Pendamil Herbicide (Pendimethalin 30% EC) by IIL
The "Chemical Insurance" for your crop: Stop weeds before they start.
Pendamil is a premium pre-emergence herbicide brought to you by Insecticides (India) Ltd (IIL). Designed for modern Indian agriculture, it provides a powerful chemical barrier on the soil surface that prevents weed seeds from germinating. By controlling weeds in the critical first 30-40 days, Pendamil saves you labor costs and protects your yield in crops like Cotton, Paddy, Wheat, and Soybean.
Best For: Farmers seeking a cost-effective, labor-saving solution to keep fields weed-free during the sowing and transplanting stages.
Why Choose This Product? Key Benefits
- ⏱️Early Action: Kills weeds within 0-3 days of sowing, ensuring your crop starts clean without competition.
- ?️Long-Lasting Barrier: Provides residual control for 30-40 days, significantly reducing the "weed seed bank" in your soil.
- ⏳Labor Saver: Eliminates the need for expensive manual weeding during the busy sowing season.
- ?️Broad Spectrum: Effectively controls resistant weeds like Phalaris minor (Mandusi) and various broadleaf species.
- ?Versatile & Safe: Safe for use in major crops including Cotton, Paddy, Wheat, Soybean, and Pulses when used as directed.

How It Works: Mode of Action
Pendamil acts as a "mitotic poison" that targets the cell division process in weeds.
- Barrier Formation: Upon spraying, Pendamil forms a thin chemical film on the top 1-2 inches of the soil surface.
- Absorption: As weed seedlings germinate, their emerging roots or shoots touch this treated layer and absorb the chemical.
- Growth Arrest: The active ingredient binds to tubulin in the plant cells, stopping cell division. The weed seedling dies before it can even emerge from the ground.
Note: Crop seeds are safe because they are sown deeper than the chemical layer.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Annual Grasses, Amaranthus viridis, Euphorbia spp. |
| Paddy (Rice) | Echinochloa spp. (Barnyard grass), Sedges, Jungle Rice |
| Wheat | Phalaris minor (Gulli Danda), Bathua (Chenopodium) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Ensure high water volume (200L/Acre) for complete soil coverage.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 1000 - 1600 ml | 200 - 250 L | 5 - 8 ml | Safe (Pre-emergence) |
| Wheat | 1000 - 1200 ml | 200 L | 5 - 6 ml | Safe (Pre-emergence) |
| Paddy (Rice) | 1300 - 2000 ml | 200 - 280 L | 6 - 8 ml | Safe (Pre-emergence) |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. For Pendamil, safety is ensured by application timing (0-3 days after sowing).
How to Apply: Best Practices
- Timing: Apply within 0 to 3 days after sowing (DAS). The soil must be moist for the chemical to bind effectively.
- Mixing: Conduct a physical compatibility check ("Jar Test") before tank-mixing with other herbicides.
- Coverage (Reverse Foot Method): Always walk backward while spraying ("Reverse Foot" technique). This prevents you from stepping on the treated soil and breaking the chemical barrier.
- Safety: Always wear PPE (gloves, mask, goggles). Pendamil leaves a yellow/orange stain, so avoid contact with skin and clothing. Wash hands thoroughly after use.
Frequently Asked Questions
1. Does Pendamil kill weeds that have already grown?
No. Pendamil is a pre-emergence herbicide. It only kills weeds as they germinate. It will not kill weeds that are already visible above the soil.
2. Why must I walk backward while spraying?
Walking backward ensures you do not step on the chemical layer you just sprayed. Footprints break the film, creating gaps where weeds can grow.
3. Can I use it on dry soil?
No. Pendamil needs soil moisture to activate. If the soil is dry, irrigate lightly before or immediately after application.
4. Does it stain?
Yes. Pendimethalin is a dye-based chemical and leaves a yellow/orange stain on skin and clothes. Wear protective gear to avoid this.
5. Is it safe for my Cotton crop?
Yes, it is highly safe for Cotton when applied within 3 days of sowing. It is particularly effective in heavy soils (Black Cotton Soil).
