How It Works: Mode of Action
Roko operates on a unique fungitoxic mechanism that stops disease at the cellular level.
- Absorption: Upon spraying or dipping, the active ingredient is rapidly absorbed by the plant's roots or leaves.
- Translocation: It travels upward through the plant (xylem), turning into Carbendazim (the active fungus killer) inside the tissue.
- Eradication: It disrupts the fungal cell division (mitosis) by binding to Beta-tubulin, effectively stopping the fungus from growing and spreading.
Note: This systemic nature makes it excellent for hidden infections but ineffective against Oomycetes (like downy mildew).

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 (g / Acre)* | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Paddy / Cereals | 200 - 300 g | 200 L | 1 - 1.5 g | 14+ Days |
| Vegetables (Tomato/Chili) | 200 - 300 g | 150 - 200 L | 0.5 - 1 g | 5 - 7 Days |
| Fruits (Apple/Grapes) | Varies (High Volume) | As required | 0.5 g | 3 - 14 Days |
*Note: Product is a powder, so dosage is in Grams (g). Use 2-3g/kg for Seed Treatment. PHI = Pre-Harvest Interval.
How to Apply: Best Practices
- Timing: Apply preventively (before disease starts) or immediately at the first sign of spots or rot for the best "Curative" results.
- Mixing: Perform a "Jar Test" first. Do NOT mix with highly alkaline substances (like lime) or Copper fungicides, as they reduce efficacy.
- Coverage: Ensure uniform spray coverage. For Seed Treatment (ST) or Seedling Dip, follow the specific ratios to protect roots from soil-borne fungi.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
