Carbosulfan is a chemical compound from the group of sulfenamides , carbamates and substituted oxygen-containing heterocycles .
Extraction and presentation
Carbosulfan can be obtained by reacting carbofuran with sulfur dichloride and dibutylamine .
properties
Carbosulfan is a brown liquid that is practically insoluble in water.
use
Carbosulfan is used as a broad spectrum insecticide similar to the related carbofuran. The effect is based on the inhibition of acetylcholinesterase . Several metabolites are produced upon breakdown, including carbofuran and dibutylamine.
Admission
In Switzerland, carbosulfan was contained in preparations against wireworms and white grubs, as well as against a number of insect pests on some vegetables and ornamentals. These products were taken off the market in May 2012, the use-by period expired in May 2013. In the EU countries including Germany and Austria as well as in Switzerland, no pesticides containing this active ingredient are currently approved.
