WI 72 Hour Fusarium Head Blight Forecast

The prevalence of powdery mildew coupled with impending wheat flowering and risk of head scab many growers are considering holding off their fungicide application to target both pathogens. Based on our 24 to 72 hour prediction for Fusarium head scab using the Fusarium Head Blight Risk Assessment Tool the risk of Fusarium head scab for flowering wheat is low (May 10). However based on my observations and consultant and agronomist phone calls today we are still 5 to 7 days away from flowering in southern WI. I will rerun the model Sunday evening with and updated forecast.
