The ROI case

The cost of not using Plant Guard.

A typical 1-acre greenhouse spends $8,000–12,000 per cycle on manual teardown, chemical fungicides and labour.

ROI Snapshot

Up to $8,400 saved per 1-acre cycle.

Two 4 kg units cover a full 1-acre reset — replacing manual teardown crews, chlorine rinse cycles and conventional fungicide applications.

POWDERY MILDEW

Powdery Mildew

White fungal coating on leaves & stems. Reduces yield up to 40% in untreated greenhouses.

BOTRYTIS

Botrytis

Grey mould that explodes in humid greenhouses. Hits fruit, flowers and stems at harvest window.

Class · Fungal99.999% kill
PYTHIUM

Pythium

Root-rot pathogen that spreads through irrigation lines and recirculating water systems.

Class · Oomycete99.999% kill
FUSARIUM

Fusarium

Soil-borne wilt that survives between cycles. Eradicated at reset to prevent carryover.

Facility reset

Break the disease cycle in four hours.

Reset your crop cycle with zero carryover. Fog the facility between cycles or apply foliar during production.

One-pass facility coverage HVAC, benches, floors, walls, drip lines. No missed spots and no manual scrubbing between cycles.
Zero odour · zero residue No noxious smell during or after. Minimal PPE downtime. Safe for organic and export markets — no rinse required.
No resistance pathway Peracetic acid kills via oxidation at the cellular level. Unlike systemic fungicides, microbes can't adapt against an oxidiser.
Plant immunity built in Mono-silicic acid triggers the plant's own immune response — stronger cell walls, better resilience on resumption.

Application protocol

Three steps. One healthier crop.

Foliar spray or facility fog. Apply outside direct midday sun and during favourable canopy humidity.

Daily window

Optimal spray hours

Apply during dawn or dusk for maximum leaf adhesion and minimum evaporation loss.

Dilute as directed

Measure granules into clean cool water at the label rate. Stir until fully dissolved. Use within 24 hours.

RATE10 g / LpH6.5–7.5TEMP< 20°C

Apply foliar or fog

Spray leaves and fruit, or fog the facility between cycles. Coat undersides. Never in direct midday sun.

Why growers choose it

Protection without the chemical compromise.

Engineered for 1-acre commercial fields and greenhouses. One formula, four reasons it sells out every spring.

Controls pathogens & pests

Mildew, mould, botrytis, pythium, fusarium — plus aphid and mite pressure on contact.

Safe on food crops

Zero pre-harvest interval. Spray in the morning, harvest the same day. Safe for organic and export markets.

Breaks down naturally

Oxidises to water and oxygen within hours. No residue, no groundwater concern, no rinse.

Sprayer-compatible

Granules dissolve cleanly — no clogging on backpack, boom or fogging equipment. Drop in, dilute, go.

Grower questions

Grower questions answered.

Q.01

Is it safe to spray directly on food crops?

Yes. It breaks down to water and oxygen within ~4 hours and has no re-entry interval on edibles applied as directed — spray in the morning, harvest the same day. Read the label and SDS before use.

Q.02

How much area does one unit cover?

A single 4 kg unit covers ~22,000 sq ft of greenhouse surface as a facility fog. Most 1-acre operations use two units for a full reset.

Q.03

What equipment is it compatible with?

Granules dissolve cleanly with no residue — backpack, boom, drip lines and ULV foggers, with no clogging at the label rate.

Q.04

Can pathogens build resistance over time?

No. Peracetic acid kills via oxidation at the cellular level — there's no biochemical pathway for resistance against an oxidiser.

Q.05

How is it different from chlorine or quats?

Chlorine and quats leave residue, require rinsing, and aren't compatible with organic or export markets. Plant Guard oxidises to water and oxygen — no rinse, no residue, no compliance risk.

Q.06

How do you ship larger orders?

Ships across Canada, dispatched within 1 business day. Most orders ship free over $199.Shipping policy; heavier orders over 8 kg may carry a freight charge — contact support@morganics.com for bulk and pallet quotes.

Spring Reset

End crop carryover in four hours.

Reset between cycles with zero carryover. Most orders ship free over $199.Shipping policy, backed by our 100-day crop-result guarantee. Bulk and distributor pricing available.
