Wheat in southeastern and south-central Kansas is at heading stages of development. Wheat in these areas will reach the growth stages critical for Fusarium in roughly week to 3-5 days. The model is indicating moderate or high risk of severe disease just as we head into the most vulnerable period of growth. The risk is likely to persist or increase if these regions continue to receive frequent rainfall and extended periods of high relative humidity. Growers in southeastern and south central Kansas should be monitoring situation carefully and planning to apply a fungicide if weather conditions remain favorable. Care should be taken to select an effective fungicide for management of FHB with Prosaro, Caramba and Miravis Ace being the best options. Many other fungicides are less effective or are not labeled for Fusarium suppression.
