Label teardown
What the pack promises versus what the label chemistry actually is.
The marketing claim
“Controls blackspot, rust and mildew on roses and ornamentals”
The chemical reality
Rose Clear Ultra is myclobutanil at about 0.875 g/L in the concentrate bottle — a triazole fungicide sold in a rose-shaped label. Technical myclobutanil powder dissolved to the same ppm is the same systemic without the garden-centre premium.

The Marketing Claim & The Catch
A 1 litre pack of Rose Clear Ultra Concentrate typically retails around £11.99 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 and mildew on roses and ornamentals; Also kills aphids and spider mites on contact; and Concentrate — dilute before spraying.
The catch: Rose Clear Ultra is myclobutanil at about 0.875 g/L in the concentrate bottle — a triazole fungicide sold in a rose-shaped label. Technical myclobutanil powder dissolved to the same ppm is the same systemic without the garden-centre premium.

Proprietary Blend & Dosage Breakdown
The labelled active is Myclobutanil at 0.0875%. Everything else in the pack is solvent and emulsifiers.
At 0.0875% 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% Myclobutanil 96% technical, mixed to 0.91 g per 10 L water (≈0.087 g/L — Rose Clear Ultra strength).

Working strength: 0.91 g per 10 L water (≈0.087 g/L — Rose Clear Ultra strength). Indicative cost £0.03 per diluted litre — 82% 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 label on the powder you buy. Gloves, goggles, no spray drift onto ponds.
- Dissolve 0.91 g of myclobutanil technical in 10 L of water with a few drops of washing-up liquid as wetter.
- Spray dry foliage until run-off. Systemic — allow several days before rain if the label requires.
- 100 g of technical at 0.91 g per 10 L batch makes about 1,100 litres of working spray.
- Triple-rinse sprayers; rotate fungicide groups if blackspot persists.

Active ingredient and cheaper alternative — FAQ
Is Rose Clear the same as Bordeaux mixture?
No. Bordeaux is copper plus lime (contact fungicide). Rose Clear is myclobutanil (CAS 88671-89-0), a systemic triazole. Different chemistry, different crop labels.
Can I use SBK triclopyr on roses?
Wrong tool. SBK is triclopyr for woody weeds. Rose blackspot needs a fungicide such as myclobutanil — see this teardown, not the SBK one.
How do you mix the Rose Clear Ultra Concentrate dupe stack?
Pesticide: read the label on the powder you buy. Gloves, goggles, no spray drift onto ponds. Dissolve 0.91 g of myclobutanil technical in 10 L of water with a few drops of washing-up liquid as wetter. Spray dry foliage until run-off. Systemic — allow several days before rain if the label requires. 100 g of technical at 0.91 g per 10 L batch makes about 1,100 litres of working spray. Triple-rinse sprayers; rotate fungicide groups if blackspot persists.
