Fungicides Are Not Created Equal

What Is an Effective Mode of Action?
You may be familiar with the term “mode of action” when it comes to herbicide selection, but it’s also important to understand modes of action in fungicide products. Overusing the same fungicide modes of action can lead to resistant populations of fungal pathogens and poor disease control, ultimately limiting yield potential.

Choose Wisely to Maintain Fungicide Performance
While multiple modes of action are important, it’s also crucial to choose products with effective modes of action. Not all fungicides control disease in the same way, so you should properly identify pathogens and use products that will effectively control those diseases.

Fungicides are only effective when they are applied at the right time according to label instructions. A late application of a preventive fungicide when disease pressure is already heavy won’t be effective and can promote fungicide resistance.

Follow these management practices to help maintain fungicide efficacy:

• Use non-chemical disease management methods (plant disease-resistant seed varieties, use crop rotation).
• Use fungicide mixes that contain multiple modes of action.
• Rotate fungicide modes of action if you make more than one application in a season.
• Follow label rates and application timing.
• Apply fungicides based on scouting observations and risk for yield loss.
• Use integrated pest management practices to maintain plant health.

Two Effective Fungicide Options
DuPont™ Aproach® Prima fungicide has two modes of action and preventive, curative and eradicant activity to control all phases of the pathogen life cycle. Five‑year DuPont Crop Protection performance trials tested the ability of fungicides in soybean and corn to increase grower profitability. Across 160 trials, Aproach® Prima demonstrated a positive return on investment for both corn and soybeans.

Soybean Yield

In heavy soybean white mold areas, DuPont™ Aproach® fungicide delivers effective control. It is the only disease control technology that protects plants internally and externally, with better distribution throughout the canopy and outstanding rainfastness for a visibly better crop.
