  1. Select variety with highest possible resistance (no varieties are completely resistant), see variety trial information or fact sheet below for variety ratings

  2. Manage residue and avoid planting into corn residue

  3. Monitor conditions and use fungicide as needed. Spray timing should be approximately 2 to 5 days after 50 percent of the heads have begun flowering, or 5 to 7 days after most heading (pictured). See the Wheat Fungicide Efficacy Chart for products registered for head scab management.
