Syngenta Revus® Fungicide (Mandipropamid 23.4% SC)
The Ultimate Weather-Proof Shield Against Downy Mildew and Late Blight.
Farming in the rainy season is risky. A sudden shower can wash away your fungicide, leaving your crops vulnerable to devastating diseases like Downy Mildew and Late Blight. Syngenta Revus® solves this problem with its unique LOK + FLO™ Technology.
Revus is a highly effective, low-dose fungicide that bonds to the leaf surface and flows inside the tissue. It is designed to protect Grapes, Potatoes, and Tomatoes even under the toughest monsoon conditions.

How It Works: LOK + FLO™ Mode of Action
Revus works on a unique "Lock and Flow" principle that makes it superior to older fungicides like Mancozeb.
- LOK (Adsorption): Immediately after spraying, the molecule binds tightly to the waxy layer of the leaf. This "locks" the medicine in place, making it resistant to rain.
- FLO (Translaminar Movement): The active ingredient flows through the leaf tissue to reach the underside. This kills hidden fungus that simple contact sprays miss.
- Inhibition: It stops the fungus from building cell walls, effectively preventing spore germination and stopping the disease before it damages the crop.
Note: Revus acts on the phospholipid biosynthesis of the fungal cell wall (FRAC Group 40).
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Grapes | Downy Mildew (Plasmopara viticola) |
| Potato & Tomato | Late Blight (Phytophthora infestans) |
| Cucurbits (Cucumber, Melons) | Downy Mildew (Pseudoperonospora cubensis) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results, as water volume may vary based on canopy size.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Grapes | 160 - 200 ml | 200 L | 0.8 - 1.0 ml | 5 (Domestic) / 14 (Export) |
| Potato | 160 - 200 ml | 200 L | 0.8 - 1.0 ml | 3 - 14 Days* |
| Tomato | 160 - 200 ml | 200 L | 0.8 - 1.0 ml | 5 Days |
*PHI = Pre-Harvest Interval: Check specific bottle label for local Potato regulations. Generally safe to harvest 5 days after spray.
How to Apply: Best Practices
- Timing: Apply Preventively (before disease starts). Start spraying at the first sign of cloudy weather or rain forecasts.
- Mixing: Fill half the tank with water. Add Revus SC and mix well. Then add other tank-mix partners (if any).
- Coverage: Revus moves through the leaf (translaminar), but good coverage ensures the "LOK" mechanism works best. Ensure nozzle pressure is adequate.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Does rain wash away Revus?
No. Revus becomes rainfast within 1 hour. Once dry, it bonds to the leaf wax and won't wash off, even in heavy monsoon rains.
2. Can I mix Revus with other products?
Yes, Revus is compatible with contact fungicides like Mancozeb and Chlorothalonil. Mixing with Mancozeb is highly recommended to prevent resistance buildup.
3. Is Revus a curative fungicide?
Revus is primarily a preventive fungicide. While it has some kick-back action (1-2 days), it works best when applied before the disease spreads.
4. How often should I spray?
Under normal conditions, every 7-10 days. In severe disease pressure (continuous rain), reduce the interval to 5-7 days.
5. How is it different from Ridomil Gold?
Ridomil is fully systemic (moves up the plant), while Revus is translaminar (moves through the leaf) and has superior rainfastness. Revus is excellent for rotation to prevent resistance to Ridomil.
