HPM Dhavak Herbicide (Glufosinate Ammonium 13.5% SL)
The "Swift Runner" against stubborn weeds in Cotton and Tea plantations.
HPM Dhavak is a powerful, broad-spectrum contact herbicide designed for the modern farmer. True to its name (which means "Runner" or "Swift"), it delivers rapid knockdown of weeds that steal nutrition from your crops. Formulated with Glufosinate Ammonium 13.5% SL, it is the perfect solution for controlling hard-to-kill weeds while being gentler on your soil compared to older chemicals.
Best for: Farmers facing weed resistance issues in Cotton, Tea, and non-crop areas.

How It Works: Mode of Action
HPM Dhavak is a Contact Herbicide. This means it kills the parts of the plant it touches. It does not travel through the plant's roots, which makes it safer for inter-row application.
- Enzyme Inhibition: It stops the plant from using a vital enzyme called Glutamine Synthetase.
- Ammonia Build-up: Without this enzyme, the plant cannot process nitrogen correctly, leading to a toxic buildup of ammonia inside the plant cells.
- Rapid Collapse: This toxicity destroys the plant's cells and energy reserves, causing the weed to turn yellow and die quickly (Phytotoxicity).
Because it works differently than other common weedkillers, it is excellent for breaking the resistance cycle.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Grasses, Broadleaf weeds, Sedges |
| Tea Gardens | Grasses, Broadleaf weeds, Sedges |
| Non-Crop Areas | General Vegetation (Industrial sites, Railways, etc.) |
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) |
|---|---|---|---|---|
| Cotton | 1000 - 1200 ml | 200 L | 5 - 6 ml | As per Label |
| Tea | 1000 - 1200 ml | 200 L | 5 - 6 ml | As per Label |
| Non-Crop | 1 Litre | 200 L | 5 ml | - |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply "Post-Emergence," meaning spray after the weeds have sprouted. It works best on young, actively growing weeds.
- Mixing: Use clean water. Ensure the nozzle provides a fine spray for maximum contact with weed leaves.
- Coverage: Since this is a contact herbicide, ensure thorough coverage of the target vegetation. It will only kill what it touches.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying on windy days to prevent drift onto your main crop.
Frequently Asked Questions
1. Does Dhavak affect the main crop?
Dhavak is a non-selective herbicide, meaning it can damage any plant it touches. However, it is safe for crops like Cotton and Tea if used as an inter-row spray (spraying between the rows) carefully avoiding contact with the crop leaves.
2. Can I use this in cloudy weather?
Yes! One of Dhavak's biggest advantages is that it works effectively even in low sunlight or cloudy conditions, unlike some other herbicides that require bright sun.
3. How long does it take to see results?
Dhavak is known for its "swift" action. You will typically see weeds turning yellow and wilting very quickly after application due to its rapid knockdown effect.
4. Does it damage the soil?
No. Glufosinate Ammonium breaks down rapidly in the soil. It leaves very low residue, making it a safer choice for the environment and future planting compared to older, persistent chemicals.
5. What weeds does it kill?
It is a broad-spectrum killer. It controls grassy weeds, broadleaf weeds, and hard-to-kill sedges. It is especially useful for weeds that have become resistant to Glyphosate.
