Milquat Herbicide (Paraquat Dichloride 24% SL) by IIL
Fast-Acting "Contact" Weed Killer for Total Weed Control & Crop Desiccation
Milquat (manufactured by Insecticides India Ltd.) is a powerful, non-selective contact herbicide. It is designed to burn down green plant tissue on contact, making it an excellent choice for clearing weeds in plantation crops, "chemical hoeing," and preparing fields for zero-tillage farming. Unlike systemic weed killers that take weeks, Milquat works within hours.
Important Safety Note: Milquat is a Restricted Use Pesticide. It is highly effective but toxic if mishandled. Always use protective gear and never transfer to food/drink containers.
Why Choose This Product? Key Benefits
- ⏱️Rapid Action: Visible drying of weeds occurs within hours. Complete kill often happens within 24–48 hours in bright sunlight.
- ?️Soil Safety (Zero Residual): Milquat becomes biologically inactive immediately upon touching the soil. It does not harm the roots of the next crop, allowing for immediate sowing.
- ⏳Rainfastness: Absorbs into the leaf quickly. It remains effective even if it rains just 15–30 minutes after spraying.
- ?️Versatile Use: Ideal for inter-row weeding in Tea, Coffee, and Rubber, as well as pre-planting burndown for Rice, Wheat, and Maize.
- ?Cost-Effective: Provides total weed control at a fraction of the cost of manual labor or expensive glufosinate-based alternatives.

How It Works: Mode of Action
Milquat is a unique "hijacker" of the plant's energy system. It requires sunlight to work effectively.
- Penetration: The spray droplets land on the green foliage and penetrate the leaf surface almost instantly.
- Energy Interception: Inside the plant cells (chloroplasts), Milquat steals electrons from photosynthesis, converting them into destructive "superoxide radicals."
- Cell Destruction: These radicals destroy the cell membranes, causing the plant cells to leak and dry out rapidly. This results in quick browning and death of the weed.
Note: Since it destroys cells on contact, it does not travel to the roots. Perennial weeds may regrow and require a second spray.
Target Crops & Pests
| Crop | Target Application |
|---|---|
| Tea, Coffee, Rubber | Control of grassy and broadleaf weeds in inter-rows; ferns and shade-loving weeds. |
| Cotton | Inter-row weed control (with hood) and as a defoliant (Harvest Aid) to clean fields before picking. |
| Rice, Wheat, Maize | Pre-plant burndown (Zero Tillage) to clear field before sowing seeds; Stale seedbed method. |
| Potato | Haulm destruction (drying vines) before harvest to harden skin. |
| Aquatic Areas | Control of Water Hyacinth and other floating weeds (non-potable water only). |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Unlike systemic herbicides, high water volume is critical for coverage.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop / Use | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Tea / Coffee | 500 - 1000 ml | 200 L | 2.5 - 5 ml | - |
| Rice / Wheat / Maize | 500 - 1000 ml | 200 L | 2.5 - 5 ml | Pre-Sowing |
| Potato (Haulm) | 500 - 800 ml | 200 L | 2.5 - 4 ml | Harvest Aid |
| Cotton | 500 - 800 ml | 200 L | 2.5 - 4 ml | Harvest Aid |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply when weeds are young (2-3 leaf stage) and actively growing. Spray in bright sunlight for fastest results.
- Mixing: Use ONLY clean water. Muddy or dirty water deactivates the chemical immediately.
- Coverage: Use Flat Fan or Flood Jet nozzles. Ensure thorough wetting of the foliage. Do not use mist blowers to avoid inhaling fine droplets.
- Safety: Always wear PPE (gloves, mask, goggles, boots). Wash hands thoroughly after use. Do not walk through the treated area until dry.
Frequently Asked Questions
1. Does Milquat kill the roots of the weeds?
No. Milquat is a contact herbicide. It kills the green parts above the ground. Deep-rooted perennial weeds may regrow and require a follow-up spray.
2. Can I sow seeds immediately after spraying?
Yes. Milquat is inactivated instantly upon contact with soil/clay. It leaves no active residue, making it safe to sow crops like wheat or rice the very next day.
3. How does it compare to Glyphosate?
Glyphosate is systemic (kills roots) but takes 7-10 days to work. Milquat is contact-based and works in 24-48 hours. Milquat is better for "quick fixes" and erosion control.
4. What happens if it rains after spraying?
Milquat is rainfast within 15-30 minutes. Once it penetrates the leaf, rain will not wash it off or reduce its efficacy.
5. Why is the liquid blue and smelly?
These are safety additives. The blue dye prevents it from looking like water, and the "stenching agent" (foul smell) is added to prevent accidental ingestion.
