Item description
Flock Fungicide (Tricyclazole 75% WP): The Ultimate Rice Blast Solution
Secure your paddy yield with the "Gold Standard" in blast management.
Flock (by Nichino India) is a premium systemic fungicide designed specifically to fight the devastating Rice Blast disease. Unlike ordinary sprays, Flock works by stopping the fungus before it can even enter the plant.
Best For: Farmers looking for a preventive cure for Leaf Blast, Neck Blast, and Panicle Blast while improving grain quality and shine.
Why Choose Flock? Key Benefits
- ⏱️ Stops Disease Immediately: Prevents the fungus from penetrating the leaf surface, effectively neutralizing the threat before damage occurs.
- ?️ Complete Systemic Protection: Absorbed by roots and leaves, it moves upwards (acropetally) to protect new growth and critical leaf tips.
- ⏳ Long-Lasting Results: Provides reliable protection for 14+ days, reducing the need for frequent re-spraying.
- ?️ Rainfast in 1 Hour: Rapidly absorbed into the plant system, making it perfect for use during the rainy monsoon season.
- ? "Green Effect" Bonus: Improves crop vigor, leading to shiny, heavy grains and higher milling recovery (less chaff).

How It Works: Mode of Action
Flock is a Melanin Biosynthesis Inhibitor (MBI). It acts as an "Anti-Penetrant," protecting the plant like a shield.
- Blocks Melanin: It inhibits the enzyme reductase, preventing the fungus from producing melanin in its attack cell (appressorium).
- Stops Pressure Build-up: Without melanin, the fungus cannot generate the hydraulic pressure needed to punch through the tough rice leaf surface.
- Starves the Fungus: Unable to penetrate the plant to feed, the fungus dies on the surface, keeping your crop safe.
Note: Because it stops entry, it is most effective when applied before severe disease sets in.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Paddy (Rice) | Leaf Blast (All stages) |
| Paddy (Rice) | Node Blast |
| Paddy (Rice) | Neck Blast (Rotten Neck) & Panicle Blast |
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) |
|---|---|---|---|---|
| Paddy (Preventive) | 120 g | 200 L | 0.6 g | 21 - 30 |
| Paddy (Curative / High Risk) | 160 g | 200 L | 0.8 g | 21 - 30 |
| Nursery Drench | - | 15 L (Tank) | 12g / Pump | - |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing (Neck Blast): Apply at Late Booting / Early Heading (before panicles fully emerge) for best results. If the neck is already rotten, it is too late.
- Mixing: Flock is a Wettable Powder. Mix the required quantity in a small amount of water first to make a slurry, then add to the main tank. Keep agitated.
- Coverage: Use 200 Liters of water per acre. Good coverage of the leaf sheath and emerging panicle is critical.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid inhaling the dust during mixing.
Frequently Asked Questions
1. Can I use Flock on Basmati Rice for Export to the
EU?
No. The European Union has very
strict residue limits (0.01 ppm) for Tricyclazole. Do not
use Flock if the crop is destined for Europe. It is safe for
the US and domestic markets.
2. Does Flock cure the disease if the neck is already
broken?
No. Once the neck is rotten
(brown/black), the damage is done. Flock works best as a
preventive measure sprayed during the
booting stage to stop the rot from happening.
3. Is it safe to use during the rainy season?
Yes. Flock is rainfast within 1 to 2 hours. Once
absorbed, it cannot be washed off by rain.
4. Why does my crop look greener after spraying
Flock?
Flock has a
"phytotonic" effect. It reduces stress on the
plant and improves photosynthesis, leading to greener leaves
and heavier, shiny grains.
5. Can I mix Flock with other chemicals?
Flock is generally compatible with most insecticides.
However, always perform a small physical compatibility test before
mixing large tank quantities.
