Hacker Herbicide (Pretilachlor 30.7% EC): The Ultimate Weed Solution for Rice
Secure your paddy yield from Day 1 with Nichino's advanced pre-emergence technology.
Hacker is a specialized herbicide designed for the modern rice farmer. Whether you are using traditional transplanting methods or Direct Seeded Rice (DSR), Hacker provides a powerful shield against stubborn weeds.
The Problem: Weeds like Barnyard grass compete with your rice for nutrients in the critical first 30 days. Manual weeding is expensive and labor is hard to find.
The Solution: Hacker (Pretilachlor 30.7% EC) stops weeds before they even start, ensuring your crop gets 100% of the nutrition.
Why Choose This Product? Key Benefits
- ⏱️Early Action: Applied within 0-5 days of planting, it kills weeds at the moment of germination.
- ?️Maximum Safety: Features a "Safener" (Fenclorim) that protects your rice seedlings while destroying weeds.
- ⏳Long-Lasting Control: One application keeps the field weed-free during the critical crop establishment phase.
- ?️Rain & Water Fast: Works effectively in wet soil and standing water conditions common in paddy fields.
- ?Broad Spectrum: Targets tough grasses (like Barnyard grass), sedges, and broadleaf weeds simultaneously.

How It Works: Mode of Action
Hacker works by creating a chemical barrier on the soil surface. It attacks weeds at the cellular level before they can grow.
- Absorption: The herbicide is absorbed rapidly through the shoot (coleoptile) of the germinating weed.
- Disruption: It stops the production of Very Long Chain Fatty Acids (VLCFAs), which are essential for cell growth and division.
- Selective Safety: While weeds die, the rice plant uses the added Safener to break down the chemical, keeping the crop healthy.
Note: This product is preventative. It must be applied before weeds emerge.

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) |
|---|---|---|---|---|
| Rice (Paddy) | 600 - 800 ml | 200 Litres | 3 - 4 ml | Safe till Harvest |
| Rice Nursery | As per area | Sufficient Qty | 3 - 4 ml | -- |
| Direct Seeded Rice | 600 ml | 200 Litres | 3 ml | Safe till Harvest |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Since this is a pre-emergence spray, it is generally safe by harvest time.
How to Apply: Best Practices
- Timing: Apply 0-3 days after sowing (DSR) or 0-5 days after transplanting. Weeds must not have emerged yet.
- Mixing: Can be sprayed using a Knapsack sprayer or mixed with sand (20-25kg dry sand/acre) for broadcasting.
- Coverage: If spraying, use a Flat Fan or Flood Jet nozzle. Do not use Cone nozzles.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not drain paddy water into fish ponds.
Frequently Asked Questions
1. Can I use Hacker if the weeds have already grown (2-3 leaves)?
No. Hacker is a pre-emergence herbicide. It only works if applied before weeds appear above the soil.
2. Is Hacker safe for fish in my paddy field?
No. Pretilachlor is toxic to aquatic organisms. Do not apply near fish ponds or drain treated water into aquaculture areas.
3. Why is Hacker safer for rice than other herbicides?
It contains a chemical "safener" that helps the rice plant digest the herbicide, while weeds (which lack this ability) are killed.
4. Can I mix Hacker with sand instead of spraying?
Yes. You can mix 600ml of Hacker with 20-25 kg of dry sand per acre and broadcast it uniformly over standing water.
5. Is there an antidote for accidental poisoning?
No specific antidote exists. Treatment is symptomatic. In case of ingestion or severe exposure, seek medical help immediately.
