Kazashi Fungicide (Isoprothiolane 40% EC) by IFFCO-MC | Complete Rice Blast Solution
The Japanese-tech specialist for healthy roots and blast-free Paddy.
Kazashi is a powerful systemic fungicide brought to you by the collaboration between IFFCO and Mitsubishi Corporation (Japan). Designed specifically for rice farmers, it offers a dual advantage: it cures the deadly Rice Blast disease (Leaf, Node, and Neck) and simultaneously rejuvenates the crop's root system. Unlike ordinary fungicides, Kazashi is absorbed quickly by the plant, providing long-lasting protection while making your paddy stronger against environmental stress.
Best For: Farmers seeking a "Green Window" solution during the Tillering to Booting stages to ensure quality grain filling and prevent "Akiochi" (root rot).
Why Choose This Product? Key Benefits
- ⏱️Rapid Action & Rainfastness: The EC formulation absorbs into the leaf within 1 to 2 hours. This makes it perfect for the monsoon (Kharif) season, as it won't wash away easily after spraying.
- ?️Complete Systemic Protection: Kazashi moves upwards (acropetally) inside the plant. It protects new growth and provides residual safety for 10 to 14 days, reducing the need for frequent spraying.
- ⏳Root Rejuvenation (Phytotonic Effect): It prevents "Akiochi" disease by stimulating new white root growth. This helps the plant absorb more nutrients, leading to better grain filling and fewer chaffy grains.
- ?️Bonus Pest Suppression: While primarily a fungicide, Kazashi also suppresses the Brown Plant Hopper (BPH) population, offering you extra value in your pest management program.
- ?Dual Mode of Action: It works as both a preventative shield (stopping spores from entering) and a curative medicine (stopping fungus growth inside the plant).

How It Works: Mode of Action
Kazashi operates differently from common fungicides like Tricyclazole, making it an excellent tool for managing resistance.
- Membrane Disruption: It inhibits the biosynthesis of phospholipids (Choline). Without these, the fungal cell wall collapses, and the fungus dies.
- Infection Blocker: It specifically stops the fungus from forming the "infection peg," preventing it from penetrating the rice leaf surface.
- Systemic Transport: Once sprayed, it enters the plant and travels through the xylem (water channels), protecting new leaves that grow after spraying.
Bonus: It also improves plant physiology, keeping leaves green longer (stay-green effect) for better photosynthesis.

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) |
|---|---|---|---|---|
| Rice (Standard) | 300 ml | 200 L | 1.5 ml | 60 Days |
| Rice (Severe) | 400 ml | 200 L | 2.0 ml | 60 Days |
| - | - | - | - | - |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. For Kazashi, this is strictly 60 days.
How to Apply: Best Practices
- Timing: Use during the vegetative stage (Tillering) to Booting stage. Do NOT use after the booting stage due to the 60-day PHI.
- Mixing: Compatible with Cartap and Fipronil. Do NOT mix with alkaline products like Bordeaux mixture or Lime Sulfur.
- Coverage: Ensure full foliar coverage using at least 200 Liters of water per acre.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Warning: Toxic to fish; do not use in paddy fields connected to aquaculture.
Frequently Asked Questions
1. Can I use Kazashi for late-stage Neck Blast?
It is recommended only if you are more than 60 days away from harvest. If the crop is already milking or heading, avoid Kazashi to prevent residue issues.
2. Does it control insects?
Yes, while it is a fungicide, it has a documented side effect of suppressing Brown Plant Hopper (BPH) populations, helping prevent outbreaks.
3. Is it safe for Basmati rice export?
Due to the 60-day PHI and strict MRLs in the EU, Kazashi is not recommended for Basmati rice destined for the European market. It is safe for domestic use if the timeline is followed.
4. Can I mix it with other fungicides?
Yes, it is compatible with Tricyclazole or Hexaconazole, but usually, Kazashi alone is sufficient for blast unless resistance is suspected.
5. What is the "Phytotonic" effect?
This refers to Kazashi's ability to stimulate root health, prevent root rot (Akiochi), and improve nutrient uptake, leading to a healthier, greener crop.
