Ergon Fungicide by Rallis India (Kresoxim-methyl 44.3% SC)
The "One-Shot" Solution for Disease Control and Higher Yields
Ergon (often referred to as Eragon) is a premium, broad-spectrum fungicide developed by Rallis India (Tata Enterprise). It is designed not just to kill fungus but to actually make your crop healthier.
What makes it special? Powered by Kresoxim-methyl, Ergon stops diseases like Blast and Mildew while providing a "Phytotonic Effect"—meaning it keeps leaves greener for longer, leading to better quality and higher yields. It works on the surface and inside the leaf to give you complete protection.
Why Choose This Product? Key Benefits
-
⏱️
Triple Action Power: Protects the plant before infection (Preventive), stops disease spread (Curative), and prevents spore formation (Eradicative).
-
🛡️
Mesostemic Technology: The chemical spreads across the leaf surface and moves through the leaf layers (translaminar), reaching pests hiding underneath or in hard-to-reach spots.
-
⏳
Long-Lasting Result: It sticks to the waxy layer of the plant, releasing slowly to provide protection for 15 to 20 days, reducing the need for frequent sprays.
-
🌧️
Excellent Rainfastness: Once the spray dries (usually 1–4 hours), it resists washing off by rain, making it perfect for monsoon crops like Paddy and Soybean.
-
🌿
Greening (Phytotonic) Effect: It helps the plant absorb more Nitrogen and delays aging. This keeps leaves green, improves grain filling in rice, and enhances fruit quality in chillies.

How It Works: Mode of Action
Ergon works by cutting off the energy supply to the fungus. Think of it as "choking" the fungus so it cannot breathe or grow.
- Energy Blockade: It enters the fungal cell and blocks the mitochondria (the power plant of the cell). This stops the production of ATP (energy).
- Stops Germination: It prevents fungal spores from sprouting, stopping the infection before it starts.
- Gas Phase Action: After spraying, a small amount of the chemical turns into vapor, creating a protective cloud that reaches parts of the plant the sprayer might have missed.
Result: The fungus dies from starvation, and the plant remains healthy and green.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Paddy (Rice) | Blast (Leaf & Neck), Sheath Blight |
| Grapes | Downy Mildew, Powdery Mildew |
| Chilli, Potato, Tomato | Fruit Rot, Die Back, Powdery Mildew, Early & Late Blight |
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 L | 1 ml | 30 |
| Chilli & Veg | 200 ml | 200 L | 1 ml | 25 |
| Grapes | 240 - 280 ml | 200 - 400 L | 1 - 1.5 ml | 7 (Domestic) |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply as a preventive spray (before disease is severe) or at the early stages of disease appearance. For Rice, apply at the "boot leaf" stage for best results.
- Mixing: Do not mix with highly alkaline products like Bordeaux mixture or Lime Sulphur. It is compatible with most common insecticides like Acephate or Imidacloprid.
- Coverage: Ensure thorough coverage of the foliage. The "vapor action" helps, but good spraying technique is key.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying near fish ponds or water bodies.
Frequently Asked Questions
1. What is the main use of Ergon Fungicide?
It is used to control severe fungal diseases like Blast in paddy, Mildew in grapes, and Fruit Rot in chillies. It also improves crop quality by keeping leaves green.
2. Is Ergon safe for humans?
Yes, Ergon has a "Green Label," meaning it is slightly toxic and generally safe for applicators when used with standard safety gear. However, it is toxic to fish and aquatic life.
3. Can I mix Ergon with antibiotics?
Yes, for bacterial diseases in rice, you can tank-mix Ergon with antibiotics like Streptocycline. Always do a small jar test first.
4. Does rain wash away Ergon?
Ergon has high rainfastness. Once the spray dries on the leaf (usually within 1 to 4 hours), it won't wash off easily, making it great for the rainy season.
5. How does it help increase yield?
Ergon reduces the stress hormone (ethylene) in plants and improves nitrogen absorption. This keeps the plant healthier and greener for longer, resulting in better grain filling and higher quality produce.
