Heera Super Herbicide (2,4-D Sodium Salt 80% WP)
The "Diamond" Standard for Broadleaf Weed Control in Wheat & Maize
Heera Super by HPM Chemicals is a powerful systemic herbicide designed to eliminate tough broadleaf weeds. Unlike manual weeding, which is expensive and labor-intensive, Heera Super offers a cost-effective solution (nearly 10x cheaper than labor) to keep your fields clean. It is formulated as an 80% Wettable Powder (WP), making it highly soluble and safer to use than volatile Ester formulations.
Best For: Controlling Bathua, Gajri, and other broadleaf weeds in Wheat, Maize, Sorghum, and Sugarcane.
Why Choose Heera Super? Key Benefits
-
⏱️
Systemic Action: Absorbed by roots and leaves, it travels to the growing tips to kill the weed from the inside out.
-
🛡️
Crop Safety: Being a Sodium Salt formulation, it has low volatility, reducing the risk of vapor drift damaging neighboring sensitive crops like cotton or mustard.
-
⏳
Cost Effective: At approximately ₹250 per acre, it is significantly more affordable than manual weeding (which can cost ₹1500+).
-
🌧️
High Solubility: The high-quality 80% WP formulation dissolves quickly in water without clogging nozzle filters.
-
🌿
Broad Spectrum: Effectively controls Bathua (Chenopodium), Gajri (Fumaria), and even Water Hyacinth in aquatic zones.

How It Works: Mode of Action
Heera Super works by mimicking the plant's natural growth hormone (Auxin). When sprayed, it is absorbed by the weeds and causes a "biological overload."
- Rapid Absorption: Enters through leaves and roots, moving to the growing tips.
- Uncontrolled Growth: It forces the weed's cells to divide rapidly and abnormally (twisting/epinasty).
- Vascular Collapse: The plant's transport system (phloem/xylem) gets crushed by cell growth, starving the weed to death.
Result: The weed curls, wilts, and dies, while the cereal crop (which can detoxify the chemical) remains healthy.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Wheat | Chenopodium album (Bathua), Fumaria (Gajri), Sweet Clover, Vicia sativa |
| Maize & Sorghum | Trianthema monogyna (Carpet weed), Amaranthus, various broadleaf weeds |
| Sugarcane | Cyperus iria (Sedge), Convolvulus (Bindweed), Climbing vines |
| Non-Crop / Aquatic | Eichhornia crassipes (Water Hyacinth), Parthenium, Lantana |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Do not overdose.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Wheat | 250 - 400g | 150 - 200 L | 1.5 - 2g | Refer to Label |
| Maize / Sorghum | 300 - 400g | 200 L | 1.5 - 2g | Refer to Label |
| Sugarcane | 300 - 800g | 200 - 250 L | 2 - 3g | Refer to Label |
| Aquatic Weeds | 500 - 800g | Specific to area | -- | -- |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Always check the official product leaflet for crop-specific PHI.
How to Apply: Best Practices
- Wheat Timing: Apply strictly between 30-40 days after sowing (DAS). Applying too early (1-2 leaf stage) can cause "club wheat" or deformity. Applying too late can reduce yield.
- Mixing Warning (Snotballs): Do NOT mix directly with Zinc Sulphate. It can react to form a sticky, jelly-like mass ("snotballs") that clogs nozzles. Always perform a "Jar Test" before mixing with other chemicals.
- Coverage: Use 150-200 Litres of water per acre. For Maize, use a "Directed Spray" to avoid the chemical entering the central crop whorl.
- Safety: Always wear PPE (gloves, mask, goggles) during the "creaming" (mixing) phase to avoid eye irritation from the powder.
Frequently Asked Questions
1. Can I use Heera Super on Cotton or Mustard?
No! Cotton, Mustard, and vegetables are broadleaf crops. Even a small drift of Heera Super will severely damage or kill them.
2. What happens if I spray Heera Super in Wheat too early?
Spraying before 30 days can cause crop deformity (malformed ears) because the young wheat plant cannot detoxify the chemical fast enough.
3. Can I mix Zinc or Urea with this herbicide?
Mixing with Urea is generally okay, but mixing with Zinc Sulphate is risky as it may curdle the mixture. Always use a standalone spray for best results.
4. What is the difference between Heera Super and Heera-44?
Heera Super is a Sodium Salt (WP) which is less volatile and safer for neighbors. Heera-44 is an Ester formulation which is more volatile and creates vapors that can drift further.
5. Does it control grassy weeds like Phalaris minor (Gulli Danda)?
No. Heera Super is specific to broadleaf weeds (dicots). It does not kill grasses.
