Early Season Scouting in Small Grains: Tan Spot
With the overcast and humid days which many parts of the state have been experiencing in the last week, be sure to scout smalls grains for signs of early tan spot infection. Tan spot will be particularly prevalent on previous wheat ground. Spring wheat in trials on the Northwest Research and Outreach Center at Crookston has 100% incidence with tan spot. There is some tan spot in the winter wheat. Early signs of tan spot in fields south of Moorhead, Minnesota, have also been identified.
