or growers intent on applying one fungicide application per year when flag leaf disease levels are low to moderate, Bayer recommends waiting and applying Folicur EW or Prosaro at head timing for best results. Applying at head timing will protect against various head diseases including fusarium head blight and leaf diseases while maximizing both quality and yield. On the right are three photos of a wheat head at various stages of development. Targeting the "optimal head" stage will most often deliver the best results. However, Bayer research indicates that slightly earlier or later will still provide a positive return on investment. Remember, an application at head timing can supply both flag leaf and head protection throughout the grain-fill period.
