Heera-44 Herbicide: The Ultimate Broadleaf Weed Killer (2,4-D Ethyl Ester 38% EC)
Eliminate stubborn weeds like Bathua and Motha with the power of Heera-44.
Heera-44 by HPM Chemicals is a trusted, broad-spectrum herbicide designed to protect your Wheat, Maize, and Sugarcane crops. Formulated with 2,4-D Ethyl Ester 38% EC, it penetrates the tough, waxy leaves of weeds faster than standard solutions, ensuring your crop gets all the nutrition it deserves without competition.
Note: This is a chemical herbicide, not to be confused with "Heera" hybrid seeds or the "Pusa-44" rice variety.
Why Choose This Product? Key Benefits
-
⏱️
Fast Penetration: The special "Ethyl Ester" formula cuts through the waxy coating of weed leaves rapidly, ensuring the chemical is absorbed quickly.
-
🛡️
Broad Spectrum Control: Effectively kills a wide range of broadleaf weeds (like Bathua) and difficult sedges (like Motha/Nutgrass) that other herbicides miss.
-
⏳
Systemic Action: It doesn't just burn the leaves; it travels down to the roots and rhizomes, killing the weed from the inside out to prevent regrowth.
-
🌧️
Rainfast Nature: Due to rapid absorption, Heera-44 remains effective even if it rains 1-2 hours after spraying, unlike salt-based formulas that wash away.
-
🌿
Crop Safe: When used at the recommended time (e.g., tillering stage in wheat), it is highly selective, killing the weeds while leaving your crop harmless.

How It Works: Mode of Action
Heera-44 acts as a "Synthetic Auxin," mimicking the plant's natural growth hormones but with much higher intensity.
- Absorption: Upon spraying, the liquid is absorbed by the leaves and stems of the weed.
- Translocation: The chemical travels through the plant's system, reaching the growing tips and roots.
- System Collapse: It triggers uncontrolled, chaotic cell division. The weed stems twist and curl (epinasty), the nutrient transport system gets blocked, and the weed eventually starves and dies.
Crops like Wheat and Maize have natural enzymes to detoxify this chemical, keeping them safe while the weeds perish.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Wheat | Chenopodium album (Bathua), Melilotus (Senji), Fumaria, Asphodelus (Piazi) |
| Maize & Sorghum | Trianthema (Carpet weed), Striga (Witchweed), Tribulus, Cyperus (Motha) |
| Sugarcane | Cyperus rotundus (Motha), Convolvulus (Bindweed), Broadleaf weeds |
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) |
|---|---|---|---|---|
| Wheat | 300 - 500 ml | 180 - 200 L | 2 - 2.5 ml | Refer to Label |
| Maize | 600 - 1000 ml | 160 - 180 L | 4 - 6 ml | Refer to Label |
| Sugarcane | 1400 - 2000 ml | 200 L | 7 - 10 ml | Refer to Label |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Always check the official leaflet for crop-specific PHI.
How to Apply: Best Practices
- Timing (Wheat): Apply 30-40 Days After Sowing (DAS) when the crop is in the tillering stage. Avoid spraying too early (seedling stage) or too late (booting stage) to prevent injury.
- Mixing: This is an EC (oil-based) formulation. Mix well in water to form a stable milky-white emulsion before spraying.
- Coverage: Use a Knapsack sprayer with a Flat Fan nozzle to ensure even coverage over the weeds. Ensure sufficient soil moisture is present.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Caution: Do not spray if sensitive crops like Cotton, Okra, or Tomatoes are growing nearby, as the vapors can drift and damage them.
Frequently Asked Questions
1. Is Heera-44 the same as the Pusa-44 rice variety?
No. Heera-44 is a chemical herbicide used to kill weeds. Pusa-44 is a specific variety of rice seed. They are completely different products.
2. Can I use Heera-44 on Cotton or vegetables?
Absolutely NOT. Cotton, Okra, and Tomatoes are extremely sensitive to 2,4-D. Even a small amount of drift (vapor) from Heera-44 can destroy these crops.
3. Does Heera-44 control Motha (Nutgrass)?
Yes, unlike many other herbicides, Heera-44 is effective against sedges like Cyperus (Motha) when used at the correct dosage.
4. What happens if it rains after spraying?
Heera-44 is an ester formulation, meaning it is rainfast within 1-2 hours. If it rains after this period, re-spraying is usually not required.
5. Why is the soil moisture important?
Herbicides work best on actively growing weeds. Moisture helps the weed absorb the chemical and transport it to the roots for a complete kill.
