Using a Fungicide to Protect Your Wheat Crop

If your wheat crop made it healthily to this point in the growing season, you’re probably thinking about what you can do now to protect your yield. A fungicide application may be the right choice for your operation.

How do fungicides support a healthy wheat crop?

Fungicides can bring a substantial benefit to your wheat crop by improving plant health, increasing stability and protecting yield. Fungicides do their best work in fighting the yield-limiting effects of diseases such as stripe rust, head scab and powdery mildew—all diseases that can wreak havoc on a crop. 

Three classes of fungicide

Preventative fungicides

These protect wheat from diseases before they are present in the field. These include fungicides with strobilurin as the primary active ingredient, such as Quadris® and Headline®

Curative fungicides

These stop the spread of disease after it has infected the plant. These include those with triazoles as the active ingredient, such as Tilt®, Caramba® and Folicur®.

Combination fungicides

These are a mix of both preventative and curative fungicides and can protect plants from disease, while stopping the spread of disease already in the plant. These include products such as TwinLine®, Quilt Xcel® and Stratego®.

When should you apply fungicide to wheat?

If you’re experiencing early-season disease pressure in your wheat, then you’ll want to apply fungicide early on. 

However, if you think you’ll only have one opportunity to apply fungicide to your crop, applying at flag leaf emergence will help you achieve your highest ROI potential. The flag leaf is the leaf driving the photosynthesis that supports head and grain development, so you’ll want to put your biggest effort into protecting it.

You should wait for the flag leaf if disease pressure is low. If the conditions are right for disease pressure, however, it can pop up at any time—so pay close attention to conditions should you need to apply a preventative fungicide in your fields.
