Fusarium Head Blight (Scab) Forecasting Models

The recent windy days and reduction in extended moisture events has reduced scab risk based on the forecasting models. However, if frequent moisture events and high relative humidity occur, scab risk will increase quickly.  

In addition, the Minnesota models have the option of selecting forecasts based on variety ratings for resistance or susceptibility to scab. 

  • moderately resistant
  • moderately susceptible
  • susceptible
  • very susceptible

Select the rating for the variety grown to generate the risk map for the selected genetics.
