Syngenta Fusiflex Herbicide: Complete Usage Guide & Price
Expert Note: Confusion Alert!
Many websites mistakenly list Fusiflex as an "Insecticide" (for killing bugs). This is incorrect. Fusiflex is a specialized Herbicide (weed killer) designed to protect Soybean and Groundnut crops from unwanted grass and broadleaf weeds. Using it as an insecticide could damage your crop.
Fusiflex combines two powerful chemicals to give you a "double-action" punch against stubborn weeds, saving you money on manual labor.
Why Choose This Product? Key Benefits
- ⏱️Fast Action:
Weeds stop growing within 48 hours. You will see them turning yellow and drying up quickly. - ?️Double Protection:
It targets both thin grasses (monocots) and broadleaf weeds (dicots) in a single spray. - ⏳Cost Effective:
One bottle can do the work of 8-10 laborers, saving you over 60% on weeding costs. - ?️Rainfast:
The chemical is absorbed quickly. If it rains 1-2 hours after spraying, the medicine will still work. - ?Crop Safety:
Specially formulated to be tough on weeds but safe for Soybean and Groundnut plants when used at the right dose.

How It Works: Mode of Action
Fusiflex uses a "Double-Tap" strategy to ensure weeds cannot survive:
- Systemic Attack (Fluazifop): Absorbed by leaves and moves to the roots. It stops the production of fats (lipids), causing grass weeds to rot from the growing point.
- Contact Burn (Fomesafen): Acts like a "sunburn" for weeds. It breaks down cell membranes in broadleaf weeds, causing them to dry out and die rapidly upon exposure to sunlight.
- Selective Safety: While it destroys weeds, your Soybean and Groundnut plants have special enzymes that break down the chemical, keeping them safe.
Note: You might see slight temporary speckling on crop leaves, but the plants recover quickly.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Soybean | Barnyard Grass (Sawan), Jungle Rice, Commelina (Kena), Digera (Lahsua), Lovegrass. |
| Groundnut (Peanut) | Crabgrass, Crowfoot Grass, Horse Purslane (Santhi), Carrot Grass (Parthenium), False Amaranth. |
| Cotton (Caution*) | *Use only if specifically recommended by a local agronomist. Primary use is Legumes. |
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) |
|---|---|---|---|---|
| Soybean | 400 - 500 ml | 200 Litres | 2 - 2.5 ml | 14 Days |
| Groundnut | 400 - 500 ml | 200 Litres | 2 - 2.5 ml | 56 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note the long wait time for Groundnut!
How to Apply: Best Practices
- Timing: Spray when weeds are at the 3-4 leaf stage. Spraying too late (when weeds are big) will result in poor control.
- Mixing: Use a minimum of 200 Litres of water per acre. This product acts partly by contact, so good coverage of the leaves is essential. Do not use low-volume drone sprays for this product.
- Coverage: Ensure the nozzle creates a fine mist to cover the weed foliage completely.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Is Fusiflex an Insecticide?
No. This is a common internet error. Fusiflex is a herbicide for weeds. For insects (caterpillars), you need products like Ampligo or Fame, not Fusiflex.
2. When should I spray Fusiflex?
The best time is 15-20 days after sowing, or strictly when the weeds have 3 to 4 leaves.
3. Can I mix it with other chemicals?
It is best applied alone. Mixing with other insecticides or fungicides might reduce its effectiveness or burn the crop.
4. What is the price of Syngenta Fusiflex?
Prices vary by dealer, but generally: 250ml is ₹550-600, 400ml is ₹850-950, and 1 Litre is around ₹1,900-2,000.
5. Will it kill my crop?
If used on Soybean or Groundnut at the correct dose, it is safe. Do not use on crops like Maize or Rice as it will kill them.
