HPM Gadar Max Herbicide (Pendimethalin 38.7% CS)
The "Climate-Smart" solution for complete weed control in Soybean, Cotton, and Chilli.
HPM Gadar Max is an advanced pre-emergence herbicide designed to protect your crops from day one. Unlike older chemical sprays, Gadar Max uses Capsule Suspension (CS) Technology. This means the active chemical is locked inside microscopic shells, preventing it from evaporating in the hot sun. It creates a protective layer on the soil that stops weeds like Sawa and Viper Grass before they can even grow, saving you money on manual labor.
Best For: Farmers looking for long-lasting weed control (up to 40 days) without the staining and strong smell of traditional EC herbicides.
Why Choose This Product? Key Benefits
-
⏱️
40 Days of Protection: Slow-release capsules keep the medicine active in the soil longer, controlling late-growing weeds.
-
🛡️
No Stains & No Smell: The yellow dye is locked inside capsules. It won't stain your hands or clothes yellow like old EC sprays.
-
⏳
Saves 80% on Labor Costs: One spray replaces expensive manual weeding crews, saving you approx. ₹2400 per acre.
-
🌧️
Works in Hot Weather: Ordinary sprays evaporate at 40°C. Gadar Max stays stable on the soil until it rains or is irrigated.
-
🌿
Safe for Crops: Water-based formula prevents leaf burn and root damage to sensitive crops like Chilli and Onion.

How It Works: Mode of Action
Gadar Max works by stopping weed seeds from developing roots. It acts as a barrier on the top layer of the soil.
- Micro-Release: The polymer capsules release the herbicide slowly when they come in contact with soil moisture.
- Root Inhibition: When weed seeds (like Jungle Rice) try to germinate, they absorb the chemical. It stops their cell division (mitosis).
- Weed Death: Without proper roots, the weed seedlings cannot take up nutrients and die before they can emerge from the soil.
Note: Because crop seeds are planted deeper than the herbicide layer, they grow through it safely.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Soybean | Jungle Rice (Sawa), Viper Grass, Purslane (Portulaca) |
| Cotton | Large Crabgrass, Viper Grass, Pigweed (Chaulai) |
| Chilli & Onion | Barnyard Grass, Lambsquarters (Bathua) |
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) | Timing (Days) |
|---|---|---|---|---|
| Soybean | 600 - 700 ml | 200 L | ~3.5 ml | 0-3 Days (At Sowing) |
| Cotton | 600 - 700 ml | 200 L | ~3.5 ml | 0-3 Days (At Sowing) |
| Chilli / Onion | 600 - 700 ml | 200 L | ~3.5 ml | Pre-Transplant |
*Use 200 Liters of water per acre to ensure the herbicide covers every inch of the soil surface.
How to Apply: Best Practices
- Timing: Apply within 0 to 3 days of sowing. The soil must be moist for the capsules to activate.
- Mixing: Use high water volume (200 Liters/Acre). Low water volume results in "spotty" coverage and poor weed control.
- Coverage: Use a Flat Fan or Flood Jet (Cut) Nozzle. Do NOT use cone nozzles (used for insecticides), as they create mist that drifts away.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. How is Gadar Max better than normal Pendimethalin 30% EC?
Gadar Max uses CS (Capsule) technology. It does not fly off (evaporate) in the heat, gives 40 days of control vs 20 days for EC, and does not stain your hands yellow.
2. Will this herbicide kill my Cotton or Soybean crop?
No. Gadar Max stays on the top 1-2 inches of soil. Your crop seeds are planted deeper, so their roots grow safely below the herbicide layer.
3. What happens if it doesn't rain immediately after spraying?
The capsule protects the medicine. Unlike EC sprays that evaporate in 2-3 days without rain, Gadar Max waits on the soil surface until moisture arrives to activate it.
4. Can I mix other herbicides with Gadar Max?
Yes. For Soybean, you can follow Gadar Max (Pre-emergence) with Imazethapyr (Post-emergence) for the highest yield results.
5. Is it safe for fish?
No. Pendimethalin is toxic to aquatic life. Do not use it in fields where aquaculture (fish farming) is practiced nearby.
