When it comes to head scab, the true cost often isn’t fully realized in the field.
Beyond yield loss, grain quality issues and mycotoxin-related discounts can often reduce the value of an otherwise strong crop. Understanding the economics behind head scab control is key to protecting both yield potential and profitability.
Why head scab Is more than a disease issue
Fusarium head scab, also known as head blight, is one of the most economically damaging wheat diseases, with potential yield losses of up to 80%. Infection typically occurs from flowering (Feekes 10.5.1) through the early dough stage (Feekes 11.2) when warm, wet conditions can create outbreaks. Fields infected with head scab may experience:
- Reduced kernel size and test weight
- Lower overall grain quality
- Elevated levels of Deoxynivalenol (DON), a mycotoxin that can lead to rejected loads at the elevator
Even moderate scab pressure can significantly impact ROI, making disease management an important financial consideration — not just an agronomic one.
The real cost of DON
Yield loss is one of the most common impacts of head scab, but mycotoxin-related discounts can be just as costly. Grain that exceeds acceptable DON thresholds may face price reductions or limited marketing options, cutting into profitability after the crop is already in the bin.
For growers, that means:
- Fewer marketing opportunities
- Lower value per bushel
- Once DON levels are elevated, there are limited tools available to correct the issue. That’s why proactive management plays such a critical role in protecting grain quality.
Why timing matters for ROI
Effective head scab management hinges on a fungicide application that is made during early flowering to target the crop when it is most vulnerable to infection.
Missing the optimal timing — or using less effective Fusarium fungicides — can leave portions of the crop unprotected during peak infection periods. The potential result is increased disease pressure, higher DON risk and a reduced return on investment.
Choosing a fungicide that delivers consistent performance across variable conditions can help reduce that risk and protect more of the crop’s yield and quality potential.
Investing in protection that helps pay off
From an economic standpoint, investing in products that help preserve yield while also supporting grain quality can deliver value beyond the field.
Miravis® Ace wheat fungicide delivers disease control and plant-health benefits to help maximize yield and ROI potential. Because of its long-lasting head scab control, Miravis Ace protects both the main head and the secondary tillers. In addition to managing head scab, it helps keep plants healthier and reduces the risk of DON-related discounts at harvest.
