Achibu Fungicide (Fenoxanil 5% + Isoprothiolane 30% EC)
The Ultimate "Shield & Sword" Protection Against Rice Blast
Achibu by Nichino India is a premium, dual-action fungicide designed specifically for Paddy (Rice) farmers. It combines Japanese technology to fight the devastating Rice Blast fungus (Magnaporthe oryzae). unlike standard fungicides, Achibu works in two ways: it stops the fungus from entering the plant (Shield) and destroys existing infections inside the plant (Sword).
Best For: Farmers looking for a one-stop solution for Leaf Blast and Neck Blast (Rotten Neck) while improving crop greenness and yield quality.
Why Choose This Product? Key Benefits
- ⏱️Fast Absorption & Rainfastness: Absorbs rapidly into the leaf. It becomes rainfast within 2-3 hours, making it perfect for the monsoon season.
- ?️True Dual Mode of Action: Contains two powerful chemicals. One stops the fungus from penetrating the leaf, and the other kills the fungus already inside.
- ⏳Super Systemic Protection: Moves upward (acropetally) inside the plant to protect new leaves and the emerging panicle neck that haven't even been sprayed yet.
- ?️Resistance Fighter: Ideal for managing fungus that has become resistant to older, single-chemical fungicides.
- ?Phytotonic "Greening" Effect: Boosts plant immunity and keeps leaves greener for longer, leading to better grain filling and higher yields.

How It Works: Mode of Action
Achibu employs a unique synergy to control Rice Blast at different stages of the fungal lifecycle.
- The Shield (Fenoxanil): Blocks melanin production in the fungus. Without melanin, the fungus cannot create the pressure needed to punch through the rice leaf, effectively locking it out.
- The Sword (Isoprothiolane): Disrupts the lipid metabolism (fat processing) of the fungus. This destroys the fungal cell walls, stopping growth and drying up existing lesions.
- Immunity Booster: Triggers the rice plant's own defense system, increasing proteins that help the plant fight off stress and disease naturally.
This multi-site action makes it very difficult for the fungus to develop resistance.
Target Crops & Pests

|---|---|
| Paddy (Rice) | Leaf Blast (Magnaporthe oryzae) |
| Paddy (Rice) | Neck Blast (Rotten Neck) |
| Paddy (Rice) | 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 (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Paddy (Rice) | 400 ml | 150 - 200 Liters | 2.0 - 2.5 ml | 30 Days |
| Drone Spraying | 400 ml | 10 Liters (ULV) | Follow SOP | 30 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: For best results against Neck Blast, spray at the Booting Stage or at 10% Panicle Emergence. Do not wait for symptoms to appear on the neck.
- Mixing: Achibu is an EC formulation. Pour the required amount into water and stir well to form a white emulsion. It is compatible with insecticides like Chlorantraniliprole (Coragen) and Spinetoram.
- Coverage: Use sufficient water (minimum 150 liters/acre for manual pumps) to ensure the spray reaches the lower plant parts.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying near fish ponds as it is toxic to aquatic life.
Frequently Asked Questions
1. Can Achibu cure blast after it has already started?
Yes, due to the Isoprothiolane content, it has curative properties that can stop the growth of existing leaf blast lesions. However, for Neck Blast, preventative spraying at the booting stage is highly recommended.
2. Does Achibu help improve yield?
Yes. Apart from disease control, it provides a "Phytotonic" effect that keeps the flag leaf green for longer, aiding in better grain filling and potentially higher yields.
3. Is it safe to mix Achibu with insecticides?
Generally, yes. It is physically compatible with common rice insecticides like Chlorantraniliprole (for Stem Borer) and Spinetoram. Avoid mixing with highly alkaline products like Bordeaux mixture.
4. What is the approximate price of Achibu per acre?
The cost typically ranges between ₹500 to ₹700 per acre depending on the local dealer pricing and pack size purchased, making it a cost-effective premium solution.
5. Can I use a drone to spray Achibu?
Yes, Achibu's EC formulation is suitable for drone application. Ensure you follow standard SOPs (height and speed) to ensure the spray penetrates deep into the crop canopy.
