Sikosa Herbicide: The Complete Weed Solution for Paddy
Unlock higher rice yields with the advanced power of Banyan Technology™.
Sikosa by Crystal Crop Protection is a revolutionary broad-spectrum herbicide designed specifically for transplanted rice. It tackles the toughest challenge in paddy farming: the "Critical Period of Weed Control" (first 30-45 days).
By combining two powerful active ingredients—$Pretilachlor$ and $Bensulfuron\ Methyl$—in a stable Oil Dispersion (OD) formulation, Sikosa offers a "Double-Lock" defense against grasses, sedges, and broadleaf weeds.

How It Works: Mode of Action
Sikosa employs a dual-action mechanism to "double-lock" weed growth, preventing resistance and ensuring total cleanup.
- Cell Division Inhibition ($Pretilachlor$): It forms a chemical barrier at the soil-water interface. Absorbed by shoots, it stops cell division, killing grassy weeds before they emerge.
- Amino Acid Blockade ($Bensulfuron\ Methyl$): This systemic component moves through the roots and leaves to stop the production of essential amino acids (ALS inhibition), effectively starving sedges and broadleaf weeds.
- Synergistic Oil Delivery: The unique OD formulation acts as a built-in adjuvant, improving spreading on water and sticking to weed surfaces for maximum uptake.
Result: Weeds stop growing within hours and die completely within a few days.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Transplanted Rice (Paddy) | Barnyard Grass (Echinochloa crus-galli), Jungle Rice |
| Transplanted Rice (Paddy) | Rice Flat Sedge (Cyperus iria), Umbrella Sedge |
| Transplanted Rice (Paddy) | Water Primrose (Ludwigia), False Daisy (Eclipta alba) |
Recommended Dosage & Application
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) |
|---|---|---|---|---|
| Transplanted Rice | 500 ml | 200 - 250 L | 2 - 2.5 ml | As per Label |
| Direct Seeded Rice (Wet) | 500 ml | 200 - 250 L | 2 - 2.5 ml | As per Label |
| -- | -- | -- | -- | -- |
*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 strictly between 0 to 3 Days After Transplanting (DAT). Early application is critical for pre-emergence success.
- Mixing: SHAKE WELL before use. The OD formulation requires vigorous shaking to re-suspend the active ingredients in the oil carrier.
- Coverage: Maintain 2-3 cm of standing water in the field for 5-7 days after application. This water acts as a vector to spread the chemical evenly.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid draining treated water into fish ponds.
Frequently Asked Questions
1. Can I use Sikosa after 10 days of transplanting?
No. Sikosa is a pre-emergent herbicide. It works best when applied within 0-3 days. For older weeds, a post-emergent herbicide like Bispyribac Sodium is required.
2. Is Sikosa effective against sedges like Motha (Cyperus)?
Yes. The Bensulfuron Methyl component in Sikosa is a specialist for sedges and broadleaf weeds, offering superior control compared to plain Pretilachlor.
3. Can I mix Sikosa with sand and broadcast it?
While common with granules, Sikosa is a liquid OD formulation. For best results and uniform coverage, spraying using a knapsack sprayer with a flood-jet nozzle is recommended.
4. What happens if it rains after spraying?
Sikosa uses oil-dispersion technology which improves rainfastness. The oil helps the chemical bind to the soil and weeds better than standard water-soluble powders.
5. Is it safe for fish?
Pretilachlor can be toxic to aquatic life. Do not drain treated water into aquaculture ponds or natural water bodies immediately after application.
