HerbicidesTokachi Herbicide (Penoxsulam) – Expert Guide for Rice
The Japanese-technology solution for "hard-to-kill" weeds in Paddy.
Note on Concentration: You searched for "2.7% SC," but Tokachi is primarily available as 2.5% OD (Oil Dispersion) or 21.7% SC. The "2.7%" is likely a typo for the 2.5% OD formulation. This guide focuses on the benefits of the Penoxsulam molecule used in these IFFCO-MC products.
Tokachi is a broad-spectrum, post-emergence herbicide designed for transplanted and Direct Seeded Rice (DSR). It effectively eliminates grasses, sedges, and broadleaf weeds in a single spray, ensuring your crop gets all the nutrition it needs without competition.

8 topicsWhy farmers choose itWhy Choose This Product? Key Benefits
- ⏱️ Stops Weed Growth Instantly: While visual death takes time, the weeds stop growing and competing for fertilizer within 48 hours of spraying.
- ?️ Excellent Crop Safety: Advanced selectivity ensures your rice plants (Paddy) remain healthy while the weeds are targeted.
- ⏳ Systemic Root Kill: The herbicide travels down to the roots and tubers, preventing tough weeds like Sedges from regrowing.
- ?️ Rainfast OD Technology: The Oil Dispersion (OD) formulation sticks to leaves better, offering resistance to wash-off from rain shortly after application.
- ? Broad Spectrum Control: A "One-Shot" solution that kills Grasses (like Barnyard grass), Sedges, and Broadleaf weeds simultaneously.

Product scienceHow It Works: Mode of Action
Tokachi works by starving the weed of essential amino acids required for life.
- Systemic Absorption: The herbicide is absorbed through both leaves and roots, moving rapidly throughout the plant via the xylem and phloem.
- Enzyme Blockade: It targets the ALS enzyme, which acts as a factory for creating vital proteins (Valine, Leucine, Isoleucine).
- Slow Death: Without these proteins, cell division stops. The weed stops growing immediately, turns yellow (chlorosis) in 7 days, and dies completely in 2-3 weeks.
Rice plants are safe because they contain natural enzymes that break down Penoxsulam before it can hurt them.

How to applyDosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
⚠️ IMPORTANT: The dosage below is for the 2.5% OD formulation (closest to your "2.7%" query). If you have the 21.7% SC bottle, the dose is much lower (approx 36-40ml/acre). Check your bottle label!
How to applyDosage per Acre (For Tokachi 2.5% OD)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice (Transplanted) | 350 - 400 ml | 120 - 150 L | ~ 2.5 ml | 60 |
| Direct Seeded Rice (DSR) | 350 - 400 ml | 120 - 150 L | ~ 2.5 ml | 60 |
| (If using 21.7% SC Formulation) | 36 - 40 ml | 120 - 150 L | 0.3 ml | 60 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
Useful detailsHow to Apply: Best Practices

- Timing: Apply when weeds are young (2 to 4 leaf stage), usually 10-15 days after transplanting or sowing. Do not delay beyond the 5-leaf stage.
- Water Management: Drain the water from the field before spraying so the chemical hits the weeds. Re-flood the field 48-72 hours after spraying and maintain water for 5-7 days.
- Coverage: Use a Flat Fan or Flood Jet nozzle on your knapsack sprayer for even coverage. Avoid drift to nearby non-paddy crops.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.

Frequently Asked Questions
1. I found "2.7% SC" online, is that correct?
This is likely a typo. The standard formulations are 2.5% OD (Oil Dispersion) or 21.7% SC. Always read the active ingredient percentage on your bottle to calculate the correct dose.
2. Can I mix Tokachi with insecticides?
Avoid mixing with Organophosphate insecticides (like Chlorpyrifos) as it may hurt the rice plants. Wait 7-10 days between herbicide and insecticide sprays.
3. How quickly will I see results?
Weeds stop growing immediately, but visible browning takes 1-2 weeks. Do not panic if weeds stay green for a few days; they are already effectively dead.
4. Does it work on large weeds?
Efficiency drops significantly on mature weeds (older than 5 leaves). It is best used on young, actively growing weeds.
5. What is the benefit of the IFFCO-MC brand?
Tokachi comes with "Kisan Suraksha Bima Yojana"—a free accidental insurance cover for farmers, ensuring both crop and personal safety.
