wheat streak. Other states have reported rye to be a possible host. Pros millet, sorghum and sorghum sudan are not reported to be affected by wheat streak.
Corn is a very important host for the mite and virus.
Mites move into nearby green corn as wheat matures, then mite moves out of corn into newly emerged winter wheat in the fall. Mite feeding causes kernel red streak in corn. P survey of corn fields in eastern North Dakota in August revealed high mite populations in green corn. Broad leaved crops such as mustard, flax arid sunflowers are immune to wheat streak mosaic. The mite overwinters or winter wheat arid a few perennial grasses such as Canadian wild rye and Canadian bluegrass.
