Timing of Fungicides for Scab Control in Wheat and Barley

Scab in wheat

Some winter wheat is now approaching the growth stage that is most sensitive to scab infection. Also, the earliest planted spring wheat and barley fields are beginning to head out. Environmental conditions in the next few weeks will play a significant role in determining if scab will be problematic this year. The small grains disease forecasting model is an excellent resource in determining the risk for scab development. If conditions are conducive for scab development, recommended fungicides can be effective in reducing scab development, particularly if applied at the appropriate stage of development.
