Toptoo Fungicide (Carbendazim 12% + Mancozeb 63% WP)
Complete protection for your crops with the power of dual-action chemistry and essential micronutrients.
Toptoo by Nichino India is a superior "combipack" fungicide. It combines the curing power of Carbendazim with the protective shield of Mancozeb. Beyond just killing fungus, it nourishes your plants with Zinc and Manganese, resulting in a lush, green, and healthy crop.
Best For: Paddy (Rice), Groundnut, Chilli, Tea, Maize, and Potato.
Why Choose This Product? Key Benefits
- ⏱️Systemic & Contact Action: Works in two ways—it enters the plant to cure existing infections (Systemic) and covers the leaves to stop new fungus from entering (Contact).
- ?️Broad Spectrum Control: One solution for multiple problems. It effectively controls Blast, Leaf Spot, Rust, Blights, and Fruit Rots across many crops.
- ⏳Resilience Builder: Because it attacks fungus at multiple points, it prevents pests from developing resistance, ensuring the medicine keeps working year after year.
- ?️Excellent Rainfastness: Stays effective on the plant even if it rains 4 to 6 hours after spraying, saving you the cost of re-spraying.
- ?Phytotonic "Green" Effect: Enriched with Manganese (Mn) and Zinc (Zn), it boosts photosynthesis and makes leaves greener and healthier.

How It Works: Mode of Action
Toptoo uses a "Kick-back and Shield" strategy to manage diseases efficiently:
- Systemic Cure (Carbendazim): Absorbed by the roots and leaves, it moves upwards inside the plant. It stops the fungus from dividing cells (mitosis), effectively curing infections that are already inside the tissue.
- Contact Shield (Mancozeb): Remains on the leaf surface forming a toxic layer. When fungal spores land on the leaf, this layer stops them from germinating, preventing new infections.
- Nutritional Boost: The breakdown of Mancozeb releases Zinc and Manganese, which corrects micronutrient deficiencies and boosts the plant's natural immunity.

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 (gm / Acre) | Water (L / Acre) | Dose (gm / Litre) | PHI (Days) |
|---|---|---|---|---|
| Paddy (Rice) | 300 g | 200 L | 1.5 g/L | 10-14 |
| Chilli | 300 g | 200 L | 1.5 g/L | 10-14 |
| Groundnut | 200 - 250 g | 200 L | 1 - 1.25 g/L | 10-14 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply preventively or immediately at the first sign of disease spots. For Paddy, spray at booting to heading stages for best Neck Blast control.
- Mixing: Compatible with most insecticides and fungicides. Do NOT mix with alkaline substances like Bordeaux mixture or Lime Sulphur.
- Coverage: Ensure thorough coverage of the foliage. Use at least 200 liters of water per acre for field crops.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying near fish ponds.
Frequently Asked Questions
1. Is Toptoo curative or protective?
It is both! The Carbendazim component cures existing internal infections, while the Mancozeb component forms an external protective shield.
2. Can I use this on export crops?
While safe for India, be cautious with crops for export to the EU (like Basmati or Grapes) due to strict residue limits on Mancozeb/Carbendazim. Always check current MRLs.
3. What is the rainfast time?
Toptoo is generally rainfast within 4 to 6 hours after spraying.
4. Can I use it for seed treatment?
Yes, it is excellent for seed treatment (e.g., Groundnut) to control soil-borne rot. Use roughly 2.5g per kg of seed.
5. Why is it called a "Phytotonic" product?
It contains Zinc and Manganese, which are essential micronutrients. This helps the plant grow greener leaves and photosynthesize better, improving overall health.
