HPM Hifit Plus Herbicide (Pretilachlor 37% EW)
The Ultimate Pre-Emergence Solution for Weed-Free Rice Farming
Hifit Plus is a specialized, broad-spectrum herbicide designed to protect your paddy fields during the most critical early stages of growth. Powered by advanced Pretilachlor 37% EW technology, it creates a powerful chemical barrier that stops weeds before they emerge.
Unlike older formulations, Hifit Plus uses an Emulsion in Water (EW) formula. This means it dissolves instantly, spreads uniformly across the water, and is safer for your crop—providing a distinct "Greening Effect" to rice seedlings without causing shock or yellowing.

How It Works: Mode of Action
Hifit Plus operates as a selective pre-emergence herbicide. It targets weeds at their most vulnerable stage—germination.
- Absorption: The active ingredient is rapidly absorbed by the hypocotyls and coleoptiles (emerging shoots) of the weeds.
- Inhibition: It acts as a VLCFA Inhibitor, blocking the synthesis of fatty acids required for cell growth.
- Termination: This stops cell division immediately, causing the weeds to die before they can break the soil surface or compete with your crop.
Note: Because it works on germination, it must be applied before weeds have established root systems.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Rice (Transplanted & Direct Sown) | Grasses (Barnyard Grass, Jungle Rice) |
| Rice (Transplanted & Direct Sown) | Sedges (Rice Flatsedge, Umbrella Sedge) |
| Rice (Transplanted & Direct Sown) | Broadleaf Weeds (Water Primrose, False Daisy) |
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) |
|---|---|---|---|---|
| Rice (Paddy) | 600 - 750 ml | 200 L | ~3.0 - 3.75 ml | 90 Days |
*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 between 0 to 5 Days After Transplanting (DAT) or sowing. Late application reduces effectiveness.
- Mixing: Shake the bottle well. Mix the recommended dose with clean water. The EW formulation mixes easily without agitation.
- Coverage: Spray uniformly over the standing water in the paddy field.
- Water Management: Do not flood the field for 24 hours after application. This allows the herbicide to bind to the soil surface. After 24 hours, maintain standing water to suppress further weed growth.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Is Hifit Plus safe for fish in my paddy field?
Yes, Hifit Plus has a favorable toxicity profile and is reported as non-toxic to fish, making it suitable for integrated rice-fish farming systems.
2. Can I use Hifit Plus on weeds that have already grown?
No. This is a pre-emergence herbicide. It works best on weeds that are just germinating. If weeds have already developed leaves and roots (beyond 5 days), its efficacy drops.
3. What makes the EW formulation better than EC?
EW (Emulsion in Water) is water-based, eliminating harsh organic solvents like xylene. This prevents "crop shock" or yellowing of rice leaves and is better for the environment.
4. When is the best time to apply?
The ideal window is 0 to 5 Days After Transplanting (DAT). Early application ensures the chemical barrier is formed before weeds can start competing for nutrients.
5. How much water should I use per acre?
It is recommended to use approximately 200 Litres of water per acre to ensure thorough coverage of the field.
