Sokusai Plus (Pretilachlor 37% EW): Advanced Pre-Emergence Herbicide for Rice
The "Green Chemistry" Solution for Weed-Free Paddy Fields by IFFCO-MC.
Sokusai Plus is a premium pre-emergence herbicide designed specifically for transplanted rice. A result of the strategic alliance between IFFCO and Mitsubishi Corporation, this product brings Japanese precision to Indian farming. It contains Pretilachlor 37% EW, a specialized formulation that is tougher on weeds but safer for your crop and the environment compared to older chemical options.
Best For: Farmers looking for an economical, labor-saving alternative to manual weeding that protects yields right from the start.
Why Choose This Product? Key Benefits
- ⏱️Early Action: Kills weeds before they emerge, eliminating competition during the critical early crop stage.
- ?️Superior Safety (EW Technology): The water-based EW formulation is safer for the user and the rice plant than older oil-based (EC) sprays.
- ⏳Cost-Effective: Costs nearly 90% less than manual weeding labor, offering high economic returns.
- ?️Excellent in Standing Water: Specifically designed to spread uniformly in the standing water of paddy fields.
- ?Broad Spectrum: Controls grasses, sedges, and broad-leaved weeds simultaneously.

How It Works: Mode of Action
Sokusai Plus works by creating a chemical barrier on the soil surface. It targets weeds at the cellular level:
- Absorption: The herbicide is absorbed rapidly through the shoots (coleoptiles) of germinating grasses and the roots of broad-leaf weeds.
- Growth Stop: It inhibits the synthesis of Very Long Chain Fatty Acids (VLCFAs), which are essential for cell division.
- Elimination: Without cell division, the weed seedlings fail to grow and die before they can emerge above the water level.
Note: Transplanted rice is safe because its roots are below the treated soil layer and it has a physiological tolerance to the chemical.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Transplanted Rice (Paddy) | Grasses: Barnyard Grass (Echinochloa spp.), Jungle Rice, Chinese Sprangletop. |
| Sedges: Smallflower Umbrella Sedge, Rice Flatsedge (Cyperus spp.). | |
| Broad-Leaved Weeds: Pickerel Weed, False Daisy, Water Primrose. |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" and apply within 0-3 days of transplanting.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice (Light Soil) | 600 ml | 200 L | 3 ml | Season Long* |
| Rice (Heavy/Clay Soil) | 750 ml | 200 L | 3.75 ml | Season Long* |
*PHI: Since Sokusai Plus is applied at the very beginning of the season (Pre-emergence), it degrades safely before harvest.
How to Apply: Best Practices
- Timing: Apply strictly within 0 to 3 Days After Transplanting (DAT). Late application drastically reduces effectiveness.
- Mixing: Shake the bottle well. Mix the required dose with water (not sand/fertilizer) for spray application. Use a Flood Jet or Flat Fan nozzle for even distribution.
- Coverage: Ensure the field has 2-3 cm of standing water. Do not drain or irrigate for 2-3 days after application to allow the chemical barrier to set.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Why is the EW formulation better than the old EC?
EW (Emulsion in Water) is "Green Chemistry." It uses water as a base instead of petroleum solvents. This makes it safer for the farmer to handle, less likely to burn rice leaves, and friendlier to the soil ecosystem.
2. Can I apply Sokusai Plus after weeds have already appeared?
No. Sokusai Plus is a Pre-Emergence herbicide. It must be applied before weeds germinate (within 0-3 days of transplanting) to work effectively.
3. Do I need to remove water before spraying?
No. You need standing water (about 2-3 cm deep) in the field. The water helps spread the chemical evenly across the soil surface.
4. Is it safe for the next crop (like wheat)?
Yes. Sokusai Plus breaks down in the soil during the rice season and does not persist to damage rotation crops like wheat or mustard grown in the Rabi season.
5. Who manufactures Sokusai Plus?
It is manufactured by IFFCO-MC Crop Science Pvt. Ltd., a joint venture between the trusted Indian cooperative IFFCO and the Japanese conglomerate Mitsubishi Corporation.
