Winter wheat in Wisconsin is moving through growth stages very rapidly over the past week due to ample moisture and heat. I have visited several fields this week with heads emerging or almost completely emerged. Anthesis (flowering) will begin in many winter wheat fields this week, if it hasn’t already started. With the start of anthesis comes the critical time to consider a fungicide application for Fusarium head blight (FHB or scab).
