Stop fungal diseases before they start with Coromandel’s trusted crop protector.
Jatayu (Chlorothalonil 75% WP) is a broad-spectrum contact fungicide designed to protect your high-value crops like Potato, Groundnut, and Vegetables. Unlike simple chemical sprays, Jatayu acts as a "multi-site" shield, preventing fungus from entering the plant leaf.
Best Used For: Managing resistance in crops and providing a strong protective barrier against Blights, Leaf Spots, and Mildews.

-
⏱️
Stops Disease Fast: Acts as an "anti-sporulant," meaning it stops the fungus from producing new spores and spreading.
-
🛡️
Broad Spectrum Shield: Provides powerful protection against Early and Late Blight, Tikka Leaf Spot, and Fruit Rots.
-
⏳
Long-Lasting Action: Stays effective on the leaf surface for up to 10 days, reducing the need for frequent re-spraying.
-
🌧️
Excellent Rainfastness: Once dried, it sticks firmly to the leaf and does not wash away easily during rain or irrigation.

How It Works: Mode of Action
Jatayu works differently than modern systemic medicines. It is a "Multi-Site" inhibitor, meaning it attacks the fungus from many angles at once.
- Energy Blockade: It stops the fungus cells from producing energy (ATP) by disrupting their respiration process.
- Enzyme Shutdown: It binds to essential enzymes inside the fungus, making them unable to function.
- Spore Prevention: It prevents fungal spores from germinating on the leaf, effectively stopping the disease cycle before it begins.

Target Crops & Pests

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 (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Groundnut | 350 - 600 g | 240 - 300 L | ~ 2.0 g | 14 Days |
| Potato | 350 - 500 g | 240 - 300 L | ~ 2.0 g | 14 Days |
| Vegetables | 400 - 600 g | 200 - 300 L | ~ 2.0 - 2.5 g | 5 - 7 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply strictly as a preventive measure (before disease starts) or at the very first sign of spots on leaves.
- Mixing: Do NOT dump the powder directly into the tank. First, mix the powder with a little water in a bucket to make a smooth "slurry" (cream-like paste), then add to the main tank.
- Coverage: This is a contact fungicide. It must cover the entire leaf surface (top and bottom) to work. Use high water volume.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid inhaling the dust while mixing.
Frequently Asked Questions
1. Is Jatayu a systemic or contact fungicide?
Jatayu is a pure Contact fungicide. It stays on the leaf surface and does not enter the plant system. Therefore, thorough coverage is essential.
2. Can I mix Jatayu with oil-based tonics or stickers?
No. Do NOT mix Jatayu with oils or oil-based insecticides. Mixing with oil can cause the chemical to penetrate the leaf and burn the crop (phytotoxicity).
3. Can I use it on flowering crops?
Avoid spraying on open flowers or active blooms, especially on fruit crops like grapes, as it may cause russeting (scarring) on the fruit skin.
4. Does it work on Downy Mildew?
Yes, it is effective against Downy Mildew and Anthracnose, but it is best used in rotation with systemic fungicides for complete control.
5. What is the dose for a 15-litre knapsack sprayer?
For a standard 15-litre tank, use approximately 30 to 40 grams of Jatayu powder, depending on the crop stage.
