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 farmers choose itWhy 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).

Product scienceHow It Works: Mode of Action

Kazashi operates differently from common fungicides like Tricyclazole, making it an excellent tool for managing resistance.

  1. Membrane Disruption: It inhibits the biosynthesis of phospholipids (Choline). Without these, the fungal cell wall collapses, and the fungus dies.
  2. Infection Blocker: It specifically stops the fungus from forming the "infection peg," preventing it from penetrating the rice leaf surface.
  3. 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.

How to applyDosage & Application Guide

The Golden Rule: Always follow the "Dose per Acre" for accurate results.

How to applyDosage per Acre, Litre, & Pre-Harvest Interval (PHI)
CropDose (ml / Acre)Water (L / Acre)Dose (ml / Litre)PHI (Days)
Rice (Standard)300 ml200 L1.5 ml60 Days
Rice (Severe)400 ml200 L2.0 ml60 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.

Useful detailsHow 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.
