... the adverts for bronze garden tools say that the minute amount of
copper that ends up in the ground acts as a slug dererent, so who knows.

If that were true slug deterrance would be easy by watering in a soluble
copper salt.

You could make it sound exotic by calling it Bordeaux mix.

Its all very true!
I dont know if Bordeaux mix deters frogs, and i haave never used bronze
garden tools myself. What i do know is that there isnt an easy answer to
slugs, and Mikes original experiment idea might hit on something.
There is more in electrical copper than pure copper anyway, the whole idea
of tinned wire creating an electrolytic effect MIGHT be a deterrent for a
problem.

Encouraging frogs seems to work to! for me and some friends anyway, but i
know it doesnt work everywhere.

Where i used to live, only three miles away, slugs wewe endemic. Here they
are not so much of a problem, which says to me that the sciel=nce of
deterency is a delicate one.

So i think Mike should be encouraged to go on with his wire experiment.
