Cartap is a chemical compound from the group of thiocarbamates .
Extraction and presentation
Cartap can be obtained by reacting 1,3-dichloropropyldimethylamine with sodium thiocyanate , water , hydrogen chloride and methanol .
properties
Cartap is a colorless solid that is soluble in water.
use
Cartap - and its hydrochloride - is an insecticide developed by Takeda Chemical Industries . It is a derivative of Nereistoxin , a naturally occurring insecticidal substance that was isolated by Nitta in 1934 from the marine arthropods Lumbrinereis heteropoda and Lumbrinereis brevicirra . Its structure was analyzed by Okaichi and Hashimoto in 1962 and by Hagiwara et al in 1965. synthesized. Cartap is converted into neurotoxin in the insect organism, which affects the nervous system.
Admission
In the European Union, Cartap was not included in Annex I of Directive 91/414 / EEC with Regulation (EC) No. 2076/2002 of November 20, 2002. For this reason, no plant protection products containing Cartap may be approved in the member states of the EU. A transition period until mid-2007 was planned for Italy because the active ingredient was difficult to replace in certain applications.
In Germany, Austria and Switzerland, no pesticides with this active ingredient are permitted.
