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

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?!

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.

Nick Maclaren.

Is it perhaps food grade Diatomaceous Earth mixed with water and sprayed
onto the plants.

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.

Slaked lime isn't likely to encourage snails is it?! They are attracted to
limestone rocks and lime washed walls etc. for calcium for their shells
aren't they?

re; 'organic' from a chemistry class standpoint it is a small irony
that Calcium Hydroxide is a carbon-free ionic bonded compound!

This topic is also being discussed here
http://www.growfruitandveg.co.uk/gra...ray_80383.html
where the poster writes,

"I think the speaker probably meant this stuff Grazers Slugs and Snails
(http://www.gardening-naturally.com/a...nd-Snails.html)
which, if is like Sluggo is based on Iron Phosphate and
interferes with the slug/snail's calcium metabolism. So not based
on calcium."

Anyone like to comment?

Regards
Tom.
