Yugata Bispyribac Sodium 10% SC (Marketed as EC Replacement)
The "Gold Standard" Post-Emergent Herbicide for Weed-Free Rice Farming.
Yugata by IFFCO-MC is a broad-spectrum systemic herbicide designed specifically for paddy fields. It eliminates the toughest grasses, sedges, and broadleaf weeds that steal nutrition from your rice crop.
Note on Formulation: While you may be searching for "10% EC," Yugata is formulated as a Suspension Concentrate (SC). This modern "SC" technology is safer for your crop, reduces leaf burn, and provides better absorption than older EC liquids. It is the superior choice for modern farming.
Why Choose This Product? Key Benefits
-
⏱️
Stops Growth Instantly: Absorbed by weeds within 6 hours. It immediately halts the production of essential amino acids, stopping weed competition instantly.
-
🛡️
Japanese Technology & Safety: Developed with Mitsubishi Corporation expertise. The SC formulation is water-based, minimizing crop shock compared to solvent-based ECs.
-
⏳
Wide Application Window: Perfect for "rescue" treatment. It works effectively even when weeds have reached the 2 to 5-leaf stage.
-
🌧️
Complete Systemic Action: Moves from the leaves down to the roots and up to the shoot, ensuring the weed is killed completely and does not regrow.
-
🌿
All-in-One Solution: Controls a mixed population of weeds (Grasses, Sedges, and Broadleaf) with a single spray, saving you labor costs.

How It Works: Mode of Action
Yugata works by starving the weed of the proteins it needs to survive.
- Uptake: The herbicide is absorbed through the leaves and roots, moving rapidly to the growing points of the weed.
- Inhibition: It blocks the ALS enzyme, which is responsible for creating essential amino acids (Valine, Leucine, Isoleucine).
- Elimination: Without these building blocks, the weed stops growing immediately, turns yellow, and dies within 7-14 days.
Smart Selectivity: Your rice crop naturally contains an enzyme that breaks down Yugata rapidly, ensuring the crop remains safe while the weeds die.

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 (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Paddy (Rice) | 80 ml - 120 ml | 120 - 150 Litres | 0.6 - 1.0 ml | Refer to Label |
| Nursery | 10 - 12 ml per pump | As required | 1.0 ml | - |
| Direct Seeded | 80 ml - 120 ml | 120 - 150 Litres | 0.6 - 1.0 ml | Refer to Label |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Spray when weeds are actively growing and have 2 to 5 leaves. (Usually 10-14 days after transplanting).
- Mixing: Use the "Drain - Spray - Flood" method. Drain the water from the field before spraying so the medicine hits the weeds directly.
- Coverage: Use a Flat Fan or Flood Jet nozzle for uniform coverage. Re-flood the field 24-48 hours after spraying to suppress new weeds.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. My paddy turned slightly yellow after spraying. Is this normal?
Yes, this is a temporary "Yellow Flash." It happens because the plant is metabolizing the herbicide. The crop will recover its green color within 5-7 days and will yield better because the weeds are gone.
2. Can I mix Yugata with Urea?
Yes! Mixing 1-2% Urea in the spray tank helps break down the waxy coating on weed leaves, increasing the effectiveness of the herbicide.
3. Is Yugata an EC or SC formulation?
Yugata is an SC (Suspension Concentrate). SC is an upgrade over EC; it is water-based, eco-friendly, and poses less risk of burning your crop compared to oil-based ECs.
4. What nozzle should I use?
Always use a Cut/Flood Jet or Flat Fan nozzle. Avoid using the fine mist hollow cone nozzle used for insecticides, as it causes drift.
5. Can I mix it with insecticides?
It is compatible with common insecticides like Imidacloprid or Fipronil (Shinzen). However, avoid mixing with Flubendiamide as it may reduce weed control.
