FungicidesString Fungicide (Mancozeb 75% WP) by Nichino India
Advanced Japanese technology for broad-spectrum disease protection and visibly greener crops.
String is a premium contact fungicide brought to you by Nichino India (a subsidiary of Nihon Nohyaku Co., Ltd., Japan). Unlike standard fungicides, String uses a high-quality Mancozeb 75% WP formulation that acts as a powerful shield against a wide range of fungal diseases.
It doesn't just protect your crop; it feeds it. Enriched with Zinc (Zn) and Manganese (Mn), String provides a "Phytotonic Effect," turning leaves lush green and boosting overall plant health while preventing profit-robbing diseases like Blast, Blight, and Rust.

Product scienceHow It Works: Mode of Action
String works as a Multi-Site Contact Fungicide. It does not enter the plant system; instead, it forms a protective coating on the leaf surface.
- Enzyme Inhibition: It releases isothiocyanates that target and shut down critical enzymes within the fungal cell.
- Energy Blockade: It stops the fungus from producing ATP (energy), effectively starving the pathogen.
- Spore Prevention: It prevents fungal spores from germinating on the leaf, stopping the disease before it enters the plant.
Note: Because it is a contact fungicide, full coverage of the foliage is essential for success.

How to applyDosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
How to applyDosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (gm / Acre) | Water (L / Acre) | Dose (gm / Litre) | PHI (Days) |
|---|---|---|---|---|
| Paddy & Wheat | 600 - 800 g | 200 L | 3 - 4 g | 25 - 30 |
| Potato & Tomato | 600 - 800 g | 200 L | 3 - 4 g | 3 - 7 |
| Chilli & Vegetables | 600 - 800 g | 200 L | 3 - 4 g | 5 - 10 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note: Dosage is in grams (g) as String is a Wettable Powder.
Useful detailsHow to Apply: Best Practices
- Timing: Apply as a preventive measure (before disease appears) or at the very first sign of spotting. Repeat every 7-10 days if weather is cloudy/wet.
- Mixing: Use the "WALES" method. Dissolve the String powder in a bucket of water first before adding it to the main tank. It mixes well with most pesticides but do not mix with alkaline products like Bordeaux mixture.
- Coverage: Ensure complete coverage of the upper and lower leaf surfaces. String only protects the parts of the plant it touches.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.

Frequently Asked Questions
1. Does String cure the disease once it has spread?
No, String is primarily a preventive fungicide. It stops the disease from entering the plant. For established infections, mix String with a curative (systemic) fungicide for best results.
2. Why do farmers call it a "Phytotonic" product?
Because it contains Zinc and Manganese. These micronutrients are absorbed by the leaves, making the crop look greener and healthier, much like a mild fertilizer application.
3. Can I use String on all crops?
It is registered for many crops like Rice, Wheat, and Potato. However, do not use it on Jowar or Guava due to government regulations.
4. Is it safe for bees and beneficial insects?
Yes, String has a "Green Label" (Slightly Toxic) and is generally safer for beneficial insects compared to harsh chemical sprays, making it good for IPM (Integrated Pest Management).
5. What is the shelf life of the mixture?
Once mixed with water, the solution should be sprayed immediately. Do not keep the mixed solution overnight as it loses effectiveness.
