HPM Chlorimuron Ethyl 25% WP: Specialized Soybean Herbicide
Master the monsoon and protect your yield with HPM's targeted weed control solution.
HPM Chlorimuron Ethyl 25% WP is a selective, systemic post-emergence herbicide designed specifically for Soybean crops. Engineered to combat broadleaf weeds and sedges, this formulation ensures your crop gets the nutrients it needs without competition. In an era of unpredictable weather and "rogue rains," you need a formulation that sticks, absorbs quickly, and delivers consistent results.
Best for: Farmers seeking cost-effective, high-efficiency control of broadleaf weeds in Soybean fields.
Why Choose This Product? Key Benefits
-
⏱️
Rapid Absorption Action: Absorbed by roots and foliage within hours, stopping weed growth immediately to prevent nutrient theft from your crop.
-
🛡️
Systemic Crop Safety: Highly selective to Soybeans. It targets the enzymatic pathways of weeds while leaving your main crop healthy and stress-free.
-
⏳
Extended Residual Control: Provides long-duration protection, reducing the need for multiple sprays during the critical early growth stages.
-
🌧️
Weather Resilience: Formulated to withstand erratic weather. Once absorbed (2-6 hours), it remains effective even against light rains, crucial for unpredictable monsoon seasons.
-
🌿
Low Dosage Efficiency: High potency means you use less chemical per acre (15g), reducing logistic costs and environmental load compared to bulkier alternatives.

How It Works: Mode of Action
This herbicide operates via a systemic mechanism that targets the weed's internal growth systems:
- Absorption: It is rapidly taken up by both the roots and foliage of the target weeds.
- Translocation: The active ingredient moves through the Xylem and Phloem, reaching the growing tips (meristems) of the weed.
- Inhibition: It blocks the Acetolactate Synthase (ALS) enzyme. This stops the production of essential amino acids (Valine, Leucine, Isoleucine), causing the weed to stop growing within hours and die within 7-14 days.
Note: Soybeans have a natural metabolism to break down this chemical, keeping the crop safe.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Soybean | Broadleaf weeds (e.g., Cocklebur, Pigweed) |
| Soybean | Sedges (Cyperus spp.) |
| Paddy (Transplanted) | Select Broadleaf weeds & Sedges |
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 (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Soybean | 15 g | 200 L | 0.075 g | 65 |
| Paddy | 15 - 24 g | 200 L | 0.12 g | 60 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply as a post-emergence spray when weeds are in the 2-4 leaf stage (usually 15-25 days after sowing).
- Mixing: Dissolve the 15g sachet thoroughly in a small bucket first, then add to the main tank (Knapsack sprayer preferred). Use the Flat Fan nozzle for uniform coverage.
- Coverage: Ensure the soil has sufficient moisture at the time of application to help the chemical move to the roots.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not spray on windy days to avoid drift to non-target crops.
Frequently Asked Questions
1. Does rain affect this product?
Ideally, you need 2-6 hours of rain-free weather after spraying for absorption. However, once absorbed, it is rainfast. Avoid spraying if "violent" rains are forecast immediately.
2. Can I mix this with other insecticides?
It is generally not recommended to mix Chlorimuron Ethyl with organophosphate insecticides as it may increase crop stress. Always perform a jar test or consult an agronomist.
3. When will I see results?
Weeds stop growing within 24 hours. Visible yellowing/browning appears in 5-7 days, with complete death in 14 days.
4. Is it safe for the next crop?
Yes, if used at the recommended dosage (15g/acre). However, avoid planting sensitive crops like mustard or sunflower immediately after harvest in the same season without soil testing.
5. What is the shelf life?
2 years from the date of manufacturing, provided it is stored in a cool, dry place away from direct sunlight and moisture.
