Almix® Herbicide: The Specialist for Broadleaf & Sedge Control in Rice
Stop weeds from stealing your yield with the power of dual-action Sulfonylurea technology.
Weeds compete aggressively with your paddy for sunlight, water, and fertilizers, potentially reducing your harvest by up to 50%. Almix® Herbicide (Metsulfuron-methyl + Chlorimuron-ethyl) is a modern, low-dose solution designed specifically for Asian rice farming. It targets difficult broadleaf weeds and stubborn sedges that ordinary grass-killers miss.
Best For: Farmers seeking a cost-effective, labor-saving alternative to manual weeding in transplanted or direct-seeded rice.
Why Choose Almix? Key Benefits
-
⏱️
Rapid Growth Stop: Weeds stop growing almost immediately after spraying, meaning they stop stealing nutrients from your crop within hours.
-
🛡️
Double Action Power: It works two ways—killing existing weeds through the leaves (contact) and preventing new seeds from sprouting via the soil (residual).
-
⏳
Long-Duration Control: One application provides lasting protection during the "Critical Period" (first 30–45 days), keeping your field clean until the rice canopy closes.
-
🌧️
Reliable Rainfastness: Once absorbed (typically within 2–6 hours), the medicine stays inside the plant and won't wash away with rain.
-
🌿
Safe for Rotation: It breaks down naturally in the soil, making it safe for planting Wheat, Maize, Vegetables, or Mustard in the next season.

How It Works: Mode of Action
Almix operates on a cellular level to stop weed growth instantly. Here is the 3-step process:
[Image of systemic herbicide translocation in plants]- Absorption: The herbicide is absorbed through the leaves (foliar) and the roots (soil), ensuring total coverage even if you miss a few leaves.
- Systemic Movement: The active ingredients travel through the plant's sap to the growing points (tips of roots and shoots).
- Enzyme Block: It inhibits the ALS enzyme, which weeds need to make proteins. Without proteins, cell division stops, and the weed dies within 1–3 weeks.
Note: You will see weeds turn yellow (chlorosis) within a week, followed by browning and death.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Transplanted Rice |
Sedges: Rice Flatsedge (Cyperus iria), Purple Nutsedge, Umbrella Sedge. Broadleaves: False Daisy, Gooseweed, Marsilea, Ludwigia. |
| Direct Seeded Rice (DSR) | Controls the same complex of Sedges and Broadleaf weeds efficiently. |
| Important Note | Almix does not kill grasses (like Barnyard grass). Use a tank mix for grass control. |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. This is a low-dose product; precision is key.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice (Paddy) | 8 grams | 120 - 150 Litres | approx. 0.06g | As per Label |
| Surfactant | 250 ml | N/A | ~2 ml | - |
| Note | Do not reduce water volume. Good coverage is essential for small weeds. | |||
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
[Image of farmer spraying herbicide in paddy field]- Timing: Apply as a "Post-Emergence" spray, generally 20–25 days after transplanting or sowing. The weeds should be in the 2–4 leaf stage (young and actively growing).
- Mixing: Dissolve the 8g packet in a bucket of water first to create a stock solution. Then, add this mixture to your sprayer tank. Add a surfactant (sticker) to help the medicine stick to waxy sedge leaves.
- Coverage: Before spraying, drain excess water from the field so the weed leaves are exposed. Keep soil moist/saturated. You can re-flood the field 2–3 days after spraying.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Will Almix kill grassy weeds like Barnyard grass?
No. Almix is specialized for Broadleaves and Sedges. For grasses, you must mix it with a grass-killer like Bispyribac-sodium.
2. Is it safe for the next crop?
Yes. The chemicals break down safely in the soil. Crops like wheat, maize, or vegetables grown in the next season will not be affected.
3. Can I use it if it is about to rain?
It is best to spray when no rain is expected for at least 6 hours. However, it is generally rainfast after 2 hours.
4. What nozzle should I use?
Use a Flat-fan or Flood-jet nozzle. Do not use hollow-cone nozzles (used for insecticides) as they create too much mist and drift.
5. Can I mix it with insecticides?
Yes, Almix is generally compatible with common rice insecticides like Fipronil or Chlorpyriphos, allowing you to treat weeds and pests in one go.
