Dazomet is an active ingredient for plant protection and a chemical compound from the group of dithiocarbamates.

History

Dazomet was first synthesized in 1890 by Dr. Delepine by the reaction of carbon disulfide with Trimethyltrimethylentriimin and 1968 first registered in Belgium as a pesticide by BASF. It has been studied in Germany in 1971 and its impact by 2012 is patented in Europe.

Production and representation

Dazomet is obtained commercially by the reaction of carbon disulfide with methylamine and formaldehyde.

Properties

Dazomet decomposes at a temperature as 104 ° C. As a technical product, it comes with a purity of 98 % on the market. It is moderately stable, but prone to temperatures greater than 35 ° C and humidity. It hydrolyzes rapidly in water. In the decomposition of methyl isothiocyanate dazomet arises inter alia, the actual active ingredient. A compound having the same basic structure is the antimycotic sulbentine.

Use

Dazomet is used as a fungicide, herbicide, insecticide and nematicide. In Switzerland and Austria dazomethaltige pesticides for use against soil-borne pests are allowed, in Germany there is no admission.
