Stripe rust continues to expand in Nebraska wheat fields, according to the latest wheat disease surveys conducted during wheat field days held June 9–12. These events were hosted in Hitchcock, Perkins, Deuel, Cheyenne, Box Butte, and Banner counties and saw strong attendance from growers, crop consultants, students, industry professionals, and representatives from Nebraska Extension and other institutions.
Stripe rust was confirmed in nine new counties in the southwest and Panhandle regions, bringing the total affected counties in Nebraska to 14. So far, the observed levels remain mostly at trace amounts, but the spread highlights the importance of monitoring disease conditions closely during the growing season.

Leaf rust, on the other hand, remains much more limited in Nebraska wheat. It has only been confirmed in Lancaster County and also at a trace level. Experts continue to monitor the region for any additional signs of spread.

In addition to rusts, other wheat diseases were also observed during field visits. These included the wheat streak mosaic virus (WSMV) complex and fungal leaf spots like tan spot and Septoria. These diseases were present at low to moderate levels across surveyed fields.
The disease surveillance conducted during the Nebraska wheat field days plays a vital role in identifying threats early, sharing updates with the agricultural community, and supporting overall crop health through better disease management practices. Ongoing scouting and timely updates will help guide effective responses throughout the rest of the growing season.
