Pendistar Herbicide (Pendimethalin 30% EC) by Nichino
The "First Line of Defense" against stubborn weeds in Wheat, Cotton, Rice, and Soybean.
Manual weeding is expensive and labor is hard to find. Pendistar is your economical solution. Manufactured by Nichino India (a subsidiary of Japan’s Nihon Nohyaku), this pre-emergence herbicide creates a chemical barrier on the soil surface that stops weeds before they even grow.
Best for: Farmers looking for Japanese quality standards to control Phalaris minor (Mandusi), Barnyard grass, and broadleaf weeds efficiently.

⏱️
Saves Time & Labor: Stops weed competition early (0-3 days), removing the need for costly manual weeding later in the season.
-
🛡️
Safe for Crops: Advanced "positional selectivity" ensures your crop seeds (planted deep) are safe while surface weeds are destroyed.
-
⏳
Long-Lasting Control: Provides extended residual activity (30-45 days), keeping fields clean during the critical crop establishment phase.
-
🌧️
Weather Resistant: Binds tightly to soil particles, reducing leaching into groundwater. (Note: Requires soil moisture to activate).

How It Works: Mode of Action
Pendistar works by stopping cell division (mitosis) in young weeds.
- Stops Growth: It binds to tubulin proteins, preventing the formation of microtubules needed for cell splitting.
- Root Failure: The weed's root tip swells (known as "Club Root"), and it loses the ability to absorb water.
- Emergence Block: The weed seedling dies underground or immediately after trying to break the soil surface.
Note: It does not kill established weeds. It must be applied before weeds sprout.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Wheat | Phalaris minor (Canary Grass), Chenopodium (Bathua), Melilotus |

| Rice (Paddy) | Barnyard Grass, Small Sedges (Fimbristylis), Eclipta alba |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" and use sufficient water (200 Liters) to create a uniform soil barrier.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Wheat | 1250 ml | 200 L | 6.25 ml | Refer to Label |
| Rice / Cotton | 1000 - 1650 ml* | 200 L | 5 - 8 ml | Refer to Label |
| Soybean | 800 - 1250 ml | 200 L | 4 - 6 ml | Refer to Label |
*Note: For Cotton, use higher dose (1650 ml) for heavy clay/black soils and lower dose (1000 ml) for light sandy soils.
How to Apply: Best Practices
- Timing: Apply within 0 to 3 days after sowing/transplanting. The soil surface must be sprayed before weeds emerge.
- Mixing: Use a Flat Fan Nozzle only. Do NOT use hollow cone nozzles.
- Coverage: Ensure soil has adequate moisture. The spray must form a continuous film on the soil. Do not disturb the soil after spraying.
- Safety: Always wear PPE (gloves, mask, goggles). This product stains skin yellow—wear protection!
Frequently Asked Questions
1. Can I use Pendistar on standing weeds?
No. Pendistar is a pre-emergence herbicide. It only kills seeds that are about to sprout. It will not kill weeds that have already emerged.
2. Why is using 200 Liters of water important?
Farmers often use less water to save time, but this causes "gaps" in the chemical barrier on the soil. Weeds will grow through these gaps. Use the full water volume for best results.
3. Does this product stain?
Yes. Pendimethalin EC is known to stain clothes and skin a bright orange/yellow color. This is not highly toxic but is hard to wash off. Always wear gloves.
4. What is the difference between Pendistar and Pendixtra?
Pendistar is a 30% EC (Liquid) formulation, which is economical and fast-acting. Pendixtra is a capsule suspension (CS) that releases slowly and stains less, but is more expensive.
5. Can I use it on dry soil?
For best results, the soil should be moist. Moisture activates the chemical. If the soil is completely dry, irrigate lightly after application or ensure rain is expected.
