Hachiman Herbicide (Quizalofop-ethyl + Imazethapyr)
The Ultimate "Tractor Brand" Solution for Weed-Free Soybean & Groundnut Fields.
Hachiman is a premium, broad-spectrum herbicide developed with Japanese technology (Nissan Chemical Corporation). It is specially designed to solve the toughest weed problems in Kharif crops. By combining two powerful active ingredients, it eliminates grasses, broadleaf weeds, and stubborn sedges (like Motha) in a single spray, ensuring your crop gets all the nutrients it deserves.
Best For: Farmers seeking complete, long-lasting weed control in Pulse and Oilseed crops without manual labor.

How It Works: Mode of Action
Hachiman uses a "Dual Action" technology that hits weeds in two different ways, ensuring they cannot survive:
- Stops Lipid Synthesis (Quizalofop): Rapidly absorbs into grassy weeds and stops them from producing essential fats (lipids). This halts growth within 48 hours and causes the "Dead Heart" symptom in grasses.
- Stops Protein Production (Imazethapyr): Blocks the production of vital amino acids in broadleaf weeds and sedges. This slowly starves the weed, turning leaves red or purple and killing the plant completely.
- Deep Root Kill: The chemical travels down to the roots and underground tubers (especially in Motha), destroying the weed from the bottom up to prevent regrowth.
Result: Weeds stop growing in 2 days and die completely within 14-21 days.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Soybean & Groundnut |
Grasses: Barnyard Grass (Sawan), Crowfoot Grass (Makra), Crabgrass. Broadleaf: Tropical Spiderwort (Kena/Kankawa), False Amaranth (Lahsua), Carpet Weed (Santhi). Sedges: Purple Nutsedge (Motha). |
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 | 175 ml Hachiman + 175 ml H-Mix | 80 - 100 L | ~2 ml (+ 2 ml H-Mix) | 60-75 |
| Groundnut | 175 ml Hachiman + 175 ml H-Mix | 80 - 100 L | ~2 ml (+ 2 ml H-Mix) | 60-75 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing (The Golden Window): Apply between 15 to 25 Days After Sowing (DAS). Weeds should be in the 2 to 4 leaf stage. Do not apply on mature weeds (flowering stage).
- Mixing: Always mix the provided H-Mix Adjuvant. This is crucial for sticking the medicine to waxy weed leaves and ensuring it isn't washed away by rain.
- Coverage & Moisture: Ensure there is sufficient soil moisture (Wattar condition) before spraying. Use a Flat Fan or Flood Jet nozzle for uniform coverage. Avoid spraying on drought-stressed crops.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Does Hachiman kill Motha (Nutsedge)?
Yes. The Imazethapyr component in Hachiman is highly effective against sedges like Motha (Cyperus rotundus). It travels to the underground tubers to prevent regrowth.
2. What is the best time to spray Hachiman?
The best time is when the weeds are small (2-4 leaves), which usually happens 15-25 days after sowing the crop. Spraying too late reduces effectiveness.
3. My crop turned slightly yellow after spraying. Is this normal?
Yes, this is called "Yellow Flash." It is temporary. As long as your soil has moisture, the crop will recover its green color and growth within 7-10 days with no yield loss.
4. What if it rains after spraying?
Hachiman (with H-Mix) is rain-fast within 1-2 hours. If it rains after this period, you do not need to respray.
5. Can I plant Wheat or Gram (Chickpea) in the next season?
Yes. Wheat, Gram, and Mustard are generally safe to plant in the Rabi season following Hachiman use, provided there was normal rainfall during the Kharif season to break down the residues.
