Gaintop Fungicide (Copper Oxychloride 50% WP)
The Ultimate "Gromor Suraksha" Shield Against Fungus and Bacteria
Gaintop by Coromandel International is a powerful, broad-spectrum contact fungicide and bactericide. Formulated with Copper Oxychloride (50% w/w), it provides a strong protective barrier on your crops. Unlike standard copper salts, Gaintop is engineered with specific sticking agents to ensure it stays on the leaf longer, even during rains.
Best For: Controlling tough diseases like Downy Mildew, Late Blight, Leaf Rust, and Bacterial Canker in plantation and vegetable crops.
Why Choose This Product? Key Benefits
- ⏱️Long-Lasting Protection: Stays active on the plant surface for 10 to 14 days, reducing the need for frequent re-spraying.
- ?️Dual Action Defense: Acts as both a fungicide and a bactericide (kills bacteria), making it perfect for complex infections like Citrus Canker.
- ⏳Prevents Resistance: As a multi-site inhibitor, pests cannot easily develop resistance to Gaintop, keeping it effective year after year.
- ?️Superior Rainfastness: Contains high-quality wetting agents that help the spray stick to waxy leaves like Banana and Coffee.
- ?Smart Release Technology: Releases active copper ions only when acidity rises (due to fungal attack or rain), ensuring safety for the plant.

How It Works: Mode of Action
Gaintop acts as a "shield" on the leaf surface. It utilizes a sophisticated equilibrium mechanism to release copper ions exactly when needed.
- Contact & Adhesion: When sprayed, the particles adhere firmly to the leaf surface due to special sticking agents.
- Activation: When fungal spores or bacteria try to attack (releasing acid), Gaintop releases active Copper ions ($Cu^{2+}$).
- Elimination: These copper ions destroy the pest's cell walls and block their energy production (respiration), killing them instantly.
Note: Because it attacks multiple parts of the fungus, it is nearly impossible for diseases to build resistance against Gaintop.

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) |
|---|---|---|---|---|
| Vegetables (Potato, Tomato, Chilli) | 1000g (1 kg) | 300 - 400 L | 2.5g - 3g | 7 - 14 |
| Plantations (Coffee, Cardamom) | 1500g (1.5 kg) | 300 - 400 L | 3.5g - 4g | As Required |
| Fruits (Grapes, Citrus, Banana) | 1000g (1 kg) | 300 - 400 L | 2.5g | 10 - 20 (Strict) |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting to ensure food safety.
How to Apply: Best Practices
- Timing: Apply protectively before the disease spreads (e.g., pre-monsoon for Coffee). Avoid spraying during full flowering (can cause flower drop) or extreme heat.
- Mixing (The "Creaming" Method): Do not dump powder directly into the full tank. Mix Gaintop with a little water in a bucket first to make a smooth paste or "cream," then add this to your spray tank.
- Coverage: Use Hollow Cone nozzles for a fine mist. Ensure full coverage of the leaf (top and bottom), as Gaintop only protects where it lands.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Toxic to fish—do not use near water bodies.
Frequently Asked Questions
1. Can I mix Gaintop with antibiotics?
Yes. For bacterial diseases like Citrus Canker, it is standard practice to mix Gaintop with Streptocycline for better results.
2. Is Gaintop a systemic fungicide?
No, Gaintop is a contact fungicide. It stays on the outside of the plant to kill spores before they enter. It does not travel inside the plant sap.
3. What can I NOT mix with Gaintop?
Do not mix with Lime Sulphur, highly acidic substances (like Phosphoric acid), or certain plant growth regulators (PGRs).
4. Can I use it on flowering crops?
Use with caution. Copper can damage delicate flowers or cause "russeting" on young fruit skin. Avoid spraying during peak bloom.
5. Does it control algae?
Yes, Gaintop is excellent for controlling Red Rust (an algal disease) on Tea and fruit trees.
Safety & Disclaimer
