Liquid composts are reputed to be beneficial to plants however I am not
sure
whether I am a beneficiary of this or some other plausible
explaination.

Was it a home made brew?

Perhaps it was a bit acidic and poisoned the pests, plus if it
contained any sulphur this would help to clear the 'black spot'

maybe, it is a backyard liquid compost with the organic matter perpetually
rotting in the water rather than finished compost soaked in to some water
for a period of time. I have not bothered checking the acidity or mineral
content. It does have quite a bit of sea weed in it but that should be
nutrient balanced and not too salty.
