Label teardown

The marketing claim
“Controls blackspot, rust, powdery mildew and box blight”
The chemical reality
Provanto Fungus Fighter is tebuconazole at 25 g/L in a 125 ml rose bottle. Four millilitres per litre lands at about 0.1 g/L — the same DMI triazole as a weighed pinch of 96% technical. It is not myclobutanil (Rose Clear), not sulphur, and not Bordeaux copper.

The Marketing Claim & The Catch
A 125 millilitres pack of Provanto Fungus Fighter Concentrate typically retails around £9.99 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: Controls blackspot, rust, powdery mildew and box blight; Contact and systemic — up to four weeks’ protection; and 125 ml makes around 31 litres of spray.

Proprietary Blend & Dosage Breakdown
The labelled active is Tebuconazole at 2.5%. Everything else in the pack is suspo-emulsion (water and solvents).
At 2.5% 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% Tebuconazole 96% technical, mixed to 1.04 g per 10 L water (≈0.1 g/L — Provanto 4 ml/L band).

The Active Chemical Alternative (Dupe Stack)
The dupe stack is Tebuconazole 96% technical at 96% bulk. Indexed as CAS 107534-96-3, formula C16H22ClN3O. Buy it as 100 grams for around £28.00 from Amazon UK.
Working strength: 1.04 g per 10 L water (≈0.1 g/L — Provanto 4 ml/L band). Indicative cost £0.03 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 (Repr. 2 on many tebuconazole labels — read the SDS). Gloves, goggles, no spray if you are pregnant. Keep off ponds.
- Dissolve 1.04 g of tebuconazole 96% technical in 10 L of water with a drop of washing-up liquid as wetter — about 0.1 g/L, matching 4 ml of the 25 g/L Provanto bottle in a litre.
- Spray dry foliage until glistening. Allow the labelled interval before rain. Typical coverage is about 2 m² per working litre on roses and box.
- 100 g of technical at 1.04 g per 10 L batch makes about 960 litres of working spray — many 125 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 Fungus Fighter the same as Rose Clear Ultra?
Same job family (systemic triazole fungicides) but different molecules. Rose Clear is myclobutanil (CAS 88671-89-0). Provanto is tebuconazole (CAS 107534-96-3). Rotate groups if blackspot persists; do not stack them in one tank.
Will yellow sulphur replace this spray?
No. Elemental sulphur is a contact dust or wettable wash. Tebuconazole is systemic. Different crop labels, different PPE, different resistance management.
How do you mix the Fungus Fighter Concentrate dupe stack?
Pesticide (Repr. 2 on many tebuconazole labels — read the SDS). Gloves, goggles, no spray if you are pregnant. Keep off ponds. Dissolve 1.04 g of tebuconazole 96% technical in 10 L of water with a drop of washing-up liquid as wetter — about 0.1 g/L, matching 4 ml of the 25 g/L Provanto bottle in a litre. Spray dry foliage until glistening. Allow the labelled interval before rain. Typical coverage is about 2 m² per working litre on roses and box. 100 g of technical at 1.04 g per 10 L batch makes about 960 litres of working spray — many 125 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.
