Fungicides for Garden Plants, Fruit and Veg
A fungicide is a spray or powder that stops and controls fungal diseases on plants, like black spot, powdery mildew, rust and leaf curl. At Bonnyrigg Produce & Garden Supplies, we stock a full range of fungicide for the garden, from copper and sulphur sprays to systemic options for roses, fruit trees and veggies. Whether you need a garden fungicide to treat an outbreak or a preventative spray before the wet season, it's here. You can buy fungicide online for delivery across Australia, or pick it up in store. Catch disease early and a single spray often saves the plant.
How to choose the right fungicide
Start by naming the disease, then the plant. A systemic fungicide moves inside the plant and works from within, which suits ongoing problems like black spot on roses. A contact fungicide coats the leaf surface and stops spores taking hold, so it works better as a preventative before rain. Timing matters as much as the product, since most fungicides protect better than they cure. If the marks turn out to be insect damage rather than disease, our Insecticides range sorts the bugs.
Copper and sulphur fungicide sprays
The old reliables still do the heavy lifting. A copper fungicide like liquid copper or copper oxychloride is a broad spectrum fungicide for leaf spot, blight, downy mildew and brown rot. Sulphur sprays, including lime sulphur and wettable sulphur, clean up powdery mildew, rust and mites over winter. Both count as an organic fungicide when used as directed, which is why they stay a garden staple. Keep a copper fungicide spray on hand through the wet months for quick action.
Fungicide for fruit trees, roses and vegetables
Different plants cop different diseases. On fruit trees, a copper spray tackles peach leaf curl and brown rot, making it the go-to fruit tree fungicide for late winter. Roses need a black spot fungicide and a powdery mildew treatment through the warmer months. For the veggie patch, a vegetable fungicide handles blight on tomatoes, downy mildew on cucurbits and rust on beans. Grapes and citrus get their own routine, and clearing weeds that harbour spores with our Herbicide range helps keep disease down.
Systemic, contact and preventative options
Match the format to the job. A fungicide concentrate mixes into a sprayer and covers a big garden cheaply, while ready-to-use bottles suit a single rose or pot. A preventative fungicide sprayed before disease shows saves far more plants than a rescue spray afterwards. For orchards and larger blocks, a professional or agricultural fungicide steps up the strength. Rotate products through the season so fungi don't build resistance to one active.
Fungicide brands we stock
We keep the fungicide brands Aussie gardeners already know. Yates covers the everyday copper, sulphur and systemic rose sprays, while David Grays and Barmac handle the straight actives like lime sulphur, wettable sulphur and copper oxychloride. Amgrow rounds out the garden range, and Bayer and Redox bring stronger, professional-grade options for bigger jobs. Between them, every common disease from black spot to leaf curl has a fix.

Fungicide FAQs
What is the best fungicide for black spot on roses?
A systemic rose fungicide is best for black spot because it works from inside the leaf, though a copper or sulphur spray also helps as a preventative. Spray every one to two weeks through the warm, humid months and clear fallen leaves to stop reinfection.
What is the difference between copper and sulphur fungicide?
Copper fungicide is a broad spectrum option for leaf spot, blight and brown rot, while sulphur targets powdery mildew, rust and mites. Many gardeners use copper in the cooler wet season and sulphur through the warmer months.
When should I spray fruit trees for leaf curl?
Spray a copper fungicide for peach leaf curl in late winter, just before the buds swell, then again as they open. Once leaves are curled the spray can't reverse it, so timing before bud burst is the key.
Is there an organic fungicide option?
Yes. Copper and sulphur sprays are accepted for organic gardening when used as directed, and they control a wide range of common diseases. Always follow the label rate and avoid spraying in hot weather.
How often should I use a preventative fungicide?
Through the disease season, spray a preventative fungicide every one to two weeks and after heavy rain, since spores spread in wet conditions. Rotate between a copper and a systemic product so fungi don't build resistance.
Can I buy fungicide online in Australia?
Yes. Order fungicide online for delivery across Australia, or collect free from our Bonnyrigg store, with local delivery available nearby.
