Paraforce Herbicide (Paraquat Dichloride 24% SL) by Nichino India
The fast-acting "Burn-Down" herbicide for plantation and row crops.
Paraforce is a broad-spectrum, non-selective contact herbicide containing Paraquat Dichloride 24% SL. It is widely recognized in Indian agriculture for its ability to destroy weeds within hours of application. Unlike systemic weed killers that take weeks, Paraforce works on contact, making it an essential tool for "chemical mowing" in tea, coffee, and rubber estates.
Important: While highly effective for conservation agriculture and no-till farming, this product is toxic. It requires strict adherence to safety protocols and dosage instructions.
Why Choose This Product? Key Benefits
- ⏱️Rapid Action: Visible results appear within 2–4 hours. It is one of the fastest ways to clear vegetation.
- ?️Soil Safety: Upon contact with soil, the chemical becomes biologically inactive. You can plant your next crop almost immediately after spraying.
- ⏳Rainfastness: Absorbs into the leaf within 15–30 minutes. Sudden monsoon rains will not wash it away or reduce efficacy.
- ?️Weather Resistant: Ideal for use during the rainy season (monsoon) when manual weeding is difficult or impossible.
- ?Cost-Effective: A significantly cheaper alternative to manual weeding labor, costing roughly ₹800/acre vs ₹3000+/acre for manual labor.

How It Works: Mode of Action
Paraforce acts as a "Photosystem I Electron Diverter." It turns the plant's own energy against itself to cause rapid drying.
- Absorption: The liquid penetrates the green leaf cuticle within minutes of spraying.
- Disruption: It intercepts electrons during photosynthesis (Redox Cycling), creating destructive "superoxide radicals."
- Desiccation: These radicals rupture cell membranes, causing the plant tissue to dry out and die within 48 hours.
Note: It does not kill the roots (non-systemic), so it is best for annual weeds or controlling top growth.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Plantation Crops (Tea, Coffee, Rubber) | Imperata cylindrica, Commelina, Setaria, Borreria (Grasses & Broadleaves) |
| Field Crops (Cotton, Rice, Maize) | Barnyard grass, Nutgrass, Chenopodium (Pre-plant or Inter-row with Hood) |
| Fruit Orchards (Apple, Grapes, Citrus) | Bindweed, Portulaca, Tridax (Orchard floor weed management) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Paraforce requires high water volume for thorough coverage.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Tea / Coffee | 400 - 1200 ml | 200 - 250 L | ~4 - 6 ml | - |
| Cotton / Rice (Pre-plant) | 400 - 850 ml | 200 - 250 L | ~4 - 5 ml | - |
| Aquatic Weeds | 400 - 1700 ml | Depending on area | ~6 - 8 ml | - |
*Standard Knapsack Calculation: Approximately 80-100 ml per 15-litre tank.
How to Apply: Best Practices
- Timing: Apply when weeds are young and actively growing (2-4 leaf stage) for best results.
- Mixing: Use clean water. Avoid muddy water as soil particles can deactivate the herbicide immediately.
- Coverage: Use a flat fan or floodjet nozzle. If spraying between crop rows (e.g., Maize/Cotton), use a Protective Hood/Shield to prevent drift onto the crop.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not inhale the spray mist.
Frequently Asked Questions
1. Why is the liquid blue and smelly?
The blue dye and pungent "stenching agent" are mandatory safety additives to stop people from mistaking it for beverages like coffee or cola.
2. Does Paraforce kill the weed roots?
No. Paraforce is a contact herbicide. It kills the green parts above the ground but does not travel to the roots.
3. Can I use it in my vegetable garden?
It is generally not recommended for home vegetable gardens due to toxicity risks and drift. It is strictly for commercial agricultural use.
4. What if it rains after spraying?
Paraforce is "rainfast" within 15–30 minutes. Rain after this period will not reduce its effectiveness.
5. Is there an antidote for Paraforce?
No specific antidote exists. Immediate medical attention and gastric decontamination (within the first hour) are critical in case of accidental ingestion.
