Redox Products We Stock

Sulphate of Ammonia

Redox Sulphate of Ammonia is a fast-acting nitrogen fertiliser with about 20.5% nitrogen and 24% sulphur. It greens up tired lawns and pushes leafy growth in vegetables. It also gradually lowers soil pH, making it a good choice for alkaline soils and acid-loving plants such as azaleas, camellias and blueberries.

Epsom Salts (Magnesium Sulphate)

Epsom salts are a fully soluble source of magnesium and sulphur. They correct magnesium deficiency, which shows as yellowing between the leaf veins on citrus, tomatoes, roses and palms. Dissolve them in water for a fast-acting foliar spray, or apply them to the soil.

Copper Oxychloride Fungicide

Copper oxychloride is a broad-spectrum protectant fungicide and bactericide containing 500g/kg copper oxychloride. It helps prevent peach leaf curl, blight, downy mildew, rust and leaf spot on fruit trees, citrus, vegetables and ornamentals. Apply it before disease takes hold and always follow the label rates.

Sulphur Dust Powder

Sulphur dust powder is fine elemental sulphur used as a natural contact fungicide and miticide. Dust it over leaves to protect grapes, roses and cucurbits from powdery mildew, rust, black spot and mites. Worked into soil, it also lowers pH over time. It comes in 2kg and 4kg bags.

Borax Powder

Borax powder is sodium tetraborate decahydrate, a white, odourless mineral powder that dissolves in water. It's used for household cleaning, laundry boosting, deodorising and DIY projects. Choose the 4kg pack for home use or the 25kg bag for bigger jobs.

Safe Handling Tips

These are concentrated products, so a little goes a long way. Measure carefully, stick to the rates on the label, and water fertilisers in well after spreading to avoid leaf and root burn.

Wear gloves and avoid breathing in fine dust, especially with sulphur and copper powders. Don't apply sulphur in temperatures above about 30°C or within a few weeks of an oil spray. Store all products sealed, dry and out of reach of children and pets.

FAQs

What is Redox?

Redox is an Australian chemical and ingredients distributor founded in Sydney in 1965. It supplies raw materials such as sulphate of ammonia, magnesium sulphate, copper oxychloride, sulphur and borax to agriculture, horticulture and many other industries.

What is sulphate of ammonia used for?

Sulphate of ammonia is a fast-acting nitrogen and sulphur fertiliser. It's used to green up lawns, boost leafy vegetables and acidify alkaline soils for plants like azaleas and blueberries.

Are Epsom salts good for plants?

Yes, when plants are short of magnesium. Epsom salts correct the yellowing between leaf veins caused by magnesium deficiency. If your plants aren't deficient, adding more won't improve growth, so test first.

What does copper oxychloride control?

Copper oxychloride protects against a wide range of fungal and bacterial diseases, including peach leaf curl, early and late blight, downy mildew, rust, black spot and leaf spot. It works as a preventative, so reapply after rain.

Is sulphur dust safe to use in the garden?

Yes, used correctly. Sulphur is a low-toxicity natural mineral. Apply it in cool weather, avoid moisture-stressed plants, wear a dust mask, and don't use it within a few weeks of white oil or other oil sprays.

Do you sell Redox products in bulk?

Yes. Many Redox products are available in sizes from 1kg up to 25kg bags, which suit larger gardens, orchards, farms and regular users.
