Pimix Herbicide (Metsulfuron Methyl + Chlorimuron Ethyl)
The Ultimate Solution for Sedges and Broadleaf Weeds in Rice Farming
Pimix is a powerful, broad-spectrum herbicide designed specifically for modern rice cultivation. By combining two potent active ingredients, it effectively clears difficult weeds that standard grass herbicides leave behind.
Best for: Transplanted Rice, Direct Seeded Rice (DSR), and controlling tough sedges like Cyperus and broadleaf varieties.

- ⏱️Flexible Application Timing: Works effectively both as a Pre-Emergent (0–5 days) and Post-Emergent (15–25 days) spray.
- ?️Double Action Protection: Combines two active molecules to kill weeds through both leaves and roots for complete cleanup.
- ⏳Residual Soil Barrier: Prevents new weeds from germinating for weeks after application, keeping your field clean longer.
- ?️Weather Resistant: Rapidly absorbed by plants, becoming rainfast within just 4 to 6 hours after spraying.
- ?Low Dose Technology: High potency means you only need a tiny dose (8g per acre), reducing chemical load and cost.

How It Works: Mode of Action
Pimix works by targeting the specific enzymes weeds need to grow. It uses a "Systemic" action, meaning it moves inside the plant to kill it from the inside out.
- Absorption: The herbicide is quickly absorbed through the weed's leaves and roots.
- Inhibition: It blocks the ALS enzyme (Acetolactate Synthase), which stops the production of essential amino acids (Valine, Leucine, Isoleucine).
- Termination: Without these amino acids, cell division stops instantly. Weeds turn yellow, stop competing for nutrients, and die completely within 14–21 days.
Note: While death takes time, weed growth stops almost immediately after application.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Transplanted Rice | Rice Flatsedge (Cyperus iria), Umbrella Sedge (Cyperus difformis), False Daisy (Eclipta alba) |
| Direct Seeded Rice (DSR) | Hoorahgrass (Fimbristylis miliacea), Water Primrose (Ludwigia parviflora), Marsilea |
| Paddy (General) | Monochoria, Gooseweed, and other broadleaf/sedge complexes |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Overdosing can harm the crop.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice (Pre-Emergence) | 8 g | Standing Water | Mix with Sand | 60-90 |
| Rice (Post-Emergence) | 8 g | 200 L | 0.04 g | 60-90 |
| Direct Seeded Rice | 8 g | 200 L | 0.04 g | 60-90 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Always check the local label for exact PHI.
How to Apply: Best Practices
- Timing: Apply 0-5 days after transplanting (Pre-Em) OR 15-25 days after transplanting when weeds are at 2-4 leaf stage (Post-Em).
- Mixing: For Pre-Emergence, mix 8g with 10kg sand/fertilizer and broadcast. For Post-Emergence, mix with 200 Liters of water and spray.
- Coverage: If spraying, drain water from the field first to expose weeds. Re-flood the field 24-48 hours after spraying to stop new weeds.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Is Pimix safe for the next crop?
It is safe for Wheat and Rice rotations. However, avoid planting sensitive crops like Sunflower, Maize, or Vegetables immediately after harvest, as soil residues may affect them.
2. Can I mix Pimix with other herbicides?
Yes, Pimix is commonly tank-mixed with Bispyribac Sodium (e.g., Nominee Gold) to provide total control of grasses, sedges, and broadleaves in one shot.
3. Does it kill grassy weeds?
No, Pimix is a specialist for Sedges and Broadleaf weeds. It generally does not control grasses (Poaceae family).
4. What if it rains after spraying?
Pimix is rainfast within 4 to 6 hours. If it rains after this period, re-spraying is usually not required.
5. What is the pack size?
It comes in a pre-measured 8-gram sachet, which is the exact dose for one acre. This prevents dosing errors.
