Fungal diseases are one of the most common issues gardeners face in Australia, especially in warm, humid places like the Gold Coast. You might see things like:
White powder on leaves (powdery mildew)
Black spots on rose leaves
Mould on fruit and veggies
Brown patches in your lawn
Fungus spreads fast and can quickly ruin your plants if it’s not treated early. The good news is that, with the right product, you can stop fungus in its tracks and even prevent it from appearing in the first place.
What Is Surefire Stellar Fungicide?
Surefire Stellar Fungicide is a liquid product you mix with water and spray onto your plants. It works to treat and prevent fungal diseases on things like:
Veggies
Fruit trees
Roses
Ornamentals (decorative plants)
Lawns and turf
It contains two active ingredients (Pyraclostrobin and Boscalid), which means it fights fungus in more than one way, making it harder for the disease to come back.
How It Works
Surefire Stellar is what’s called a systemic fungicide. That means once you spray it on your plants, it soaks into the leaves and stems. It doesn’t just sit on the surface, it gets inside the plant and protects it from the inside out.
Here’s what it does:
Stops fungus spores from growing
Prevents new infections
Protects your plants for up to two weeks
Because it attacks the fungus in more than one way, it gives strong, long-lasting protection.
What It Treats
Surefire Stellar is handy for all sorts of fungal issues. Here’s a quick guide to what it treats:
Disease | Plants Affected | What It Looks Like |
---|---|---|
Powdery Mildew | Cucumbers, roses, zucchinis | White powder on leaves |
Black Spot | Roses | Round black spots on leaves |
Botrytis (Grey Mould) | Strawberries, grapes | Grey fuzzy mould on fruit/leaves |
Downy Mildew | Lettuce, basil | Yellow/brown patches on leaves |
Leaf Spot | Ornamentals, vegetables | Spots or holes in leaves |
Sclerotinia | Beans, lettuce | Soft, rotten stems and wilting |
How to Use It Properly
Using Surefire Stellar the right way helps it work better and keeps your plants healthy.
Mixing
Add 30–50 mL of the fungicide to 10 litres of water
Mix in a clean garden sprayer
Shake well before spraying
When to Spray
Best to spray early in the morning or late in the day (not during the heat)
Spray before you see too much damage – it works best as a preventative
Don’t spray right before it rains
How Often
Spray every 10 to 14 days depending on the weather
If growing veggies or fruit, check the withholding period before harvesting (usually 7–14 days)
Tips to Stop Fungal Problems Before They Start
Even with a good fungicide, it helps to keep your garden clean and healthy to stop disease in the first place. Try these simple tips:
Space your plants out so air can move through
Don’t water leaves – water the soil instead
Prune dead or crowded branches
Clean your tools after use
Rotate your crops in veggie gardens
Is It Safe for People, Pets, and the Environment?
Surefire Stellar is safe when used correctly. It’s made to be low-risk to bees and beneficial insects, which is great for eco-friendly gardeners.
Safety Tips:
Wear gloves and eye protection when mixing and spraying
Keep pets and kids away from sprayed areas until dry
Don’t spray near ponds or drains
Always read the label and follow directions
