Head Scab Risk is high north of the Albemarle Sound and in Dare & Carteret counties and remains moderate in parts of the Piedmont. Rain in the coming week suggests risk will be high in most of the state. Wheat is likely near or at flowering in much of the northern Tidewater, and in the Piedmont. Wheat in Southeast NC is likely past the danger point. Apply a fungicide for head scab in the next 10 days if your wheat is currently between start of heading and full flower. (If a spray at the best timing of mid-flower is not possible, research shows that applications up to 5 to 6 days later can still be beneficial for head scab reduction.)

The most effective fungicides against head scab are Prosaro, Caramba, and Proline. Do not apply a strobilurin or a strobilurin-triazole mix.
