Formetanate is a chemical compound from the group of amidines and carbamates.

Production and representation

Formetanate can be obtained by the reaction of m-aminophenol with dimethylformamide, phosphorus oxychloride and methyl isocyanate by the action of hydrochloric acid.

Properties

Formetanate is a colorless to pale yellow solid with a faint odor. It decomposes when heated above 200-202 ° C. In the bottom, under the action of UV light and in solution, the compound decomposes rapidly, with result depending on mining conditions, among others, 3 -aminophenol and Formaminophenol.

Use

Formetanate is used as an insecticide and acaricide against spider mites and some insects (Diptera, Hemiptera and Thysanoptera ) in fruits, vegetables and alfalfa. It is a weak cholinesterase inhibitors. Formetanate was 1969-1991 approved in Germany.

In the headlines the connection came in 2008 as residues were detected in strawberries, but were harmless in their amount according to a statement from the Federal Institute for Risk Assessment.

In the European Union Formetanate may be authorized for uses as insecticide and acaricide since October 2007. In Germany, Austria and Switzerland, no plant protection products containing this active ingredient are allowed. In some southern European countries consist approvals for products with Formatanat.
