Selector Herbicide (Imazethapyr 10% SL) – Expert Weed Control for Legumes
The ultimate early post-emergence solution for Soybean, Groundnut, and Pulses to maximize yields.
Selector is a systemic, broad-spectrum herbicide designed to eliminate tough weeds that compete with your crop for nutrition and sunlight. By controlling grasses, broadleaf weeds, and sedges in a single spray, it ensures your crop grows healthy and yield remains high.
Best For: Farmers seeking labor-free, cost-effective weed management in Soybean and Groundnut.
Why Choose This Product? Key Benefits
- ⏱️Saves Labor & Cost: Reduces reliance on manual weeding, cutting operational costs by nearly 80%.
- ?️Double Action Power: Absorbed through both roots and leaves, ensuring weeds are attacked from all angles.
- ⏳Long-Lasting Control: Provides residual control that prevents new weed germination for weeks after application.
- ?️Rainfast in 6 Hours: Effective even if it rains 6 hours after spraying; subsequent rain actually helps root absorption.
- ?Broad Spectrum: Controls three major weed types—Grasses, Broadleaf weeds, and Sedges (Motha)—in one shot.

How It Works: Mode of Action
Selector works by stopping the internal food factory of the weed. It is an ALS inhibitor that halts the production of essential amino acids required for plant growth.
- Absorption: The herbicide enters the weed rapidly through leaves and roots.
- Translocation: It travels through the plant’s system to the growing tips (meristems).
- Termination: It inhibits the ALS enzyme, causing the weed to stop growing, turn yellow, and die within 10-14 days.
Note: Leguminous crops naturally metabolize (break down) this chemical quickly, keeping them safe.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Soybean | Echinochloa (Sama), Commelina (Kena), Cyperus (Motha - suppression) |

| Black/Green Gram | Mixed flora of grasses and broadleaf weeds |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Soybean | 400 - 600 ml | 200 L | 2 - 3 ml | 75 |
| Groundnut | 400 - 600 ml | 200 - 280 L | 2 - 3 ml | 90 |
| Urad / Moong | 250 - 400 ml | 150 - 200 L | 1.5 - 2 ml | ~50 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply when weeds are in the 2-4 leaf stage (typically 15-25 days after sowing).
- Mixing: Use a Flat Fan or Flood Jet nozzle. Ensure continuous agitation in the tank.
- Coverage: Ensure soil has adequate moisture. Do not spray on dry, cracked soil or moisture-stressed weeds.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I mix Selector with other insecticides?
It is generally not recommended to mix Selector with other pesticides unless specifically advised, as it may reduce weed control or clog the nozzle.
2. Will the crop turn yellow after spraying?
You may see a temporary "Yellow Flash" on the crop leaves. This is normal; the crop will recover fully within 10-14 days without yield loss.
3. Can I plant Mustard immediately after harvesting Soybean?
No. Selector residues can persist in the soil. Avoid sensitive crops like Mustard or Vegetables in the immediate next season; Wheat or Gram (Chickpea) are safer options.
4. Does it control Motha (Cyperus rotundus)?
It suppresses Motha. It halts the growth for 30-40 days, allowing your crop to grow over it, but it may not kill the underground tubers completely.
5. What if it rains after spraying?
Selector is rainfast after 6 hours. If it rains after that, the efficacy is maintained. Light rain later can even help move the herbicide to the roots.
