- ⏱️Perfect Application Window: Ideal for "Early Post-Emergence" application (20-25 days after sowing), catching weeds at the vulnerable 2-4 leaf stage.
- ?️Double Action Safety: Offers systemic control that kills existing weeds while providing residual soil action to check late-emerging flushes.
- ⏳Cost-Effective Labor Saver: Provides a 4x-5x cost advantage over manual weeding, solving labor shortage issues during peak season.
- ?️Systemic Absorption: Rapidly absorbed by roots and leaves, making it effective even if light rains occur a few hours after application.
- ?Broad Spectrum Control: A single spray controls a wide variety of enemies: Grassy weeds, Broadleaf weeds, and difficult Sedges.

How It Works: Mode of Action
Fervent works by targeting the specific enzymes that weeds need to grow, while your pulse crops naturally detoxify the chemical.
- Absorption: The herbicide is quickly taken up by the weed's leaves and roots.
- Translocation: It moves through the plant's system to the active growing points (meristems).
- Inhibition: It blocks the ALS enzyme, stopping the production of essential amino acids (Valine, Leucine, Isoleucine), causing the weed to stop growing and eventually die.
Note: Visible symptoms like yellowing (chlorosis) and reddening typically appear 7-14 days after spraying.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|

| Groundnut | Digera arvensis, Euphorbia, Cyperus (Sedges) |
| Black/Green Gram | Mixed broadleaf and grassy flora |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Using less water than recommended leads to poor weed control.
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 - 2.5 ml | 90 |
| Groundnut | 400 - 600 ml | 200 - 240 L | 2 - 2.5 ml | 90 |
| Black / Green Gram | 250 - 300 ml | 150 - 200 L | 1.5 - 2 ml | 70 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Spray when weeds are at the 2-4 leaf stage (usually 20-25 days after sowing). If weeds are larger (6+ leaves), efficacy drops significantly.
- Mixing: Use a Flat Fan or Flood Jet nozzle for uniform coverage. Do not use muddy water for mixing.
- Coverage: Ensure sufficient soil moisture before spraying. Do not spray if the soil is cracked or extremely dry.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I plant Mustard immediately after harvesting Soybean treated with Fervent?
No. Mustard is highly sensitive to Imazethapyr residues. It is recommended to wait at least 18-24 months or perform a soil bioassay test before planting Mustard. Wheat or Chickpea are safer rotation options.
2. What happens if it rains after spraying?
Fervent is rainfast within 2-4 hours. Because it is systemic, once it is absorbed by the leaves, rain will not wash it off.
3. Can I mix Fervent with other herbicides?
It is generally compatible with certain insecticides, but mixing with other herbicides (especially for grasses) can sometimes reduce efficacy. Follow the specific advice of your local agronomist or Gromor expert.
4. Why are the weeds not dying immediately?
Fervent works by stopping growth first. Weeds stop competing for food immediately, but visible yellowing and drying may take 1 to 2 weeks. Be patient; the weeds are effectively neutralized.
5. Is it safe for the operator?
It is classified as "Slightly Hazardous" (Blue Triangle). While safer than many older chemicals, you must avoid skin contact and inhalation by wearing protective gear.
