Heera Super Herbicide (2,4-D Sodium Salt 80% WP)
The trusted "Diamond" standard for cost-effective broadleaf weed control in Wheat, Maize, and Sugarcane.
Heera Super, manufactured by HPM Chemicals, is a powerful systemic herbicide based on 2,4-D Sodium Salt 80% WP. It offers a perfect balance of high potency and affordability for Indian farmers. Unlike volatile ester formulations, this Wettable Powder (WP) is engineered to dissolve quickly in water and carries a lower risk of vapor drift, making it safer for neighboring farms when used correctly.
Best For: Controlling stubborn broadleaf weeds like Bathua (Chenopodium) and Gajri in cereal crops.
Why Choose This Product? Key Benefits
- ⏱️Rapid Action: Absorbs quickly through roots and leaves to disrupt weed growth immediately.
- ?️High Crop Safety: Selective action targets broadleaf weeds while leaving narrow-leaf crops like wheat and maize unharmed (when used as directed).
- ⏳Low Volatility: Contains Sodium Salt, which creates significantly less vapor drift compared to Ester formulations.
- ?️Superior Solubility: The high-quality 80% WP formulation dissolves easily in water without clogging nozzle filters.
- ?Cost-Effective: Provides excellent weed control at approximately ₹200–₹250 per acre, making it 10x cheaper than manual weeding.

How It Works: Mode of Action
Heera Super mimics the plant's natural growth hormone (Auxin). When sprayed, it enters the weed's system and disrupts normal biological functions.
- Absorption: The active ingredient is absorbed through the leaves and roots, moving rapidly to the growing points (meristems).
- Over-Stimulation: It triggers uncontrolled cell division and elongation, causing the stem to twist and curl (epinasty).
- Vascular Collapse: The excessive growth crushes the plant's food and water transport channels (xylem and phloem), causing the weed to starve and die.
Note: Wheat and Maize plants can metabolize (break down) this chemical quickly, which is why they remain safe while the weeds die.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Wheat | Bathua (Chenopodium album), Gajri (Fumaria), Sweet Clover |
| Maize & Sorghum | Carpet Weed (Trianthema), Pigweed (Amaranthus), Nut Sedge |
| Sugarcane & Aquatic | Field Bindweed (Convolvulus), Water Hyacinth |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Ensure high water volume to prevent crop burn.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Wheat | 250 - 400 g | 150 - 200 L | ~ 2.0 g/L | See Label |
| Maize / Sorghum | 300 - 400 g | 200 L (High) | ~ 1.5 - 2.0 g/L | See Label |
| Sugarcane | 300 - 800 g | 200 - 250 L | ~ 3.0 g/L | See Label |
*Note: Dosage in grams (g) because Heera Super is a powder. PHI = Pre-Harvest Interval.
How to Apply: Best Practices
- Timing (Wheat): Strictly spray between 30 and 40 Days After Sowing (DAS). Too early damages yield; too late causes lodging.
- Mixing: Do NOT mix directly with Zinc Sulphate fertilizers. This causes "snotballs" (clumping). Perform a jar test first.
- Coverage: In Maize, use a directed spray to the inter-row spaces. Avoid spraying the central whorl of the plant.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. What is the best time to spray in Wheat?
The critical window is 30 to 40 days after sowing. Spraying earlier (1-2 leaf stage) can cause ear deformity.
2. Can I mix Heera Super with Zinc or Urea?
It is risky. 2,4-D Sodium Salt often reacts with Zinc to form sticky clumps that clog sprayers. Use as a standalone spray.
3. Is it safe for Cotton or Mustard nearby?
No. Cotton and Mustard are highly sensitive to 2,4-D drift. Even slight vapors can cause severe damage. Spray only on calm days.
4. Does it control grassy weeds like Phalaris (Gulli Danda)?
No. Heera Super is specific to broadleaf (dicot) weeds. It will not kill grasses.
5. What type of sprayer should I use?
A knapsack sprayer with a flat fan nozzle is recommended for uniform coverage and reduced drift.
