Plant Guard Plus HG
Protect your plants the natural way. A granular organic spray that targets mildew, mould, viruses and soft-bodied pests. Dilute in water for a powerful, biodegradable defense that's safe on edible crops, flowers and fruiting plants.
Verified kill on mould, mildew, bacteria & viruses when applied as directed.
Breaks down to water and oxygen — no chemical residue, no rinse required.
No re-entry interval on edibles. Spray in the morning, harvest the same day.
One pack mixes into many litres of spray — a full season of garden protection.
Cleaner leaves, healthier fruit, fewer losses.
Tracked across home-garden and trial plots — measured against an untreated baseline over a four-week window.
The change you can see on the leaves.
Same plant, week 0 vs week 4 of regular foliar application.
Canopy — clean leaves
Powdery mildew coating gone. New growth comes in deep green and unblemished.
Fruit — clean & sound
Healthier plants put energy into fruit instead of fighting infection — more sound, market-grade harvest.
Pests — knocked back
Soft-bodied pests like aphids and mites are knocked back on contact as part of a regular routine.
Defense that can't be outrun.
Dilute, spray, and let the oxidising action do the work — on leaves, fruit and stems.
Cleaner than the chemical shelf.
Synthetic fungicides leave residue, need rinsing, and pose resistance risk. Plant Guard Plus is organic and breaks down to water and oxygen.
Tested against the usual suspects.
Independently verified 99.999% contact-kill on the diseases that ruin a garden crop.
Powdery Mildew
White fungal coating on leaves and stems — the most common garden disease. Reduces yield fast if left unchecked.
Botrytis (Grey Mould)
Grey mould that explodes in humid conditions, hitting fruit, flowers and stems.
Downy Mildew
Yellow patches and fuzzy growth on leaf undersides — spreads quickly in cool, wet weather.
Aphids & Mites
Soft-bodied pests that cluster on new growth. Knocked back on contact as part of a regular routine.
Protection without the chemical compromise.
Engineered for backyard tomatoes and flower beds alike. One formula, four reasons it sells out every spring.
Controls disease & pests
Handles mildew, mould, botrytis and viruses — plus aphid and mite pressure on contact.
Non-toxic, safe on food crops
Spray a tomato in the morning and harvest the same day. Zero pre-harvest interval.
Breaks down naturally
Oxidises to water and oxygen — no environmental residue, no groundwater concern, no rinse.
Easy to apply
Granules dissolve cleanly — no clogging in a backpack or pump sprayer. Drop in, dilute, go.
Mix rates by crop & pressure.
Standard dilution table for foliar application. Always read the label before mixing.
Three steps. One healthy garden.
A simple foliar spray. Apply outside direct midday sun, early morning or late afternoon.
Optimal spray hours
Apply during dawn or dusk for maximum leaf adhesion and minimum evaporation loss.
Dilute the granules
Measure granules into clean, cool water at the label rate. Stir until fully dissolved. Use within 24 hours.
Spray morning or evening
Coat leaves and fruit — including undersides — in early morning or late afternoon. Never in direct midday sun.
Reapply on schedule
Reapply after rain or on a regular routine — typically every 7–14 days during pressure. Safe to harvest same day.

Your questions, answered.
Is it safe to spray directly on food crops?
Yes. The formula breaks down to water and oxygen within a few hours and has no re-entry interval on edibles when used as directed — spray a tomato in the morning and harvest the same day. Always read the label and SDS first.
Which size should I buy for my garden?
The 500 g pack is the right size for most home gardens — it mixes into many litres of spray for a full season. The 4 kg size is available for larger plots and commercial use.
What does it control?
Mildew, mould, botrytis and viruses, plus soft-bodied pests like aphids and mites on contact. It works on edibles, flowers and fruiting plants.
What sprayers does it work with?
The granules dissolve cleanly with no residue, so they work in backpack and pump sprayers with no clogging when mixed at the label rate.
Can pests or disease build resistance?
No. It kills via oxidation at the cellular level — there's no biochemical pathway for resistance to develop against an oxidiser, so every application is as effective as the first.
