How It Works: Mode of Action
Fervent works by targeting a specific enzyme in weeds that is necessary for growth.
- Absorption: Upon spraying, the liquid is rapidly absorbed by the weed's leaves and roots.
- Translocation: The active ingredient travels through the plant to the growing points (meristems).
- Inhibition: It blocks the ALS enzyme, stopping the production of essential amino acids. The weed stops growing immediately and dies within 7 to 14 days.
Note: Legume crops naturally metabolize (break down) the chemical, keeping them safe while weeds perish.

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 - 600 ml | 200 - 240 L | 2.5 - 3 ml | 75 - 100 |
| Groundnut | 400 - 600 ml | 200 - 240 L | 2.5 - 3 ml | 90 - 100 |
| Black/Green Gram | 400 - 600 ml | 200 L | 2 - 3 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 strictly at the 2 to 4 leaf stage of weeds (Early Post-Emergence). Spraying on older weeds reduces effectiveness.
- Mixing: Dissolve the required quantity in a small amount of water first, then add it to the main tank. Use clean water.
- Coverage: Use a flat fan or flood jet nozzle. Ensure thorough coverage of weed leaves for absorption.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Which crops is Fervent suitable for?
It is primarily recommended for Soybean, Groundnut, Black Gram, and Green Gram.
2. When should I spray Fervent?
The best time is 20-25 days after sowing, specifically when weeds have 2 to 4 leaves.
3. Can I plant Mustard immediately after harvesting the treated crop?
No. Fervent has soil residues that can affect Mustard. It is safer to rotate with Chickpea (Gram) or Wheat.
4. Does it kill Motha (Cyperus rotundus)?
It suppresses the growth of Cyperus rotundus efficiently, allowing your crop canopy to cover the ground.
5. Is it rainfast?
Yes, since it is a systemic herbicide absorbed by the plant, it generally performs well if it doesn't rain immediately after spraying (give it a few hours to absorb).
