Miravis® Duo Fungicide (Syngenta)
The Ultimate Dual-Action Shield against Alternaria, Scab, and Powdery Mildew.
Miravis® Duo is a premium, broad-spectrum fungicide designed by Syngenta to protect high-value crops like Almonds, Potatoes, and Vegetables. It combines two powerful technologies: ADEPIDYN® (Pydiflumetofen) and Difenoconazole.
Best For: Growers looking for "prevention plus cure." It locks into the leaf surface to stop diseases before they start, while also penetrating the tissue to clean up existing infections.
Why Choose Miravis Duo? Key Benefits
- ⏱️Fast Absorption & Curative Action: Starts working immediately. It has "kick-back" activity to stop fungi that have already started germinating.
- ?️Double-Lock Protection: Combines two modes of action (Group 7 + Group 3) to attack the fungus at two different weak points, reducing the risk of resistance.
- ⏳Long-Lasting Residual: The ADEPIDYN® technology creates a reservoir in the waxy layer of the leaf, providing extended protection even weeks after spraying.
- ?️Excellent Rainfastness: Becomes rainfast within just 1 hour of application, making it perfect for unpredictable spring weather.
- ?Greening Effect (Plant Health): Keeps leaves greener for longer by reducing plant stress, which can lead to better photosynthesis and higher yields.

How It Works: Mode of Action
[Image of fungal cell mitochondria inhibition]Miravis Duo attacks fungal pathogens on two fronts to ensure complete control:
- Energy Blockade (Pydiflumetofen): Targets the mitochondria (power plant) of the fungus. It shuts down energy production, stopping spores from germinating on the leaf surface.
- Cell Wall Destruction (Difenoconazole): Interferes with sterol biosynthesis. This prevents the fungus from building cell walls, effectively stopping the growth of the fungus inside the plant tissue.
- Synergistic Defense: The SDHI stays on the surface for protection, while the DMI moves inside (translaminar) to cure early infections.
Result: The fungus runs out of energy and cannot grow, leading to rapid pathogen death.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Tree Nuts (Almonds, Walnuts) | Alternaria Leaf Spot, Scab, Hull Rot (suppression), Anthracnose, Brown Rot. |
| Potatoes | Early Blight, Brown Spot, White Mold (suppression), Grey Mold (suppression). |
| Vegetables (Tomato, Onion) | Powdery Mildew, Purple Blotch, Stemphylium Leaf Blight, Septoria. |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Almonds / Tree Nuts | 400 ml | 200 L | 2.0 ml/L | 14 Days |
| Potatoes | 400 ml | 150 - 200 L | 2.0 - 2.5 ml/L | 14 Days |
| Fruiting Vegetables (Tomato/Pepper) | 300 - 400 ml | 200 L | 1.5 - 2.0 ml/L | 0 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Water volume may vary based on canopy size; adjust dose per liter accordingly to maintain dose per acre.
How to Apply: Best Practices
- Timing: Apply preventatively (before disease is visible) or at the very first sign of infection. For Potatoes, apply every 7-14 days.
- Mixing: Use the WALES method. Add Miravis Duo (Suspension Concentrate) after Wettable Powders but before Emulsifiable Concentrates (ECs). Avoid mixing with ECs in very cold water to prevent "gunk."
- Coverage: Ensure thorough coverage of the foliage. While Difenoconazole is translaminar (moves through the leaf), good spray coverage ensures the best results.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Re-entry into the field is safe after 12 hours.
Frequently Asked Questions
1. Is Miravis Duo rainfast?
Yes, it is rainfast within 1 hour of application. The ADEPIDYN® technology binds tightly to the waxy layer of the plant.
2. Can I use it for Botrytis (Grey Mold)?
Miravis Duo provides suppression of Botrytis and Sclerotinia (White Mold). For heavy pressure, it is a great rotation partner, but specific Botrytis products (like Miravis Prime) might be needed for severe outbreaks.
3. What is the "Green Effect"?
Farmers often notice that crops treated with Miravis Duo stay greener longer. This is because the SDHI component reduces plant stress and delays aging (senescence), allowing for a longer period of photosynthesis and better yield.
4. How many times can I spray it?
Do not spray more than 2 times consecutively. You must rotate with a different group of fungicide to prevent resistance. The total annual limit is usually around 4 applications per year (check local label).
5. Is it compatible with other products?
Yes, it is generally compatible. However, be careful when mixing with Emulsifiable Concentrates (ECs) or Copper fungicides. Always do a small jar test first.
