Kizuna Fungicide (Dimethomorph 50% WP) – Expert Solution for Grapes & Potato
Stop Downy Mildew and Late Blight before they destroy your harvest with the power of Japanese technology.
Kizuna (Dimethomorph 50% WP) is a specialized systemic fungicide brought to you by IFFCO-MC. Designed specifically to fight "water molds" (Oomycetes), it provides robust protection for high-value crops like Grapes and Potatoes. Unlike older fungicides that wash off easily, Kizuna penetrates the leaf to stop disease from the inside out.
Best for: Farmers looking for a "Curative & Prophylactic" solution that stops disease spread and prevents spore formation.
Why Choose This Product? Key Benefits
-
⏱️
Stops Disease Fast: Acts as an anti-sporulant, meaning it stops the fungus from producing new spores and spreading to healthy plants.
-
🛡️
Double Action Defense: Works as both a preventative shield (prophylactic) and a cure (curative) if applied within 48 hours of infection.
-
⏳
Deep Leaf Penetration: Features "Translaminar Activity." When sprayed on the top of the leaf, it travels through to the underside where diseases hide.
-
🌧️
Rainfast in 2-3 Hours: The chemical absorbs quickly into the plant system, making it resistant to wash-off from rain shortly after spraying.
-
🌿
Export-Friendly: Safe for beneficial insects and has established MRLs for major export markets (when PHI is followed).

How It Works: Mode of Action
Kizuna works differently from older fungicides like Mancozeb or Metalaxyl, making it an excellent tool for managing resistance.
- Cell Wall Destruction: It disrupts the formation of the fungal cell wall (cellulose synthesis). Without a wall, the fungal cells burst and die.
- Translaminar Movement: The particles settle on the upper leaf surface and travel through the tissue to the lower surface, killing hidden fungi.
- Life-Cycle Break: It attacks the fungus at all stages—preventing spore germination, stopping growth, and preventing sporulation.
Note: This unique action breaks the "epidemic chain," stopping the disease from exploding across the field.
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. Do not under-dose water volume, as thorough coverage is essential for Oomycetes.
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
- Mixing (The Slurry Method): This is a Wettable Powder (WP). Do not dump it directly into the full tank. First, mix the required dose in a small bucket of water to make a smooth paste (slurry), then add this to the main tank while stirring.
- Timing: Apply prophylactic sprays (before disease appears) at the 3-5 leaf stage in grapes. If rain occurs, apply within 24-48 hours for curative action.
- Coverage: Ensure the spray reaches the underside of the leaves where Downy Mildew spores hide. High water volume is key.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not wash spray equipment in ponds.
Frequently Asked Questions
1. Is Kizuna fully systemic like Metalaxyl?
It is "translaminar" and "locally systemic." It moves across the leaf surface and penetrates inside to the other side, but it does not travel from roots to leaves. This makes it highly effective for leaf infections.
2. Can I mix Kizuna with other fungicides?
Yes. It is recommended to tank-mix Kizuna with contact fungicides like Mancozeb or Chlorothalonil. This improves efficacy and helps prevent resistance.
3. What if it rains after spraying?
Kizuna is rainfast within 2 to 3 hours. If it rains after this period, you do not need to respray immediately.
4. How does it help with Potato Late Blight?
It protects the leaves from rotting and prevents spores from washing down into the soil, protecting the potato tubers from infection and storage rot.
5. Why choose IFFCO-MC's Kizuna?
You get Japanese quality assurance (Mitsubishi Corp) combined with IFFCO's fair pricing and transparent distribution network.
