Copper Oxychloride 50% WG

Copper Oxychloride 50% WG

Copper Oxychloride 50% WG is one of the oldest, most trusted, and most cost-effective fungicides used in Indian agriculture, with a history of disease control dating back to the original Bordeaux mixture farmers have relied on since the 1880s. As a copper-based contact fungicide, it stands out as one of the few products effective against both fungal and bacterial diseases together, making it a true all-rounder for crop protection.

How Copper Oxychloride 50% WG Works

When this fungicide comes into contact with moisture from dew, rain, or irrigation, it slowly releases copper ions that are toxic to fungal spores and bacterial cells. These copper ions work by denaturing proteins and enzymes within the pathogen’s cells, binding to sulfhydryl groups of certain enzymes and inactivating them, which prevents the fungus or bacteria from growing and reproducing. Because of its low solubility, the product gradually releases copper ions over time, giving extended, long-lasting protection rather than a single quick burst of activity.

Why Farmers Choose This Fungicide

One of the most valuable qualities of Copper Oxychloride 50% WG is its multi-site mode of action, which makes it exceptionally difficult for pathogens to develop resistance against it, even after decades of widespread global use. Its fine particle size allows it to stick firmly to leaves and plant surfaces, helping it withstand rain and remain effective during wet weather, which is exactly when fungal and bacterial diseases tend to spread fastest.

This fungicide is particularly valued for managing diseases that are difficult to control with regular fungicides alone, including bacterial wilt and rhizome rot in susceptible crops, along with downy mildew, early and late blight, leaf spots, fruit rots, and citrus canker across a wide range of fruit and vegetable crops. Because copper also supplies a trace nutrient to the plant, many farmers notice bolder, denser, and thicker foliage following application, alongside its primary disease control benefits. Being manufactured from a naturally occurring mineral, it is also considered safer for mammals compared to many synthetic fungicide options.

Key Benefits

• Controls both fungal and bacterial diseases together
• Effective against downy mildew, blight, leaf spot, and fruit rot
• Multi-site action makes resistance development very difficult
• Long-lasting residual protection, even in wet weather
• Supplies trace copper nutrition, supporting bolder foliage
• Rain-fast formulation that adheres well to plant surfaces
• Compatible with many other pesticides and fertilizers

Why Crop Nutrition Matters Alongside Disease Control

Crops protected from fungal and bacterial disease grow best when also given strong overall nutritional support. Products like Humic Acid 98% Flakes help build a stronger root system to support healthy recovery, while Power PGR Liquid helps the plant channel its renewed health into better flowering and fruit setting through the rest of the season.

Safety Tips & Precautions

• Apply as a preventive spray before disease symptoms appear, since it does not penetrate plant tissue
• Wear gloves, mask, and protective clothing while mixing and spraying
• Avoid direct contact with skin and eyes during application
• Do not mix with strongly alkaline products unless a compatibility test has been done first
• Repeat spraying at shorter intervals during continuous rainy weather
• Maintain the recommended pre-harvest interval before harvesting for market
• Wash hands and equipment thoroughly after spraying
• Keep away from children, animals, and food or feed storage areas

Storage Instructions

Store Copper Oxychloride 50% WG in a cool, dry place away from direct sunlight and moisture. Keep the container tightly sealed and out of reach of children and animals.
