General description

Metaldehyde is an active ingredient, commonly used in organic pesticides, which can be widely used in agriculture in order to control mollusca species like snails, slug etc.
Ethanol is an alcohol. The monitoring of ethanol levels is very important in control of fermentation processes and in certification of alcoholic beverages.

Caution

Pertains only in Germany: Nicht zu Fertigungszwecken1
