Monomi Herbicide (Pyroxasulfone 85% WG) – The Ultimate Solution for Resistant Weeds
Stop Gulli Danda (Phalaris minor) before it starts. Experience advanced Japanese technology for a weed-free harvest.
Monomi (by IFFCO-MC) is a revolutionary pre-emergence herbicide designed to tackle the toughest weeds in Wheat, Maize, and Soybean. Its active ingredient, Pyroxasulfone, breaks the resistance cycle, offering effective control against weeds that no longer respond to older chemicals like Clodinafop or Sulfosulfuron.
Best For: Farmers facing heavy resistance issues with Phalaris minor (Mandusi/Gulli Danda) in wheat fields.
Why Choose This Product? Key Benefits
-
⏱️
Early Action: Kills weeds right at germination (0-3 days), ensuring your crop grows without competition from day one.
-
🛡️
Resistance Breaker: Specifically formulated to kill "Super Weeds" (like resistant Gulli Danda) that survive other sprays.
-
⏳
Long-Lasting Control: Stays active in the soil to prevent late-flushing weeds, keeping fields clean for longer.
-
🌧️
Low Volatility: Does not evaporate easily from the soil surface, making it stable even if temperatures are slightly high at sowing.

How It Works: Mode of Action
[Image of pyroxasulfone mode of action diagram]Monomi works by inhibiting the biosynthesis of Very Long Chain Fatty Acids (VLCFA), which are essential for cell division.
- Absorption: The herbicide is absorbed by the roots and emerging shoots (coleoptiles) of the weed.
- Growth Stop: It blocks cell division in the weed seedling, preventing it from growing.
- Elimination: The weed seedling dies before it can even break through the soil surface, resulting in a clean field.
Note: This mechanism is different from older herbicides, which is why it kills weeds that have developed resistance to other chemicals.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Wheat | Phalaris minor (Gulli Danda), Rumex dentatus (Jangli Palak) |
| Maize | Echinochloa (Barnyard grass), Eleusine indica (Goosegrass) |
| Soybean | Echinochloa colona, Carpet weed, Amaranthus spp. |
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/g per Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Wheat | 60 g | 200 L | 0.3 g | -- |
| Maize | 60 g | 200 L | 0.3 g | -- |
| Soybean | 60 g | 200 L | 0.3 g | -- |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Use 200 Litres of water strictly for best results.
How to Apply: Best Practices
- Timing: Apply strictly within 0 to 3 days of sowing (Pre-emergence). Do not apply after weeds have emerged.
- Mixing: Dissolve the granules in a small amount of water first, then fill the tank. Use 200 Liters of water per acre to create a continuous film over the soil.
- Coverage: Use a Flat Fan or FloodJet nozzle for uniform spraying. Ensure the field is clod-free and moist.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid inhalation of dust.
Frequently Asked Questions
1. Can I use Monomi on Durum Wheat?
No. Do not use Pyroxasulfone on Durum Wheat varieties as it can cause crop damage. It is safe for standard commercial wheat varieties.
2. Why do I need 200 Liters of water?
Monomi works by creating a chemical film on the soil surface. Using less water (like 100L) leaves gaps where weeds can grow. 200L ensures complete coverage.
3. What if I spray after 3 days?
Efficacy drops significantly. If the crop or weeds have already emerged, Monomi will not be effective and may damage the crop. Stick to the 0-3 day window.
4. Can I mix Monomi with other herbicides?
Yes, for resistance management, it can be tank-mixed with Pendimethalin. Always check compatibility and perform a jar test first.
5. Is Monomi safe for the next crop?
Generally, yes for standard rotations like Rice-Wheat. However, caution is advised for sensitive vegetable crops planted immediately after harvest.
