Get a Head Start Against Head Scab in 2023

December 16, 2022
Fusarium head blight on wheat

Fusarium head blight, also known as head scab, is currently the most economically important wheat disease in the U.S. While damage from this disease can vary widely each year, it can cause significant yield losses and reduced grain quality.

Fusarium head scab symptoms are typically confined to the head and grain. The first noticeable symptom tends to be bleaching of some of the spikelets, and when examined closely, pink to orange spores may be visible on infected plants.

As you make your disease management plans for 2023, keep these tips top of mind:

  • Plan before planting. If you practice tillage, be sure to bury residue after growing small grains or corn to help reduce the potential of infecting wheat in the following season. If possible, rotate crops away from small grains and corn. You can also choose wheat varieties with some level of head scab resistance.
  • Assess head scab risk. Specialists with the University of Tennessee Extension recommend using the U.S. Wheat & Barley Scab Initiative’s Fusarium Risk Tool for updates about head scab risk. Warm, wet weather and high humidity during the flowering and early grain formation stages help head scab thrive. If conditions are right for head scab development or your fields have a history of head scab, consider applying a preventive fungicide to protect your wheat.
  • Choose a fungicide with a flexible application window. Weather delays and varying growth rates across the field can throw a wrench in your application plans. By using a fungicide with a flexible application window, like Miravis® Ace, you can take the stress out of controlling head scab and protect both the main wheat heads and tillers for maximized yield potential.

Watch as Syngenta Agronomy Service Representative Dan Maxfield walks through a wheat trial focused on protecting against head scab at the Ephrata, WA, Grow More™ Experience site:

Consider Miravis Ace fungicide, applied at 13.7 fl oz/A, to get a head start on head scab in 2023. Allowing applications as early as 50% head emergence up to flowering, Miravis Ace gives you more freedom to spray on time and get effective disease control in your fields.
