Friend wants to rid his lawn of a number of fairy rings, I suggested in the
old days he could have used Armilatox, what is now sold as just a patio
cleaner, but what strength did one use it at in those days to rid a lawn of
fungi? I'm not suggesting for one moment he breaks the law and uses it for
that purpose now. :-)

A friend put down a plastic sheet all around the ring she had in her
lawn (her parents lawn actually - she would never get rid of hers),
forming a circle from the ring to about 1m wide outwards. The spores of
the fungi 'fly' outwards (hence the rings usually getting bigger year
after year) and were collected in the sheet. She did this over two
seasons and the fungis desappeared without using any chemicals. Sorry
Bob, but you know me .... )
