Ferbam is a chemical compound from the group of dithiocarbamates , which - like other dithiocarbamates - is used as a pesticide.

Extraction and presentation

Ferbam can be obtained by reacting carbon disulfide with dimethylamine and sodium hydroxide and further reaction of the intermediate product ( sodium dimethyldithiocarbamate ) with iron (III) sulfate .

use

Ferbam was used as a broad spectrum fungicide on fruit, various fruits and berries, as well as potatoes and tobacco. The first investigations into the toxicological properties of the compound took place in the mid-1960s.

Admission

In 1995 Ferbam's approval as a plant protection product was revoked in the EU. In EU countries such as Germany, Austria and Switzerland, no pesticides containing this active ingredient are approved.

The permitted daily dose of Ferbam is set at 3 µg / kg / d.
