Kazashi Fungicide (Isoprothiolane 40% EC): The Japanese Expert for Rice Blast
Stop Rice Blast and rejuvenate your paddy with the dual-power of IFFCO-Mitsubishi technology.
Kazashi is a world-class systemic fungicide brought to you by the collaboration between IFFCO and Mitsubishi Japan. It is designed specifically to fight the devastating Rice Blast disease (Leaf, Node, and Neck Blast). Unlike older chemicals that wash away, Kazashi enters the plant system to cure the disease from the inside while also boosting root health for higher yields.
Best For: Paddy farmers facing blast attacks or looking for preventative crop health (Green Window protection).

How It Works: Mode of Action
Kazashi works in two powerful ways to protect your crop:
- Destroys Cell Walls: It inhibits the fungus from building essential cell walls (phospholipids), causing the disease spores to collapse and die.
- Stops Fungal Entry: It specifically stops the fungus from forming the "infection peg" (the needle it uses to pierce the leaf), acting as a strong shield.
- Root Rejuvenation: It boosts the plant's metabolism, helping it grow new white roots even in anaerobic (low oxygen) soil conditions.
*Result: The fungus cannot grow, and the plant becomes stronger to resist stress.

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) | 300 - 400 ml | 200 Liters | 1.5 - 2.0 ml | 60 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Do not spray after the Booting stage.
How to Apply: Best Practices
- Timing (Green Window): Spray between the Tillering and Booting stages. Do not spray during flowering or milking stages due to the 60-day PHI.
- Mixing: Compatible with Cartap, Fipronil, and Coragen. Do NOT mix with Bordeaux mixture, Lime Sulfur, or alkaline chemicals.
- Coverage: Use at least 200 Liters of water per acre. Good leaf coverage is essential for the chemical to penetrate.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I use Kazashi for Export/Basmati Rice?
Caution is advised. The European Union (EU) has very strict residue limits. If exporting to the EU, avoid this product. For domestic markets, it is safe if you follow the 60-day waiting period.
2. Does Kazashi kill insects like BPH?
While it is a fungicide, it suppresses the population of the Brown Plant Hopper (BPH). However, for heavy insect infestations, use a dedicated insecticide.
3. How quickly does it work if it rains?
Kazashi is formulated as an EC (Emulsifiable Concentrate), making it rainfast in 1 to 2 hours.
4. Can I use this in fields with fish farming?
No. Isoprothiolane is toxic to fish. Do not use in paddy fields where you are also practicing pisciculture (fish farming).
5. What is the best time to spray for Neck Blast?
For Neck Blast prevention, spray at the **Booting Stage** (just before the panicle emerges). Do not wait for the disease to appear on the neck.
