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?

Thanks
Tom Crane
