Roko Fungicide (Thiophanate Methyl 70% WP)
The Ultimate Systemic Shield: Preventive, Curative, and Restorative Crop Protection
Roko Fungicide is a broad-spectrum systemic fungicide trusted by farmers for its unique "Triple Action" formula. Whether you are battling Scab in apples, Blast in paddy, or Wilt in vegetables, Roko works from the inside out. It is absorbed by the plant to provide long-lasting defense against soil-borne and seed-borne diseases, while simultaneously boosting plant health (phytotonic effect) for a greener, higher-quality harvest.
Best For: Controlling Powdery Mildew, Anthracnose, Fusarium Wilt, and Scab in fruits, vegetables, and cereals.
Why Choose This Product? Key Benefits
-
⏱️
Triple Action Formula: Acts as a Systemic (moves inside), Preventive (stops new infection), and Curative (heals existing disease) solution.
-
🛡️
Broad Spectrum Control: One product effectively targets multiple fungal threats like Anthracnose, Cercospora Leaf Spot, Powdery Mildew, and Root Rot.
-
⏳
Long-Lasting Defense: Because it is absorbed into the plant's system (xylem), it protects new leaves and shoots that grow after spraying.
-
🌧️
Quick Rainfastness: Rapidly absorbed by plant surfaces within 1–2 hours, ensuring the rain doesn't wash away your investment.
-
🌿
Phytotonic Effect: Contains sulfur elements that actively boost chlorophyll production, leading to visibly greener leaves and better yields.

How It Works: Mode of Action
Roko targets the fungal cell division process, stopping the disease in its tracks.
- Systemic Absorption: Upon application, the active ingredient is absorbed by roots or leaves and travels upward through the plant's vascular system (xylem).
- Cell Division Inhibition: Inside the plant, it converts to Carbendazim, which disrupts the fungal cell's ability to divide (mitosis inhibition).
- Complete Eradication: This process halts the spread of the fungus into new tissue and kills existing infections.
Note: Because Roko works on a specific site (single-site action), it should be rotated with other fungicides to prevent resistance.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Paddy (Rice) | Blast, Sheath Blight |
| Vegetables (Chili, Tomato, Potato) | Powdery Mildew, Anthracnose, Fruit Rot, Wilt, Leaf Spot |
| Fruits (Apple, Grape, Papaya) | Scab, Anthracnose, Powdery 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 / Method | Dose (Total / Acre) | Water (L / Acre) | Dose (gm / Litre) | PHI (Days) |
|---|---|---|---|---|
| Foliar Spray (General) | 250 - 500 gm | 200 L | 0.5 - 1.0 gm | 3 - 14 |
| Seed Treatment | N/A | N/A | 2 - 3 gm / kg seed | N/A |
| Soil Drench / Dip | As needed | As needed | 2 - 4 gm / Litre | N/A |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply as a preventive measure or immediately at the first sign of disease. Repeat every 7–14 days depending on severity.
- Mixing: Do NOT mix with highly alkaline water (high pH) or copper fungicides. Always perform a physical jar test before tank mixing.
- Coverage: Ensure full coverage of foliage. For post-harvest treatment, dip produce and dry in the shade to avoid heat degradation.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Is Roko effective against Wilt and Root Rot?
Yes. Because Roko is systemic, applying it as a soil drench or seed treatment allows it to enter the roots and control internal vascular diseases like Fusarium Wilt.
2. Does Roko make plants greener?
Yes. Roko contains sulfur elements that produce a "Phytotonic Effect," enhancing chlorophyll production and making leaves visibly greener and healthier.
3. Can I mix Roko with other chemicals?
Roko is compatible with most insecticides and fungicides, but it should never be mixed with Copper compounds or highly alkaline fertilizers (like lime sulfur).
4. What is the waiting period (PHI) for vegetables?
The typical Pre-Harvest Interval (PHI) for vegetables like Tomato or Bottle Gourd is generally 5 to 7 days, but always check the specific label for your region.
5. Is Roko safe for the applicator?
Roko carries a "Green Label," meaning it has low mammalian toxicity. However, standard protective gear (mask, gloves) is strictly recommended during spraying.
