How It Works: Mode of Action
Gaintop contains Copper Oxychloride ($Cu_2(OH)_3Cl$), which acts as a multi-site inhibitor. It does not enter the plant but stays on the surface to kill spores on contact.
- Contact & Release: When mixed with moisture (rain or dew) and mild acidity on the leaf, Gaintop releases active Copper ions ($Cu^{2+}$).
- Multi-Pronged Attack: These ions attack the fungal cell wall, disrupt enzymes, and break down proteins essential for the fungus's life.
- Energy Blockade: It effectively shuts down the energy production (respiration) of the fungus, causing the spores to dry up and die immediately.
Note: Because it attacks so many parts of the fungus at once, pathogens cannot adapt or develop resistance to it.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Plantation Crops (Coffee, Tea, Cardamom) | Leaf Rust, Black Rot, Blister Blight, Red Rust, Clump Rot. |
| Fruit Crops (Grapes, Banana, Citrus, Mango) | Downy Mildew, Anthracnose, Sigatoka Leaf Spot, Citrus Canker. |
| Vegetables (Potato, Tomato, Chilli) | Early Blight, Late Blight, Leaf Spot, Fruit Rot, Damping Off. |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Application must be preventive (before disease spreads).
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Coffee | 1500 g | 300 - 400 L | 3.75 - 5.0 g | As required |
| Potato / Tomato | 1000 g | 300 - 400 L | 2.5 - 3.0 g | As required |
| Grapes / Chilli | 1000 g | 300 - 400 L | 2.5 - 3.0 g | As required* |
*PHI = Pre-Harvest Interval: For export grapes, stop spraying 30-40 days before harvest. For Mango, stop 10 days before harvest to avoid spotty residue.
How to Apply: Best Practices
- Timing: Spray preventively (before disease starts) or immediately upon noticing the first symptoms. Avoid spraying during full bloom/flowering to prevent flower drop.
- Mixing: Do not dump powder directly into the full tank. Make a "cream" (smooth paste) with a little water first, then add this to the tank while stirring.
- Coverage: Use Hollow Cone nozzles for a fine mist. Ensure full coverage of the leaf surface (both top and bottom).
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Is Gaintop compatible with other pesticides?
Yes, it is generally compatible with common insecticides (like Chlorpyrifos) and fungicides (Mancozeb, Sulphur).
WARNING: Do NOT mix with Lime Sulphur or highly acidic chemicals.
2. Can Gaintop cure a disease that has already spread?
Gaintop is primarily a protectant. It works best when applied before infection. For heavy existing infections, mix with a systemic fungicide like Cymoxanil or Metalaxyl for curative action.
3. Can I use Gaintop during flowering?
No. Copper can dry out pollen and cause flower drop. Avoid using it during the peak flowering stage of crops like Grapes and Mango.
4. Does it wash off easily in the rain?
No. Gaintop contains special sticking agents that make it "rainfast" once it dries. However, in heavy monsoon rains, adding a sticker/spreader is recommended.
5. Is it effective against bacteria?
Yes. Gaintop is one of the few products effective against bacterial diseases like Citrus Canker, especially when mixed with Streptocycline.
