Dear All,
On Sunday's Gardeners Question Time on Radio 4, in a discussion
on slug control on runner beans an anti-slug spray was mentioned. It
was described as an organic, calcium based spray that can be applied
to the leaves and deterred the slugs. See
http://www.bbc.co.uk/programmes/b047cb01 25 minutes into the
recording. Does anyone know what this stuff is and where it can be
obtained?

It appears to be slaked lime and is only Organic(TM) in the sense that
the Henry Doublspeak organisation does not absolutely forbid using it.

That is nonsense. It is organic in the sense that it is a normal
part of the extended biosphere (i.e. including compounds that are
recyclable decomposition products of biological organisms), and is
readily usable/decomposable/etc. by normal and common natural chemical
and biochemical pathways. Just like chalk, table salt etc.

Unlike those, it is not a common part of the biosphere, but it is
created (perhaps via quicklime) whenever a volcano erupts under
limestone or chalk and probably under other circumstances.
