Sayaka Fungicide (Picoxystrobin 7.05% + Propiconazole 11.71% SC)
The Ultimate "Shield & Sword" Protection for Rice, Wheat, and Vegetables.
Sayaka is a premium, broad-spectrum fungicide brought to you by IFFCO-MC. It combines two powerful chemistries to offer a "double-lock" defense against stubborn fungal diseases. It acts as a shield to prevent infection and a sword to cure existing diseases, ensuring your crops stay green, healthy, and high-yielding.
Best For: Farmers dealing with Sheath Blight in Paddy, Yellow Rust in Wheat, or Blights in vegetables who want superior coverage even in dense crops.
Why Choose This Product? Key Benefits
-
⏱️
Dual Action Power: Combines Picoxystrobin (Preventive) and Propiconazole (Curative) to stop disease spores on the surface and kill fungus already inside the plant.
-
🛡️
Unique "Vapor Action": Unlike ordinary fungicides, Sayaka releases a vapor that reaches hidden parts of the plant (like the lower stem in thick rice fields), ensuring 100% coverage.
-
⏳
The "Greening Effect": It boosts nitrogen absorption and delays plant aging. This keeps leaves greener for longer, directly resulting in heavier grains and higher yields.
-
🌧️
Excellent Rainfastness: Absorbs quickly into the plant system. It becomes rainproof within 2 to 4 hours, making it perfect for monsoon application.
-
🌿
Crop Safe Formulation: As a water-based Suspension Concentrate (SC), it is safer for crops than oil-based formulas, preventing leaf burn even in hot weather.

How It Works: Mode of Action
Sayaka operates via a "Shield and Sword" mechanism to manage resistance and ensure total control.
- Energy Blockade (Preventive): Picoxystrobin stops the fungus from producing energy (ATP) in its mitochondria. This instantly stops spores from germinating and penetrating the leaf.
- Cell Wall Destruction (Curative): Propiconazole stops the production of Ergosterol, a vital component of fungal cell walls. This causes the cell membrane to collapse, killing the fungus that has already entered the plant.
- Hyper-Systemic Movement: The chemical moves upward within the plant leaf (xylem mobile) and creates a vapor phase to redistribute itself to untreated areas, protecting new growth and lower stems.
This multi-site attack makes it very difficult for diseases to develop resistance against Sayaka compared to single-molecule fungicides.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Rice (Paddy) | Sheath Blight, False Smut, Dirty Panicle |
| Wheat | Yellow Rust (Stripe Rust), Leaf Rust |
| Chilli & Vegetables | Fruit Rot, Powdery Mildew, Early Blight (Tomato/Potato) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Water volume is critical for effectiveness.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice (Paddy) | 300 - 400 ml | 320 L | 1 - 1.25 ml | 24 - 30 |
| Wheat | 300 - 400 ml | 200 L | 1.5 - 2 ml | 35 |
| Chilli / Veg | 240 - 300 ml | 200 L | 1.2 - 1.5 ml | 5 - 7 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: For Rice and Wheat, apply preventively at the "Booting to Heading" stage. If disease is seen (e.g., 1-2 Sheath Blight lesions), spray immediately.
- Mixing: Ensure spray water pH is between 5.5 and 7.0. Avoid mixing with highly alkaline products like Bordeaux mixture.
- Coverage: Use high water volume (320 Liters/Acre for Rice) to ensure the medicine runs down to the stem base where Rhizoctonia hides.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not drain treated water into fish ponds.
Frequently Asked Questions
1. Does Sayaka cure Sheath Blight if the disease has already started?
Yes. Because it contains Propiconazole, it has strong curative action to stop lesion expansion. However, for best results, spray as soon as you see the first symptoms.
2. Can I mix Sayaka with insecticides for stem borer?
Yes, Sayaka is compatible with common insecticides like Chlorantraniliprole (Ferterra/Coragen) or Flubendiamide. This saves you labor costs.
3. How does the "Vapor Action" help me?
In thick crops like paddy, sprays often don't reach the bottom stems. Sayaka releases a gas (vapor) that moves through the canopy to protect these hard-to-reach areas.
4. Will this product burn my crops in hot weather?
No. Sayaka is a Suspension Concentrate (SC) formulation. It is water-based and solvent-free, making it much safer and less likely to cause phytotoxicity (burn) than older EC formulations.
5. How many times can I use Sayaka in one season?
Do not use it more than twice per season. This helps prevent the fungus from developing resistance to the chemical. Rotate with a different type of fungicide if needed.
