Gozaru (Copper Oxychloride 50% WP) – Broad Spectrum Fungicide & Bactericide
The Ultimate "Double Action" Shield: Protects crops against both Fungal and Bacterial diseases.
Gozaru is a premium Copper Oxychloride 50% WP formulation designed for modern agriculture. Unlike older copper fungicides, Gozaru utilizes ultra-fine particle technology and a neutral pH formula. This makes it highly effective against tough diseases like Late Blight and Canker while being safe to mix with other pesticides. It acts as a powerful contact fungicide, creating a protective layer on your crops that prevents infection before it starts.
Best For: Potato, Tomato, Chillies, Citrus, and Grapes.
Why Choose This Product? Key Benefits
-
⏱️
Dual Action Power: Acts as both a Fungicide and a Bactericide, solving two problems with one spray.
-
🛡️
Neutral pH Advantage: Unlike acidic or alkaline generic coppers, Gozaru is neutral (~pH 7). This means you can tank-mix it with other insecticides without reducing their power.
-
⏳
Superior Coverage: Made with ultra-fine particles that spread evenly over the leaf, leaving no gap for fungus to enter.
-
🌧️
Rain-Fast Protection: Sticks firmly to the plant surface, providing long-lasting protection even during the monsoon season.
-
🌿
Resistance Fighter: Ideal for resistance management (IPM). It breaks the resistance cycle of tough pathogens like Late Blight.

How It Works: Mode of Action
Gozaru works as a preventative "Contact Fungicide." It stays on the leaf surface and acts like a minefield for disease spores.
- Contact & Release: When mixed with water and sprayed, copper particles stick to the leaves. Moisture (dew or rain) slowly releases active Copper ions ($Cu^{2+}$).
- Absorption: When a fungal spore or bacteria lands on the leaf, it absorbs these toxic copper ions.
- Destruction: The copper ions destroy the proteins and enzymes inside the pathogen, stopping energy production and killing the germinating spore instantly.
Note: Because it attacks multiple parts of the fungus, pests cannot easily develop resistance to Gozaru.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Potato & Tomato | Late Blight & Early Blight |
| Chillies | Fruit Rot (Anthracnose) & Leaf Spot |
| Citrus & Banana | Citrus Canker (Bacteria), Leaf Spot & Sigatoka |
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) |
|---|---|---|---|---|
| Potato / Tomato | 1000 g | 300 - 400 L | ~3.0 g | 14 Days |
| Chillies | 1000 g | 300 - 400 L | ~3.0 g | 14 Days |
| Citrus / Grapes | 1000 g | 400 L | 2.5 - 3.0 g | 14 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply strictly as a preventative measure (Prophylactic). Start spraying 30-45 days after sowing or immediately when weather becomes cloudy/humid.
- Mixing (Slurry Method): Do not dump the powder directly into the tank. Mix the required quantity with a small amount of water in a bucket first to make a smooth paste (slurry), then pour this into the spray tank.
- Coverage: Use a Hollow Cone nozzle for the best mist. Ensure you coat the undersides of the leaves where fungus hides.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Is Gozaru effective against bacteria?
Yes. Unlike most fungicides that only kill fungus, Copper Oxychloride is a powerful bactericide, making it effective against Citrus Canker and Bacterial Leaf Spots.
2. Can I mix Gozaru with other pesticides?
Yes. Because Gozaru has a neutral pH, it is compatible with many common insecticides and fungicides. However, avoid mixing it with highly alkaline products like Lime Sulphur.
3. When should I spray for Potato Late Blight?
Start spraying before the disease appears, typically when the crop canopy closes or during cloudy, wet weather. Repeat every 7-10 days.
4. Does it cure the disease if the plant is already infected?
Gozaru is primarily a protectant. It works best to prevent the disease from spreading to healthy leaves. For severe existing infections, mix it with a curative systemic fungicide.
5. What is the shelf life of the product?
When stored in a cool, dry place in its original unopened packaging, it typically has a shelf life of 2 years from the date of manufacture.
