If it’s not soaking rain one week, it’s a dry spell the next. You never know what to expect from Mother Nature during the growing season. Whether it’s too much rain or not enough, the risk of yield loss is real and can threaten yield potential at harvest.
The weather impact
When weather conditions are wet and humid, diseases like Fusarium head scab and leaf rust can spread fast. Left untreated, these fungal diseases can severely damage wheat crops and limit grain quality and yield. In dry conditions, drought pressure can slow the tiller and plant growth and reduce grain sizes, hurting your bottom line.
In wet or dry conditions, yield potential takes a hit, but choosing a fungicide with plant-health benefits can help crops stay resilient in the face of dry or wet weather.
Choosing the right fungicide
Your fungicide application shouldn’t just stop disease. Innovative products such as Syngenta’s Miravis® Ace fungicide can deliver disease control while also providing quantifiable yield-boosting plant-health benefits. It all comes down to three pillars of plant health:
- Light absorption: Greener leaves can capture more light energy from the sun and focus more energy on money-making yield.
- Water conservation: Better water conservation with plant-health fungicides means a lower transpiration rate in the leaves, minimized water vapor loss in the crops, better moisture retention and more efficient use of water, which is key in a drought.
- Harvest efficiency: With fungicides that control disease and help maximize plant health, standability and harvestability is preserved, making for more efficient harvests.
As weather patterns become more unpredictable, its important to protect your crop with a fungicide that supports wheat performance in a variety of conditions. No matter which extreme your field faces, one thing remains constant: stress limits yield. That’s why proactive protection is key and where Miravis Ace comes in.
How Miravis Ace helps:
- Best-in-class disease control powered by ADEPIDYN® technology, the most potent SDHI molecule available
- Longer residual activity for extended protection in wet or dry conditions
- Creates a reservoir within the wax layer of the leaf that withstands rain and degradation
- Delivers plant-health benefits for cleaner and greener crops

Wheat growers don’t get to choose the weather, but they can choose a fungicide that works in any condition. Miravis Ace can manage wet-weather disease threats and protect plants from dry-season stress, giving your wheat the best shot at a high-yield harvest.
