Wheat is starting to flower in southern Indiana. Recent weather has continued to favor a forecast of high risk potential of infection for most of the state. It is time to consider your spray options for wheat if Fusarium head blight is a concern. The best time to make a fungicide application is when 50% of heads are starting to flower – watch for anthers (flowers) emerging from the wheat heads to make this determination. The best control, with all fungicides, will occur when applications are made at this time. Caramba and Prosaro (FRAC group 3) or Miravis Ace (FRAC group 3 + 7) give good control of scab as well as most leaf and head diseases."
