HPM Gadar & Gadar Max (Pendimethalin) Herbicide
The Ultimate Pre-Emergence Weed Solution for Cotton, Soybean, Wheat & Chilli.
Stop weeds before they even start. HPM Gadar (30% EC) and the advanced Gadar Max (38.7% CS) are powerful pre-emergence herbicides designed to protect your crops from Day 1. By creating a chemical barrier on the soil surface, Gadar prevents weed seeds from sprouting, saving you labor costs and ensuring your crop gets all the nutrients it needs without competition.
Best for: Farmers looking for a labor-saving substitute to manual weeding in Kharif and Rabi crops.

How It Works: Mode of Action
Pendimethalin acts as a selective "growth stopper" for weeds.
- Barrier Formation: Upon spraying, it creates a thin chemical layer on the top 1-inch of the soil.
- Absorption: As weed seeds germinate, their emerging roots and shoots touch this layer and absorb the chemical.
- Termination: The herbicide stops cell division in the weed's roots. The weed seedling dies before it can emerge from the ground.
Note: It does not kill established weeds; it only kills sprouting seeds.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton & Soybean | Barnyard grass (Sama), Jungle Rice, Carpet Weed (Trianthema), Purslane. |
| Wheat | Phalaris minor (Gulli Danda), Chenopodium (Bathua), Melilotus. |
| Chilli & Pulses | Annual grasses and broadleaf weeds like Amaranthus. |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Use Gadar Max (CS) for better results in hot weather.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (Gadar Max CS) | Dose (Gadar 30% EC) | Water (L / Acre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 600 - 700 ml | 1000 - 1500 ml | 200 L | 110 |
| Soybean | 600 - 700 ml | 1000 - 1500 ml | 200 L | 90 |
| Wheat | 600 - 700 ml | 1000 - 1500 ml | 200 L | 100 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply within 0 to 3 days of sowing (Pre-emergence). The soil must have moisture, but the crop/weeds should not have emerged yet.
- Mixing: Use a Flat Fan or Flood Jet nozzle. Do not use Cone nozzles. Ensure thorough coverage of the soil surface.
- Coverage: Walk backward while spraying to avoid breaking the chemical layer with your footsteps.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. What is the difference between Gadar (EC) and Gadar Max (CS)?
Gadar Max uses "Capsule Suspension" technology. It is better for hot summer days as it doesn't evaporate easily and provides longer protection compared to the standard EC liquid.
2. Can I use Gadar on a standing crop (Post-emergence)?
No! Gadar is strictly a PRE-emergence herbicide. Spraying it on standing crops can stunt their growth or damage them. Use it only within 3 days of sowing.
3. Will Gadar kill weeds that have already sprouted?
No, Gadar only kills weed seeds as they germinate. It will not kill large weeds that are already visible above the soil.
4. Can I mix Gadar with other chemicals?
Gadar can generally be mixed with 2,4-D for clearing fallow land, but avoid mixing it with highly alkaline substances like Bordeaux mixture.
5. What happens if it rains after spraying?
A light rain helps incorporate Gadar into the soil, which is good. However, very heavy rain immediately after spraying might wash the chemical away, reducing effectiveness.
