That is probably a lower concentration version of BAC50.

BAC 50 prices seem to have risen significantly during our lockdowns but
should fall back to around £25 for 5L (incl postage), as they did after
the first lockdown.

I prefer to use biological washing powder, cheaper and just as
effective, also kinder on other things in and around the garden.

....is the right answer. I use four times the normal (washing)
concentration and apply it via a watering can. It's cheap, cheerful, and
effective. The moss I bumped off last October has just started to make a
much-weakened re-appearance, which was very easy to re-treat. I doubt
I'll see it again until November.

For small areas or difficult-to-reach areas I use the same dilution in a
used trigger-pack.
