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.
Frequently Asked Questions
1. Does Roko control root rot and wilt?
Yes, Roko is highly effective against Fusarium Wilt
and Root Rot. It can be used as a seed treatment, seedling dip, or

Absolutely. Treating seeds with Roko (2–3g per kg)
protects the crop from seed-borne and soil-borne diseases right
from germination.
3. Is Roko safe for all crops?
Roko is safe for most crops including paddy, pulses,
vegetables, and fruits. However, exercise caution with very young
seedlings and avoid overdose.
4. Can I mix Roko with other fungicides?
Yes, but avoid mixing with alkaline products or
copper. To prevent resistance, it is recommended to mix Roko with
a contact fungicide (like Mancozeb).
