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.

But wouldn't that do harm to many plants? Are we looking at the cure
being worse than the disease?!

I guess that the main problem would be with ericaceous plants, as slaked
lime is very alkaline. But then you probably wouldn't have need to use
it on ericaceous plants - AFAIAA slugs tend to leave those alone.
