Aptus Fungone 1L - Ready-to-Use Foliar Spray Against Fungal and Bacterial Problems
Best for: growers wanting a preventative foliar spray against mould, mildew and bacterial leaf problems, particularly outdoors.
Our thoughts
This is a prevention tool, not a rescue remedy for a plant that is already covered in mould. Used weekly through the cycle it keeps leaf surfaces cleaner and less hospitable to fungal and bacterial problems before they take hold, which is a much easier position to be in than trying to treat an active infection. Just remember to spray with the lights off, this one is very clear about that.
Fungone is a ready-to-use foliar spray built around food grade hydrogen peroxide (3%) combined with colloidal silver and a food grade adjuvant that helps the spray stick and spread evenly across the leaf surface. It works by oxidation, using active oxygen released from the hydrogen peroxide to oxidise bacteria and fungi on contact, a mechanism pathogens cannot easily develop resistance to. What is left behind breaks down into natural oxygen and water, leaving no toxic residue on the plant.
It is designed as a preventative shield sprayed directly onto leaves, aimed particularly at growers dealing with outdoor conditions where fungal and bacterial pressure tends to be higher. A concentrate version is also available, where 1 litre makes up to 5 litres of ready-to-use spray.
How it compares
Foliar sprays for fungal and bacterial prevention range from simple hydrogen peroxide dilutions to branded proprietary blends.
- Compared with plain diluted hydrogen peroxide from a pharmacy, Fungone adds colloidal silver and a food grade adjuvant that helps it spread and stick to leaf surfaces rather than just running off.
- Against systemic fungicides, Fungone works purely on contact and by oxidation rather than being absorbed and acting from within the plant, which suits growers who want a non-systemic, non-toxic option.
- Compared with SB Plant Invigorator, which targets pests as well as some fungal issues, Fungone is specifically focused on fungal, bacterial and viral leaf problems rather than pest control.
It is a straightforward, non-toxic preventative spray rather than a cure for an active outbreak, and is priced and positioned accordingly.
Usage guidance
Fungone is ready to use straight from the bottle, with a few important handling notes.
Application
Spray directly onto plant leaves, covering the surface evenly. If using the concentrate version, dilute 1 part Fungone concentrate to 4 parts water before spraying.
Timing
Always spray with the lights off. Spray droplets can act like small prisms under grow lights, amplifying light intensity and burning the leaf.
Frequency
Use weekly as a preventative measure, up to the last week before harvest.
Safety
Wear a mask and goggles when spraying as standard precaution, even though the product itself is non-toxic to plants and animals.

Our take
Fungone earns its place as a routine preventative spray rather than an emergency fix, and used weekly it is a sensible bit of insurance against fungal and bacterial problems on leaves. Just respect the lights-off rule and you will get the most out of it.
A dependable addition to a weekly IPM routine. Does exactly what it should, day in, day out.
