Kizuna Fungicide (Dimethomorph 50% WP) by IFFCO-MC
Advanced Japanese Technology for Downy Mildew & Late Blight Control
Kizuna (Dimethomorph 50% WP) is a powerful systemic fungicide brought to you by IFFCO-MC, a joint venture between the trusted Indian cooperative IFFCO and Mitsubishi Corporation, Japan. Designed specifically to fight "water mold" diseases, Kizuna provides deep protection for grape and potato crops.
Best For: Farmers seeking a solution for Oomycete diseases that have developed resistance to older chemicals like Metalaxyl. It works by stopping the fungus from building its cell walls.
Why Choose This Product? Key Benefits
- ⏱️Curative "Kick-Back" Action: Stops infection even if applied 24 to 48 hours after the disease starts incubating.
- ?️Stops Disease Spread (Anti-Sporulant): Prevents the fungus from producing spores, effectively breaking the chain of infection in your field.
- ⏳Long-Lasting Protection: Provides extended safety for 10-12 days, reducing the need for frequent re-spraying.
- ?️Excellent Rainfastness: Becomes rain-safe within 2 to 3 hours of application, making it ideal for monsoon usage.
- ?Translaminar Movement: Penetrates the leaf surface to reach the underside, killing hidden pathogens where sprays often miss.

How It Works: Mode of Action
Kizuna attacks the fungus at a structural level. It targets the Cellulose Synthase enzyme, which is vital for the fungus to build its cell walls.
- Cell Wall Destruction: It disrupts the formation of the fungal cell wall, causing the cells to burst (lysis) due to internal pressure.
- Translaminar Penetration: Upon spraying, the chemical absorbs into the leaf wax and moves to the opposite side, protecting the entire leaf tissue.
- Cycle Breaking: It stops the production of zoospores and sporangia, preventing the disease from jumping to healthy plants.
Note: Kizuna is locally systemic (translaminar) but does not move fully from roots to shoots.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Grapes | Downy Mildew (Plasmopara viticola) |
| Potato | Late Blight (Phytophthora infestans) |
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) |
|---|---|---|---|---|
| Grapes | 400 g | 300 - 400 L | ~ 1.0 - 1.5 g | 25 Days |
| Potato | 400 g | 300 - 400 L | ~ 1.0 - 1.5 g | 16 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting to ensure residue-free produce for export.
How to Apply: Best Practices
- Timing: Apply prophylactic sprays (preventive) at the 3-5 leaf stage in grapes, or immediately when weather conditions favor disease (cloudy, humid).
- Mixing (Slurry Method): Since this is a Wettable Powder (WP), first mix the required dose in a small bucket of water to form a smooth paste (slurry), then add this to the main tank while stirring.
- Coverage: Use high water volume to ensure the crop canopy is thoroughly drenched. Coverage of the lower leaf surface is critical.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid washing spray equipment in water bodies.
Frequently Asked Questions
1. Is Kizuna fully systemic?
It is "translaminar" or locally systemic. It penetrates the leaf to reach the other side but does not travel from the roots to the top of the plant.
2. Can I mix Kizuna with other fungicides?
Yes, it is highly recommended to tank-mix Kizuna with contact fungicides like Mancozeb or Chlorothalonil to broaden protection and prevent resistance.
3. What happens if it rains after spraying?
Kizuna is rainfast within 2 to 3 hours. If it rains after this period, the product has already penetrated the leaf and will remain effective.
4. Why is the Pre-Harvest Interval (PHI) important for Grapes?
For export-quality grapes, you must stop spraying 25 days before harvest to ensure chemical residues drop below European Union (EU) limits.
5. How is Kizuna different from Metalaxyl?
Kizuna belongs to the CAA group and is effective against strains of mildew that have become resistant to phenylamides like Metalaxyl.
