Ergon Fungicide (Kresoxim-methyl 44.3% SC) - Rallis India
The "Green Label" expert for Paddy, Grapes, and Vegetables.
Ergon (often misspelled as Eragon) is a premium, high-tech fungicide developed by Rallis India (Tata Enterprise). It is designed to fight tough fungal diseases while actively boosting your crop's health.
Unlike ordinary fungicides that only kill germs, Ergon acts as a tonic for your plants. It keeps leaves greener for longer, delays aging, and helps the plant absorb nitrogen better. This leads to higher quality produce and better market prices. It is the perfect choice for high-value crops like Grapes, Chilli, and Basmati Rice.
Why Choose This Product? Key Benefits
- ⏱️Double Action Power: Protects healthy plants from getting sick (Preventative) and stops the spread of disease in infected plants (Curative).
- ?️Mesostemic Technology: The medicine moves through the leaf to kill hidden fungus on the underside and creates a "vapor cloud" to reach areas the spray nozzle missed.
- ⏳Long-Lasting Protection: It sticks to the leaf surface and releases slowly, providing protection for 15 to 20 days, reducing your need for frequent sprays.
- ?️Excellent Rainfastness: The SC formulation sticks quickly. Once the leaves are dry (1-4 hours), the medicine won't wash off easily during monsoon rains.
- ?Phytotonic "Greening" Effect: It reduces stress hormones (ethylene) in the plant, keeping leaves green and healthy (photosynthetic) for longer, which increases yield quality.

How It Works: Mode of Action
Ergon works by cutting off the energy supply to the fungus. Imagine it unplugging the power cord of the disease cells.
- Stops Energy Production: It blocks mitochondrial respiration (breathing) in fungal cells. Without energy (ATP), the fungus dies.
- Spore Killer: It prevents new fungal spores from germinating, stopping the infection before it starts.
- Translaminar & Vapor Action: It moves from the top of the leaf to the bottom and creates a gas phase to protect hidden parts of the plant.
This "Mesostemic" action ensures that even if you miss a spot while spraying, the vapors help cover the gap.

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) |
|---|---|---|---|---|
| Paddy (Rice) | 200 ml | 200 Litres | 1 ml | 30 |
| Grapes | 240 - 280 ml | 200 - 400 Litres | 1.0 - 1.5 ml | 7 |
| Chilli & Potato | 200 ml | 200 Litres | 1 ml | 25 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Best applied preventatively (before disease is severe) or at early stages. For Paddy, apply at the "Boot Leaf" stage.
- Mixing: Compatible with most insecticides and antibiotics (like Streptocycline). Avoid mixing with Bordeaux mixture or alkaline products.
- Coverage: Ensure good coverage, but the "vapor action" will help reach hidden leaves.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Is Ergon safe for fish?
No. Kresoxim-methyl is toxic to aquatic life. Do not use near fish ponds or wash sprayers in rivers.
2. Can I use it on export grapes?
Yes, but be careful with the harvest interval (PHI). European markets often require a longer wait (30+ days) than the Indian standard. Check with your export advisor.
3. What is the "Greening Effect"?
Ergon reduces the aging hormone (ethylene) in plants. This keeps leaves green and working longer, which results in better grain filling and fruit quality.
4. How fast does it become rainproof?
It has excellent rainfastness. Once the spray dries completely on the leaf (usually 1-3 hours), light rain will not wash it off.
5. Should I use it repeatedly?
No. To prevent resistance, do not spray Ergon more than twice per season. Rotate with a different type of fungicide (like Mancozeb) in between.
