Label teardown
What the pack promises versus what the label chemistry actually is.
The marketing claim
“3-in-1 systemic — blackspot, powdery mildew and rust”
The chemical reality
Fungus Clear Ultra is triticonazole at 10.2 g/L in a 225 ml rose bottle. Fifteen millilitres per litre lands at about 0.15 g/L — the same DMI triazole as a weighed pinch of 96% technical. It is not myclobutanil (Rose Clear), not tebuconazole (Provanto Fungus Fighter), and not sulphur.

The Marketing Claim & The Catch
A 225 millilitres pack of Fungus Clear Ultra Concentrate typically retails around £10.99 in lawn & garden. That is a UK shelf-price snapshot for the maths on this page — not a live shop quote or a manufacturer RRP. Listings, sizes and deals move. The marketing line is that you are buying a finished lifestyle product, not a weighed chemical.
On the pack: 3-in-1 systemic — blackspot, powdery mildew and rust; Protects new growth for weeks; and Use on roses, ornamentals, trees and shrubs.
The catch: Fungus Clear Ultra is triticonazole at 10.2 g/L in a 225 ml rose bottle. Fifteen millilitres per litre lands at about 0.15 g/L — the same DMI triazole as a weighed pinch of 96% technical. It is not myclobutanil (Rose Clear), not tebuconazole (Provanto Fungus Fighter), and not sulphur.

Proprietary Blend & Dosage Breakdown
The labelled active is Triticonazole at 1.02%. Everything else in the pack is emulsifiable concentrate (solvents and oils).
At 1.02% active, most of what you pay for is carrier and packaging. The brand is selling convenience, fragrance and a label — not a uniquely potent molecule.
Branded working strength is whatever comes out of the bottle. The bulk alternative is 96% Triticonazole 96% technical, mixed to 1.59 g per 10 L water (≈0.15 g/L — Fungus Clear 15 ml/L band).

The Active Chemical Alternative (Dupe Stack)
The dupe stack is Triticonazole 96% technical at 96% bulk. Indexed as CAS 131983-72-7, formula C17H20ClN3O. Buy it as 100 grams for around £28.00 from Amazon UK.
Working strength: 1.59 g per 10 L water (≈0.15 g/L — Fungus Clear 15 ml/L band). Indicative cost £0.04 per diluted litre — 85% below a typical branded pack on a per-litre basis, before you reuse leftover bulk.
Follow the mixing method and the supplier SDS. Wear the listed PPE. Do not mix incompatible oxidisers, acids or ammonia.
- Pesticide: read the MAPP label and SDS on the powder you buy. Gloves, goggles. Keep off ponds, water butts and food crops the label does not name.
- Dissolve 1.59 g of triticonazole 96% technical in 10 L of water with a drop of washing-up liquid as wetter — about 0.15 g/L, matching 15 ml of the 10.2 g/L Fungus Clear bottle in a litre.
- Spray dry foliage until both leaf faces glisten. Repeat at the labelled interval. Typical coverage is about 2 m² per working litre on roses and ornamentals.
- 100 g of technical at 1.59 g per 10 L batch makes about 630 litres of working spray — many 225 ml garden-centre bottles.
- Buy listings a householder can legally apply. Triple-rinse the sprayer; rotate with sulphur or copper if the label allows, rather than repeating one triazole all season.

Active ingredient and cheaper alternative — FAQ
Is this the same as Provanto Fungus Fighter?
Same job family (systemic triazole fungicides) but different molecules. Provanto is tebuconazole (CAS 107534-96-3). Fungus Clear Ultra is triticonazole (CAS 131983-72-7). Rotate groups if blackspot persists; do not stack them in one tank.
Is this the same as Rose Clear Ultra?
No. Rose Clear is myclobutanil (CAS 88671-89-0), often with an insecticide in the ‘Ultra’ gun. Fungus Clear Ultra is triticonazole only. Different HSE numbers, different mixing maths.
How do you mix the Ultra Concentrate dupe stack?
Pesticide: read the MAPP label and SDS on the powder you buy. Gloves, goggles. Keep off ponds, water butts and food crops the label does not name.
