Agni Fungicide by Coromandel (Tricyclazole 75% WP)
The Ultimate "Fire" Against Rice Blast Disease
Agni is a specialized systemic fungicide designed to protect your Paddy (Rice) crops from the devastating impact of Blast disease. Manufactured by Coromandel International, Agni uses the power of Tricyclazole (75% WP) to prevent fungal attacks before they start.
Whether you are fighting Leaf Blast, Node Blast, or the crop-destroying Neck Blast, Agni provides a robust shield. It not only stops the disease but also provides a "phytotonic" effect, keeping your crop green, healthy, and ensuring better grain quality at harvest.
Why Choose Agni Fungicide? Key Benefits
- ⏱️Rapid Absorption: Absorbed by the plant leaf within 1 to 2 hours, ensuring immediate protection.
- ?️Systemic Action: Moves upward (acropetally) within the plant to protect new leaves and growth tips automatically.
- ⏳Long-Lasting Defense: Provides durable resistance against Blast, reducing the need for frequent re-spraying.
- ?️Excellent Rainfastness: Once absorbed (1-2 hours), it does not wash off easily during heavy rains, making it perfect for the monsoon season.
- ?Stay-Green Effect: Improves photosynthetic efficiency, leading to shinier grains and higher yields.

How It Works: Mode of Action
Agni works by targeting the specific biology of the Blast fungus (Magnaporthe oryzae). It acts as a shield rather than a sword.
- Inhibits Melanin: Agni stops the fungus from producing melanin, a pigment necessary for the fungal cell wall to harden.
- Prevents Penetration: Without hardened cell walls, the fungus cannot generate the pressure needed to punch through the rice leaf's surface.
- Stops Infection: The fungal spore fails to enter the plant tissue, effectively neutralizing the threat before damage occurs.
Note: Because Agni prevents entry, it is most effective when used preventively or at the very first sign of disease.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Paddy (Rice) | Leaf Blast |
| Paddy (Rice) | Node Blast |
| Paddy (Rice) | Neck (Panicle) Blast |
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) |
|---|---|---|---|---|
| Paddy (Foliar Spray) | 120 - 160 g | 150 - 200 L | 0.6 - 0.8 g | 30 Days |
| Seed Treatment | 3 g / kg Seed | Make Slurry | N/A | - |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: For Leaf Blast, spray immediately when spots appear. For Neck Blast, spray at the "late booting" stage (just before panicles fully emerge).
- Mixing: Fill the tank halfway with water, add the required Agni powder (pre-dissolved in a bucket), and mix well. Do not mix with alkaline substances like Bordeaux mixture.
- Coverage: Ensure uniform coverage of the foliage. Agni is rainfast after 1-2 hours.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Is Agni effective for Basmati Rice export?
No. The European Union (EU) has very strict residue limits (MRL) for Tricyclazole. If you are growing Basmati for export to the EU or US, avoid using Agni to prevent shipment rejection.
2. Does Agni cure the disease after it spreads?
Agni is primarily a preventive fungicide. It works best before the fungus enters the leaf. If the disease is already severe, consider tank-mixing with a curative fungicide (like Isoprothiolane or Kasugamycin) after consulting an expert.
3. Can I use Agni in the nursery?
Yes. Treating seeds or dipping seedling roots in Agni solution protects the young crop from early blast attacks for up to 20-30 days after transplanting.
4. What is the rainfastness of Agni?
Agni is rapidly absorbed by the plant. It becomes rainfast within 1 to 2 hours of application, meaning rain after this period will not reduce its effectiveness.
5. Why do farmers call Agni "Phytotonic"?
Apart from disease control, Agni helps the rice plant retain chlorophyll (greenness). This leads to better photosynthesis, heavier grains, and shiny produce at harvest.
