Copper Oxychloride Fungicide 25kg – Broad-Spectrum Disease Control for Fruit, Veg & Ornamentals

Copper Oxychloride Fungicide 25kg: Broad-Spectrum Disease Control for Fruit, Veg & Ornamentals

Copper Oxychloride is a broad-spectrum protectant fungicide and bactericide containing 500 g/kg copper oxychloride. It's a long-standing, economical choice for controlling a wide range of fungal and bacterial diseases across fruit and vegetable crops, citrus, stone fruit, pome fruit and ornamentals, and it's used by home gardeners and horticulturists right across Australia.

It's a Group M1 multi-site fungicide, which means it works as a protective contact spray rather than a systemic one. Once applied, it forms a fine copper film over the plant surface that stops disease spores and bacteria before they can establish. Because it protects the surface rather than curing infection inside the plant, timing and thorough coverage matter, and it's most effective used preventively.

What It Controls

Copper oxychloride controls a broad list of fungal and bacterial diseases, including peach leaf curl, freckle, brown rot and black spot on stone fruit, leaf spots, early and late blight, downy mildew, rust, anthracnose, and bacterial diseases such as citrus canker and bacterial leaf spot. It suits fruit trees, citrus, grapes, vegetables such as tomatoes and potatoes, roses and other ornamentals.

How to Use

Copper oxychloride is a water-dispersible powder. Mix it with water and stir thoroughly, then spray evenly over the plant so all surfaces, including the undersides of leaves, are covered. As a general home-garden guide, mixing rates range from about 30 to 75 g per 10 L of water depending on the crop and disease, but always follow the rates on the product label for your specific situation.

Apply at the first sign of disease or as a preventative, and reapply every 7 to 14 days depending on weather and disease pressure. Since it's a contact product, it washes off, so reapply after rain. For stone fruit diseases like leaf curl, apply as a semi-dormant spray at bud swell before the buds open. Avoid spraying in extreme heat, when rain is expected within 24 hours, or onto stressed plants.

Important: Avoiding Plant Damage

Copper sprays can cause leaf and fruit damage (phytotoxicity) if over-applied, particularly on citrus and during cool, wet conditions. Stick to the label rate, don't increase the frequency or concentration, and ensure good coverage rather than heavy dosing. Copper also builds up in soil over time and is toxic to aquatic life, so avoid run-off into drains and waterways.

Safety

Wear gloves and protective clothing when mixing and applying, avoid inhaling the dust or getting it in your eyes or on skin, and wash your hands thoroughly after use. Store in a cool, dry place out of direct sunlight, away from children and pets. Read the full label before use and follow all directions and rates.

Frequently Asked Questions

What is the active ingredient in copper oxychloride fungicide?
It contains 500 g/kg copper oxychloride, a Group M1 multi-site protectant fungicide that also controls many bacterial diseases.

What diseases does copper oxychloride control?
A broad range, including peach leaf curl, freckle, brown rot, black spot, leaf spots, early and late blight, downy mildew, rust, anthracnose, and bacterial diseases like citrus canker and bacterial leaf spot.

What is the mixing rate for copper oxychloride?
For home garden use, rates generally range from about 30 to 75 g per 10 L of water depending on the crop and disease. Always follow the specific rate on the product label for your situation.

Is copper oxychloride suitable for fruit trees and vegetables?
Yes. It's used on fruit trees, citrus, grapes, vegetables such as tomatoes and potatoes, and ornamentals, for both preventing and controlling disease.

How often should I apply it?
Apply at the first sign of disease or as a preventative, roughly every 7 to 14 days depending on weather and disease pressure. As a contact fungicide it washes off, so reapply after rain.

When should I not use copper oxychloride?
Avoid applying in extreme heat, when rain is forecast within 24 hours, or to stressed plants. Don't over-apply, as copper can cause leaf and fruit damage, especially on citrus in cool, wet conditions.

Does copper oxychloride work as a preventative or a cure?
It's a protectant, so it works best preventively by stopping spores and bacteria before they infect. It doesn't cure disease already inside the plant, which is why coverage and timing are important.

What sizes does it come in?
 It's available in 1kg, 2kg, 4kg and 25kg, with the 25kg pack suited to orchards, larger gardens and commercial growers.
