The combination of infection timing and non-uniform crop development makes head scab control exceptionally challenging. Plus, protecting yield potential and grain quality usually means choosing to protect the main heads that have flowered, leaving secondary tillers at risk. However, those secondary tillers can play a primary role in increasing your potential yield and ROI.
As you begin making your disease management plan, keep these tips in mind:
Plan ahead to protect yield potential. 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 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 longer-lasting disease control. Choosing a fungicide like Miravis® Ace can make a tremendous difference on your yield monitor. Powered by the most potent SDHI available, ADEPIDYN® technology, Miravis Ace helps protect the main heads and tillers long after you spray for better potential yield and grain quality.
