Benpret - Bensulfuron Methyl 0.6% + Pretilachlor 6% GR - HPM
Benpret Herbicide by HPM
A ready-mix granular herbicide for early weed control in transplanted paddy, with HPM timing of 3–5 days after transplanting.
Composition: Bensulfuron-methyl 0.6% + Pretilachlor 6% GR.
Crop fit: Transplanted rice (paddy). Keep each target with its listed crop.
Before treatment: Check the current crop-specific rate, method, water and harvest directions.
Why Choose This Product? Key Benefits
- 🌾Transplanted-paddy fit: HPM provides a specific rice timing and hectare-based quantity.
- 🌱Early weed management: The stated timing is 3–5 days after transplanting seedlings.
- 🧩Two active ingredients: The ready mix combines distinct weed-growth mechanisms.
- 🎯Named weed coverage: The manufacturer lists three grasses and three broad-leaved weeds, with a separate general sedge claim.
- ⚖️Granular formulation: GR identifies a field granule, not a foliar spray concentrate.

How It Works: Mode of Action
The two active ingredients interrupt different growth processes in susceptible weeds: bensulfuron-methyl inhibits ALS, while pretilachlor inhibits very-long-chain fatty-acid synthesis.
- Place granules as directed: Follow the label for distribution and field-water conditions in transplanted paddy.
- Two growth pathways are interrupted: The mixture affects amino-acid production and fatty-acid synthesis in susceptible weeds.
- Early weed growth is suppressed: The manufacturer’s early timing targets the start of weed establishment, not a rescue treatment for large weeds.
A different brand name does not necessarily mean a different mode of action. Follow the crop label and a suitable resistance-management programme; do not rely repeatedly on the same group alone.
Target Crops & Weeds
HPM identifies these crop-and-target pairings. Check that the current supplied label includes your intended use.
| Crop | Target Weed(s) |
|---|---|
| Transplanted rice (paddy) |

Do not extend a target listed for one crop to another crop, or add uses from a differently formulated product.
Dosage & Application Guide
HPM’s published quantities are shown below. Confirm the complete crop programme on the current pack before applying.
Granule Quantity, Timing & Harvest Precautions
| Crop | Original product dose | Approx. dose / Acre | Spray water | PHI (Days) |
|---|---|---|---|---|
| Transplanted paddy | 10 kg / hectare | About 4.05 kg | Not a spray recipe | Confirm |
HPM states 10 kg product per hectare, equivalent to about 4.05 kg per acre. Apply within the label’s early window; HPM’s narrative states 3–5 days after transplanting.
The 3–5-day figure is application timing after transplanting, not the pre-harvest interval. A spray-water or per-litre dose is not provided for these granules.
Confirm field-water depth, water retention or drainage, distribution method, repeat or maximum applications, re-entry and harvest precautions on the supplied label before spreading.
How to Apply: Best Practices
- Match the target: Identify the crop and problem and check that the supplied label covers the intended treatment.
- Keep the granular method: Follow the current label for even granule distribution and paddy-water management. Do not make a spray solution from the acre quantity.
- Check mixtures separately: No universal tank-mix recommendation is made. Use another product or adjuvant only when the relevant labels permit it.
- Protect people and water: Follow protective-equipment and field-entry precautions, avoid drift and runoff, and observe the crop’s harvest interval.
Frequently Asked Questions
What does Benpret contain?Bensulfuron-methyl 0.6% plus pretilachlor 6% in a ready-mix granular formulation.
What is HPM’s stated rice timing?Within 3–5 days after transplanting seedlings, subject to the current pack directions.
What is the hectare-to-acre quantity?10 kg per hectare is approximately 4.05 kg per acre. Use the exact current label rate when measuring.
Does 3–5 days mean I can harvest then?No. It is application timing after transplanting, not a harvest interval. Confirm the separate harvest precautions.
How much goes into a spray tank?A spray-tank dose is not appropriate here. Follow the Benpret granule application and field-water directions.
