Curative "Kick-Back" Action: Stops infection even if applied 24–48 hours after the disease starts. It arrests fungal growth immediately.
-
🛡️
Systemic Protection: Unlike surface sprays, Win enters the plant and moves upwards, protecting new leaves that weren't even there when you sprayed.
-
⏳
Long-Lasting Defense: Provides extended protection (up to 30 days depending on the crop), reducing the need for frequent re-spraying.
-
🌧️
Rainfast Quickly: Absorbs into the leaf within 1 to 2 hours, making it safe to use during monsoon seasons.

How It Works: Mode of Action
Win 25% EC works by targeting the fungal cell walls.
- Stops Construction: It inhibits the production of Ergosterol, a vital component that fungi need to build their cell membranes. Without this, the fungus collapses and dies.
- Systemic Movement (Acropetal): Once sprayed, the leaves absorb the chemical. It travels upwards through the plant's water system (xylem) to protect the tips and new growth.
- Translaminar Action: It can move from the top of the leaf to the bottom, killing hidden pests like rusts that hide on the underside of leaves.
Note: Because it moves upwards, ensure you spray the lower leaves well for full plant coverage.
Target Crops & Pests
[Image of sheath blight in rice]| Crop | Target Pest(s) |

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Using less leads to resistance; using more wastes money.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Wheat | 200 ml | 200 L | 1 ml/L | 30 Days |
| Rice | 200 ml | 200 L | 1 ml/L | 30 Days |
| Groundnut | 200 ml | 200 L | 1 ml/L | 15 Days |
| Tea | 50 - 100 ml | 150 - 200 L | 0.5 ml/L | 7 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Critical for export crops like Tea and Basmati Rice.
How to Apply: Best Practices
- Timing: For best results, spray prophylactically (before disease starts) or immediately upon seeing the first symptoms (lesions/spots).
- Mixing: Add the required quantity of Win 25% EC to a small amount of water and stir well before adding to the main tank. It turns into a white, milky emulsion.
- Coverage: Use a hollow cone nozzle for fine misting. Ensure lower leaves are covered as the chemical moves up, not down.
- Safety: Always wear PPE (gloves, mask, goggles). Avoid spraying near fish ponds as it is toxic to aquatic life. Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I mix Win 25% EC with other chemicals?
Yes, it is generally compatible with most insecticides and fungicides. A common tank mix is with Mancozeb to broaden the spectrum and prevent resistance.
2. Is Win 25% EC effective if it rains?
Yes, it becomes rainfast within 1 to 2 hours of application. If it rains after this period, re-spraying is usually not required.
3. Can this be used on vegetables?
While Propiconazole is effective on many crops, always strictly follow the label. It is not recommended for vegetables with very short harvesting cycles due to residue risks.
4. How does it help with Wheat Karnal Bunt?
A prophylactic spray at the boot leaf stage helps inhibit spore germination, preventing the grains from turning into black powdery masses.
5. Why is the PHI for Tea only 7 days?
Tea is harvested frequently. Win 25% EC degrades to safe levels within a week, fitting perfectly into the standard plucking rounds of tea plantations.
