CAS 108 62 3 6% GR Metaldehyde Insecticide

It is sold under various trade names as a molluscicide, including Antimilice,
Ariotox, Blitzem (in Australia),

Cekumeta, Deadline, Defender (in Australia), Halizan, Limatox, Limeol, Meta,
Metason, Mifaslug, Namekil, Slug Fest Colloidel 25, and Slugit.

Typically it is applied in the form of slug pellets, which normally include a
wheat bait.

Metaldehyde acts on the pest by contact or ingestion, and the aqueous
environment inside the pest's cells readily hydrolyzes

metaldehyde into acetaldehyde, the molecule associated with an alcohol
hangover.

Due to the contamination of drinking water by metaldehyde's use in agriculture
a specialist organisation was established in 2008

called "The Metaldehyde Stewardship Group (MSG)".

On 19 December 2018, the British government banned the use of metaldehyde slug
pellets outdoors from spring 2020;

after this date it would only be legal to use it in permanent greenhouses.

In July 2019, the ban was overturned after the High Court in London agreed with
a challenge to its legality.

Metaldehyde pellets returned to the UK market for the foreseeable future
