HPM Heera-77 Herbicide (2,4-D Amine Salt 58% SL)

The "Diamond Standard" for Safe & Effective Broadleaf Weed Control.

HPM Heera-77 is a powerful, selective systemic herbicide designed to eliminate tough broadleaf weeds (dicots) in crops like Wheat, Maize, Sorghum, and Sugarcane. Formulated as a soluble liquid (Amine Salt), it offers a crucial advantage over older ester formulations: Low Volatility. This means it stays where you spray it, significantly reducing the risk of vapor drift damaging nearby sensitive crops like cotton or vegetables.

Best For: Farmers looking for a cost-effective solution to control weeds like Bathua, Chaulai, and Bindweed without clogging nozzles or risking crop safety.

Why farmers choose itWhy Choose This Product? Key Benefits
  • ⏱️ Systemic Root Kill: Absorbed through leaves and moves to the roots, ensuring the weed is killed completely and does not grow back.
  • ?️ Maximum Safety (Low Volatility): Unlike 2,4-D Ester, this Amine formulation does not turn into vapor in heat, making it safer for mixed-cropping areas.
  • ⏳ Broad Spectrum Control: Effectively controls a wide variety of annual and perennial broadleaf weeds, including sedges (motha) and aquatic weeds.
  • ?️ High Solubility: Dissolves instantly in water to form a clear solution. No sediment, no nozzle clogging, and easy tank mixing.
  • ? Crop Safe Selectivity: Advanced enzymes in crops like Wheat and Maize detoxify the chemical rapidly, keeping your crop safe while weeds perish.

Product scienceHow It Works: Mode of Action

Heera-77 works by mimicking the plant's natural growth hormone (Auxin). When weeds absorb it, it triggers a "growth overdose."

  1. Absorption & Translocation: The liquid penetrates the leaves and travels through the phloem to the growing tips and roots.
  2. Uncontrolled Growth: It forces the weed cells to divide rapidly and chaotically, blocking the transport of food and water.
  3. System Collapse: The weed stems curl and twist (epinasty), the roots starve, and the plant dies within 2-3 weeks.

Note: Visual symptoms like curling appear within days, but total death takes time as the root system is destroyed.

How to applyDosage & Application Guide

The Golden Rule: Always follow the "Dose per Acre" for accurate results. Using Flat Fan nozzles is mandatory for even coverage.

How to applyDosage per Acre, Litre, & Pre-Harvest Interval (PHI)
CropDose (ml / Acre)Water (L / Acre)Dose (ml / Litre)PHI (Days)
Wheat340 – 520 ml200 – 400 L~1.5 – 2.5 ml60+
Maize / Sorghum344 – 1200 ml*200 – 300 L~1.5 – 4 ml60+
Sugarcane2520 ml300 – 400 L~6 – 8 ml60+
Non-Crop Area1800 ml400 L~4.5 mlN/A

*Note: Maize typically requires lower doses (approx 344ml) compared to Sorghum. Always conduct a directed spray in Maize/Sorghum to avoid spraying directly into the crop whorl.

Useful detailsHow to Apply: Best Practices
  • Timing (Wheat): Apply strictly between 30 to 35 Days After Sowing (DAS). Applying too early can deform leaves; applying too late (after jointing) can reduce grain yield.
  • Mixing: This is an SL formulation. Fill the tank half with water, add the required dose of Heera-77, and then top up with water. Agitate slightly.
  • Coverage: Use Flat Fan Nozzles or Flood Jet nozzles. Do NOT use hollow cone nozzles (fine mist) as they cause drift. Ensure the soil has good moisture at the time of spraying.
  • Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not mix with highly acidic chemicals.
Use with careSafety & Disclaimer

Always read and follow the instructions on the official product label. The information provided here is for guidance only. Use personal protective equipment (PPE) during application. Avoid spraying on windy days to prevent drift.
