Pendamil Super Herbicide (Pendimethalin 38.7% CS)
Advanced Pre-Emergence Weed Control for Soybean, Cotton, Chilli & Onion
Stop weeds before they start. Pendamil Super by Insecticides (India) Limited is a next-generation herbicide designed to keep your fields clean from day one. Unlike older yellow sprays (EC formulations), this advanced Capsule Suspension (CS) technology locks the active ingredient inside microscopic shells.
The Result? Longer protection (up to 45 days), better safety for your crops, and no messy staining on your hands or equipment. It creates a strong chemical barrier on the soil that stops grasses and broadleaf weeds the moment they try to germinate.
Why Choose This Product? Key Benefits
-
⏱️
45 Days of Protection: Slow-release capsules ensure the medicine stays active longer, protecting your crop during the critical early weeks.
-
🛡️
Maximum Crop Safety: The water-based CS formula has no harsh solvents, preventing "solvent burn" on young seedlings.
-
⏳
Weather Resistant: The protective shell prevents the spray from evaporating in the hot sun (volatility) or breaking down under UV light.
-
🌧️
No Staining & Low Odor: Unlike old 30% EC versions, this doesn't stain your skin yellow instantly and has no strong chemical smell.
-
🌿
Broad Spectrum Control: Effectively kills tough weeds like Barnyard grass, Jungle rice, and Purslane.

How It Works: Mode of Action
Pendamil Super works by disrupting cell division in growing weeds.
- Barrier Formation: After spraying, it forms a thin, continuous chemical film on the top layer of the soil.
- Absorption: As weed seeds germinate and try to push through this layer, their roots and shoots absorb the herbicide.
- Root Inhibition: The chemical stops the weed's cells from dividing (Mitosis). The roots become swollen and "clubbed," failing to grow. The weed seedling dies before it ever emerges from the ground.
Note: It does not kill established weeds. It must be applied before weeds appear.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Soybean & Cotton | Barnyard grass, Jungle rice (Echinochloa), Purslane, Lambsquarters |
| Chilli & Onion | Amaranthus (Pigweed), Carpet weed, Canary grass, Crowfoot grass |
| Groundnut & Cumin | Crabgrass, Foxtail grass, Goosegrass, and various broadleaf weeds |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" and ensure high water volume for a complete soil barrier.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Soybean | 600 - 700 ml | 150 - 200 L | 3.5 - 4 ml | 40 Days |
| Cotton | 600 - 700 ml | 150 - 200 L | 3.5 - 4 ml | 101 Days |
| Onion & Chilli | 600 - 700 ml | 150 - 200 L | 3.5 - 4 ml | 98 - 104 Days |
*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/transplanting. The soil must be moist. If weeds have already emerged, this product will NOT work.
- Mixing: Use a Flat Fan or Flood Jet nozzle. Do not use low water volume; you need at least 150 Liters per acre to create a gap-free barrier on the soil.
- Coverage: Ensure the field is well-prepared and free of large clods. Large soil lumps create "shadows" where weeds can hide and grow.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. What is the difference between 30% EC and this 38.7% CS?
The CS formulation uses micro-capsules. It lasts longer (45 days vs 20 days), doesn't evaporate in high heat, and doesn't stain your equipment yellow like the old EC liquid.
2. Can I use this on dry soil?
No. Pendamil Super needs soil moisture to activate. Apply immediately after sowing while the soil is moist, or irrigate lightly immediately after spraying.
3. Will it kill weeds that are already green and growing?
No. This is a pre-emergence herbicide. It only kills seeds as they try to germinate. For existing weeds, you need a post-emergence killer or manual weeding.
4. Can I mix it with other herbicides?
Yes, it is often tank-mixed with Imazethapyr for broader control in soybeans and pulses, but always perform a small compatibility test first.
5. Is it safe for the operator?
Yes, it is safer than EC formulations because it is water-based and has no harmful solvent fumes, but standard safety gear (mask/gloves) is still required.
