Furusato Herbicide (Oxyfluorfen 23.5% EC): Complete Guide
Furusato is a premium broad-spectrum herbicide brought to you by IFFCO-MC (a joint venture with Mitsubishi, Japan). It is designed to keep your Onion, Tea, and Rice fields weed-free using advanced Japanese technology.
Powered by the active ingredient Oxyfluorfen (23.5% w/w), Furusato acts as a chemical barrier on the soil surface. It attacks weeds at the germination stage and burns down young weeds upon contact with sunlight. It is the ideal labor-saving solution for modern Indian farming, replacing expensive manual weeding.
Why Choose This Product? Key Benefits
-
⏱️
Dual Action Power: Works as both a Pre-emergence (stops seeds) and early Post-emergence (burns young weeds) herbicide.
-
🛡️
The Chemical Barrier: Forms a protective layer on the soil surface that kills weeds as they try to emerge.
-
⏳
Long-Lasting Control: Provides residual weed control for 30–40 days, protecting the crop during its critical growth period.
-
🌧️
Rainfast & Stable: Binds tightly to soil particles. It does not leach into groundwater or wash away easily once settled.
-
🌿
High Return on Investment: One spray costs a fraction of manual weeding labor, saving you up to ₹5,000–₹10,000 per hectare.

How It Works: Mode of Action
Furusato creates a "chemical veil" on the soil. It works through a unique light-activated process.
- Contact & Absorption: When weed seedlings sprout and touch the treated soil layer, they absorb the chemical.
- Light Activation: The absorbed chemical reacts with sunlight to produce reactive oxygen inside the plant cells.
- Rapid Desiccation: This reaction destroys the cell membranes, causing the weed to dry out and die within hours of sunlight exposure.
Note: Because it needs light to work, you may not see results immediately if sprayed in the dark until the sun rises.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Onion | Chenopodium (Bathua), Amaranthus (Chaulai), and other broadleaf weeds. |
| Tea | Imperata cylindrica, Digitaria, and broadleaf complexes. |
| Rice, Potato, Groundnut | Echinochloa (Barnyard grass), Cyperus (Motha/Sedges), and broadleaves. |
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) |
|---|---|---|---|---|
| Onion | 170 – 340 ml | 200 – 300 L | 1.5 – 2.0 ml | 7 |
| Tea | 260 – 400 ml | 200 – 300 L | 2.0 – 2.5 ml | 15 |
| Rice / Potato / Groundnut | 260 – 400 ml | 200 L | 2.0 ml | -- |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: For most crops (Potato, Groundnut, Direct Rice), apply within 0–3 days of sowing (Pre-Emergence). For Onions, apply just before transplanting or after the 3-4 leaf stage (never earlier).
- Mixing: Mix well. Do not use if the soil is bone dry; ensure some soil moisture for the chemical to bind.
- Coverage: Use Flat Fan or Flood Jet nozzles only. Avoid Hollow Cone nozzles as fine mist causes drift and damage.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Is Furusato an EC or SC formulation?
The official registered Furusato product is a 23.5% EC (Emulsifiable Concentrate). While some retailers label it SC, the EC formulation provides powerful solvent-based penetration.
2. Can I spray this on standing Onion crops?
Yes, but be careful. Do not spray on very young onions (1-2 leaves). Wait until the onion has 3-4 leaves to avoid twisting and burning.
3. Will it affect the next crop?
No. Furusato degrades in the soil within 30-40 days. It does not carry over to damage rotational crops like wheat or sunflower.
4. Why did my Onion tips turn white after spraying?
This is "contact burn" and is common. Because Onions are waxy, the damage is superficial. The crop usually recovers fully within a few weeks without yield loss.
5. Can I use it for Potato after shoots appear?
No! For Potato, it must be sprayed strictly pre-emergence (before shoots crack the soil). Spraying on green potato leaves will cause severe damage.
