HPM Gadar & Gadar Max (Pendimethalin): Expert Pre-Emergence Weed Control
Stop weeds before they start with India's trusted choice for Cotton, Soybean, and Wheat.
Manual weeding is expensive and labor is hard to find. HPM Gadar and the advanced Gadar Max offer a powerful chemical solution to keep your fields clean from day one. Whether you choose the cost-effective Gadar (EC) or the heat-resistant Gadar Max (CS) with "Capsule Lock" technology, you are guaranteed robust protection against tough grasses and broadleaf weeds.
Best For: Farmers looking to replace manual labor with a safe, long-lasting pre-emergence herbicide.
Why Choose This Product? Key Benefits
- ⏱️Saves Labor Costs: One spray replaces 8-10 days of manual labor, saving you up to ₹2000 per acre.
- ?️Crop Safety Assured: Safe for sensitive crops like Cotton and Soybean when applied correctly, ensuring zero damage to your yield.
- ⏳Long-Lasting Control: Creates a chemical barrier that stops weeds for weeks, allowing your crop to establish a healthy canopy.
- ?️Weather Resistant (Gadar Max): The CS formulation uses "Capsule Lock" technology, preventing the medicine from evaporating even in high temperatures (May-June sowing).
- ?Broad Spectrum Action: Effectively kills both narrow-leaf grasses (like Jungle Rice) and broad-leaf weeds (like Amaranthus) simultaneously.

How It Works: Mode of Action
Pendimethalin acts as a smart barrier on the soil surface. It does not kill established plants; instead, it catches weeds the moment they try to sprout.
- Chemical Blanket: After spraying, the herbicide forms a thin, toxic layer in the top 1-2 inches of the soil.
- Absorption: As weed seeds germinate, their young roots and shoots touch this layer and absorb the chemical.
- Cell Arrest: The medicine stops cell division (mitosis) in the weed, causing the seedling to die before it can even emerge from the ground.
Note: Crop seeds are sown deeper than this chemical layer, which keeps them safe.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Jungle Rice (Echinochloa), Crabgrass, Amaranthus, Carpet Weed |
| Soybean | Echinochloa colonum, Euphorbia, Commelina spp. |
| Wheat | Phalaris minor (Canary Grass), Chenopodium (Bathua) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Using high water volume is critical for creating a uniform soil barrier.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 600-700 ml (Gadar Max CS) 1000-1500 ml (Gadar EC) | 200 L | 3 - 3.5 ml (CS) 5 - 7 ml (EC) | 110 |
| Soybean | 600-700 ml (Gadar Max CS) 1000-1500 ml (Gadar EC) | 200 L | 3 - 3.5 ml (CS) 5 - 7 ml (EC) | 90 |
| Wheat | 1000-1500 ml (Gadar EC) | 200 L | 5 - 7 ml | 100 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
[Image of flat fan nozzle spray pattern]- Timing: Apply within 0 to 3 days of sowing (Pre-emergence). There must be moisture in the soil.
- Mixing: Use 200 Liters of water per acre. Good coverage is essential for the chemical barrier to work.
- Coverage: Use a "Flat Fan" or "Flood Jet" nozzle. Do not use cone nozzles (insecticide nozzles) as they cause drift.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. The EC formulation is orange and stains easily—this helps you see where you sprayed.
Frequently Asked Questions
1. What is the difference between Gadar (EC) and Gadar Max (CS)?
Gadar Max uses CS (Capsule Suspension) technology. It is better for hot weather (Cotton/Soybean sowing) because it doesn't evaporate easily. It also requires a lower dose per acre than the EC version.
2. Can I use Gadar on a standing crop?
No. Gadar is a pre-emergence herbicide. It must be sprayed immediately after sowing but before the weeds and crop sprout (0-3 days).
3. Does it kill weeds that have already grown?
No. Pendimethalin only stops seed germination. If weeds have already emerged, you will need a post-emergence herbicide or manual weeding.
4. Can I mix it with other chemicals?
You can mix it with 2,4-D for burndown in fallow fields, but avoid mixing with strong alkalines (like Bordeaux mixture). Always perform a compatibility jar test first.
5. Is it safe for fish?
No. Pendimethalin is toxic to fish. Do not use it in areas where aquaculture is practiced alongside rice cultivation or near fish ponds.
