PI Industries Pimix Herbicide (Metsulfuron Methyl + Chlorimuron Ethyl)
The expert solution for controlling tough sedges and broadleaf weeds in Rice.
Pimix Herbicide is a powerful, low-dose weed control solution designed specifically for modern rice farmers. Whether you practice Transplanted Rice or Direct Seeded Rice (DSR), Pimix effectively targets the "sedge-broadleaf" complex that many standard herbicides miss.
Powered by PI Industries, it uses advanced dual-action chemistry to stop weeds from the inside out, ensuring your crop gets all the nutrition it deserves.

How It Works: Mode of Action
Pimix works systemically, meaning it travels inside the plant to kill it completely from leaf to root.
- Absorption: The herbicide is absorbed through the leaves (foliage) and roots of the weeds.
- Inhibition: It blocks the ALS enzyme, which is responsible for producing essential amino acids needed for plant growth.
- Elimination: Cell division stops immediately. The weed turns yellow, then brown, and dies completely within 14–21 days.
Note: While visual death takes time, the weeds stop competing with your crop almost immediately after spraying.

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 (Pre-Emergence) | 8g Sachet (Mix with Sand) | - | - | As per Label |
| Rice (Post-Emergence) | 8g Sachet | 200 Litres | - | As per Label |
| Direct Seeded Rice (DSR) | 8g Sachet | 200 Litres | - | As per Label |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Refer to product leaflet for specific rotational crop waiting periods.
How to Apply: Best Practices
- Timing: For Pre-emergence, apply 0-5 days after transplanting. For Post-emergence, apply 15-25 days after planting (2-4 leaf stage of weeds).
- Mixing: For Pre-emergence, mix the 8g sachet with 10-20kg of dry sand or fertilizer and broadcast. For Post-emergence, mix with water and spray.
- Coverage: If spraying, drain the field before application to expose weeds. Re-flood the field after 24-48 hours.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Does Pimix control grass weeds?
Pimix is mainly for sedges and broadleaf weeds. For complete control including grasses, it is often tank-mixed with Bispyribac Sodium (e.g., Nominee Gold).
2. Can I plant any crop after using Pimix?
Be careful. Sensitive crops like Sunflower and Maize can be damaged by soil residues. Wheat is generally safe to plant after Rice. Check the label for waiting periods.
3. What is the pack size?
Pimix comes in a convenient 8-gram sachet, which is exactly one dose for one acre. This prevents overdosing.
4. What if it rains after spraying?
Pimix is rainfast in 4 to 6 hours. If it rains after this period, you do not need to spray again.
5. Can I use it on dry soil?
For Pre-emergence (broadcasting), a thin film of water (2-3 cm) is needed. For Post-emergence (spraying), moist soil is essential for the best results.
