Stripe rust and leaf rust were observed in Nebraska fields this week; however, these diseases are not expected to cause significant yield reductions due to their late arrival in the wheat growing season.
Tan spot was identified in several fields recently surveyed in the Panhandle, and though Fusarium head blight hasn't been observed in fields yet, parts of western Nebraska are currently at high risk for infection.
This week high levels of stripe rust and leaf rust were observed in wheat plots at the Eastern Nebraska Research and Extension Center (ENREC) near Mead, Sauders County, and at Havelock Farm in Lincoln, Lancaster County.
The wheat crop condition was good to excellent in the majority of fields surveyed this week in south central and southwest Nebraska. Stripe rust has been confirmed in 15 counties; leaf rust has been confirmed in one county.
