How It Works: Mode of Action
[Image of herbicide enzyme inhibition mechanism] HPM Dhavak works via Contact Action. It must be sprayed directly onto the green parts of the weed.
- Absorption: The active ingredient is absorbed by the plant leaves.
- Enzyme Block: It inhibits the 'Glutamine Synthetase' enzyme, which is vital for plant metabolism.
- Cellular Collapse: This blockage causes toxic ammonia to build up inside the plant cells, destroying them and killing the weed quickly.
Result: Rapid yellowing and drying of weeds within a few days.

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 Litres | 5 - 6 ml | Refer Leaflet |
| Tea | 1000 - 1300 ml | 200 Litres | 5 - 6.5 ml | Refer Leaflet |
| Non-Crop | 1200 ml | 200 Litres | 6 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 when weeds are actively growing (2-4 leaf stage) for maximum absorption.
- Mixing: Use clean water. Avoid muddy water as it can reduce efficacy.
- Coverage: Use a flat fan or flood jet nozzle. Ensure complete wetting of weed foliage as this is a contact herbicide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. How quickly will I see results?
Dhavak is known for its speed. You will typically see yellowing and withering of weeds within 3 to 5 days of application.
2. Is Dhavak safe for my main crop?
Since it is non-selective, it will kill any green plant it touches. Use a protective hood/shield when spraying in Cotton to avoid contact with the crop leaves.
3. Can I use it if it is cloudy?
Yes! Unlike many other herbicides, Dhavak remains highly effective even in low sunlight or cloudy weather.
4. Does it harm the soil?
No. Glufosinate Ammonium breaks down rapidly in the soil, leaving no harmful residues for the next season.
5. What weeds does it kill?
It is a broad-spectrum killer, effective against annual grasses, broad-leaf weeds, and difficult sedges.
