Barmac Copper Oxychloride 2kg – Broad-Spectrum Fungicide for Fruit, Veg & Ornamentals

Barmac Copper Oxychloride 2kg: Broad-Spectrum Fungicide for Fruit, Veg & Ornamentals

Barmac Copper Oxychloride is a broad-spectrum protectant fungicide and bactericide for controlling a wide range of fungal and bacterial diseases in fruit and vegetable crops, citrus, stone fruit, pome fruit and ornamentals. It contains 500 g/kg copper oxychloride and is a Group M1 fungicide, offering economical, reliable disease control across the garden and orchard. This is the 2kg pack.

It's a green powder that's pH neutral with an ultra-fine particle size, the majority of particles being 2 microns or less in diameter. That fine grind is what makes it free-flowing and easy to mix and apply, giving good coverage and adhesion on the plant surface.

How It Works

As a Group M1 protectant, copper oxychloride works as a contact fungicide rather than a systemic one. It forms a fine copper film on the plant surface that stops fungal spores and bacteria from establishing, so it protects the plant rather than curing existing infection. That means it's most effective applied preventively, before disease appears, and with thorough coverage including the undersides of leaves. As a multi-site protectant, it also carries a low risk of resistance.

How to Use

Mix the powder with water, stir thoroughly, and spray evenly over the plant so all surfaces are covered. As a general home-garden guide, copper oxychloride is mixed at around 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 based 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.

It can be applied in tank mixes with a wide range of other chemicals and fertilisers, though use caution with alkaline products.

Important

Copper can cause leaf and fruit marking (phytotoxicity) if over-applied, particularly on citrus and in cool, wet conditions, so stick to the label rate and don't over-apply. Copper also builds up in soil over time and is toxic to aquatic life, so avoid run-off into drains and waterways. Wear gloves and eye protection when mixing and applying, avoid inhaling the dust, and wash your hands after use.

What is copper oxychloride used for?
It controls a broad range of fungal and bacterial diseases, including leaf spots, blights, downy mildew, rust, brown rot, black spot and leaf curl, on fruit trees, citrus, stone fruit, vegetables and ornamentals.
