Delaro Fungicide FAQ

Delaro Product Overview


What is Delaro™ fungicide?

Delaro is a new fungicide from Bayer that offers an advanced formulation to deliver unmatched, broad-spectrum disease control in corn and soybeans, best-in-class dual mode of action residual and improved plant health. Learn more about the benefits of Delaro.

How does Delaro work?

The progressive movement of Delaro maximizes and extends its protection of your crop in a way other fungicides can’t. Delaro diffuses in and on the waxy surface of the plant. It then expands protection across the plant's exterior by moving via surface moisture, such as dew. Within the plant, Delaro is transported systemically throughout plant tissue for enhanced coverage. Delaro moves both on the inside and the outside of the plant.

What diseases can I control with Delaro?

Delaro fungicide is formulated with two heavy-hitting modes of action, together maximizing control of even the toughest diseases. In corn, Delaro has unmatched preventive and curative defense against yield-robbing diseases including gray leaf spot, northern corn leaf blightanthracnose leaf blight and southern rust. In soybeans, Delaro defends against frogeye leaf spot, brown spot, aerial blight and white mold. Explore the full list of diseases Delaro controls.

How is Delaro better than other popular fungicide brands?

Delaro has an improved active ingredient (AI) ratio. Delaro now contains 2.8x the rate of Proline® (compared to Stratego® YLD). This results in an unmatched broad spectrum of disease control; best-in-class, dual mode of action residual efficacy; improved plant health; and typically, higher yields. With Delaro, two broad-spectrum chemistries are working against your important diseases for the entire spray interval, rather than one mode of action shouldering the biggest load.

How does Delaro combat disease resistance development?

Delaro contains two powerful broad-spectrum modes of action in one product, which helps fight the important fungal diseases in corn and soybeans, even strobilurin-resistant frogeye leaf spot. According to the Fungicide Resistance Action committee (FRAC), a specialist technical group of CropLife International, the best way to prevent and manage disease resistance is by using multiple modes of action in tank mixes at labeled rates. For complete application details, review the Delaro fungicide label.





Delaro Application and Use


When should I apply Delaro?

This versatile fungicide has application flexibility in corn — at-tassel timing (VT to R2), in combination with a herbicide (V4 to V7) and/or in between (V8 to VT). In soybeans, the ideal time to first apply Delaro is prior to development of most common diseases, between R2 and R5, with applications repeated as necessary. To manage white mold, apply prior to disease development, at R1, with a second treatment at R3 or R4. Learn more about application timing on the Delaro fungicide label.

What application methods can I use with Delaro?

Delaro fungicide can be applied by air, ground or by chemigation and can be mixed with adjuvants, herbicides, insecticides and micronutrients for cost efficiency. Review the Delaro fungicide label for complete application instructions.

Why should I plan a Delaro fungicide application before disease appears?

When it comes to addressing plant stress and disease, it’s important that you not take a “wait and see” approach, but instead consider planning ahead to protect your crop yield potential. Between V4 and V7, corn plants go through a critical growth period that greatly influences yield potential. Even if disease symptoms are not yet visible, an early season application of Delaro can give your high-yielding hybrids the protection they need. Other benefits include healthier stalks and improved stress tolerance.
