Sodatsu Fungicide (Cymoxanil 8% + Mancozeb 64% WP): The Ultimate Guide
Stop Late Blight and Downy Mildew in their tracks with the dual-power of Japanese technology.
Sodatsu is a specialized fungicide brought to you by IFFCO-MC (a joint venture with Mitsubishi Corporation). It combines two powerful chemistries to protect your Potato, Tomato, and Grape crops. It acts as a "companion" fungicide, meaning it cures existing infections while providing a strong protective shield against new attacks.
Best For: Farmers looking for a cost-effective, high-quality solution to manage tough diseases like Blight during the rainy season.
Why Choose This Product? Key Benefits
-
⏱️
Instant "Kick-Back" Action: Stops the disease even if the fungus has already entered the plant (up to 24-48 hours after infection).
-
🛡️
Double Shield Protection: Combines Contact action (outside the leaf) and Local Systemic action (inside the leaf) for total coverage.
-
⏳
Resistance Fighter: The multi-site action makes it very hard for fungi to develop resistance, keeping the medicine effective for years.
-
🌧️
Excellent Rainfastness: Absorbs quickly into the plant system, so it doesn't wash off easily if it rains shortly after spraying.
-
🌿
Greener Crops: Contains Zinc (Zn) and Manganese (Mn) which nourish the plant, making leaves greener and healthier.

How It Works: Mode of Action
Sodatsu uses a "Sandwich" strategy to trap the fungus from both the inside and outside.
[Image of Cymoxanil and Mancozeb mode of action diagram]- Rapid Penetration (Cymoxanil): Upon spraying, this component quickly enters the leaf tissue (within 3 hours). It finds the fungus that is incubating inside and stops its growth immediately.
- Surface Barrier (Mancozeb): This component stays on the leaf surface, forming a toxic layer. When new fungal spores land on the leaf, they are killed instantly on contact.
- Translaminar Movement: The medicine moves from the top of the leaf to the bottom, killing hidden pests on the underside of the leaves.
This combination prevents the "incubation" of the disease and stops spore production.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Potato & Tomato | Late Blight (Phytophthora infestans) |
| Grapes | Downy Mildew (Plasmopara viticola) |
| Cucumber / Melons | Downy Mildew |
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) |
|---|---|---|---|---|
| Potato / Tomato | 600 g | 200 - 300 L | 2.0 - 3.0 g | 7 - 14 |
| Grapes | 600 - 800 g | 300 - 400 L | 2.0 g | 60+ (Check Export Rules) |
| Cucumber | 600 g | 200 L | 2.0 - 2.5 g | 3 - 7 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply preventatively (before disease starts) or at the very first sign of disease. Repeat every 10–15 days. If weather is cloudy/wet, spray every 7 days.
- Mixing: Never dump the powder directly into the full tank. Mix the powder in a small bucket first to make a smooth "cream" (slurry), then add it to the main tank.
- Coverage: Use high water volume. Ensure the spray covers the underside of leaves where stomata are located.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can Sodatsu cure disease after it appears?
Yes, it has "kick-back" action. If applied within 24-48 hours of infection, it can stop the fungus from developing inside the leaf.
2. Is Sodatsu rainfast?
Yes, the Cymoxanil component penetrates the leaf quickly (within 3 hours), making it effective even if light rains occur shortly after spraying.
3. Can I mix Sodatsu with other chemicals?
It is generally compatible with common insecticides. However, do not mix with highly alkaline products like Bordeaux Mixture or Lime Sulphur, as this destroys the medicine.
4. Why is IFFCO-MC Sodatsu a good value choice?
IFFCO-MC focuses on selling at fair MRP without hidden dealer margins, offering Japanese quality formulation at a reasonable price for Indian farmers.
5. How many times can I spray it?
To prevent resistance, do not spray more than 4 consecutive times. Rotate with other fungicides like Dimethomorph or Strobilurins.
