A survey of wheat fields in southern west central Nebraska (Furnas and Harlan Counties) on May 19 found most fields to have little or no disease. Two fields had a high incidence of barley yellow dwarf.
Four videos illustrate the spread of wheat curl mites among neighboring wheat fields and the importance of controlling these mites to curtail the development of three key viruses of winter wheat in Nebraska.
For wheat growers, one aspect of being a good neighbor is controlling volunteer wheat after harvest to stop wheat curl mites from moving into the new crop of wheat and transmitting viruses, particularly wheat streak mosaic virus. Volunteer wheat should be controlled in time to provide a two-week break in the green bridge.
