Bromopropylate is a chemical compound selected from the group of carboxylic acid esters.

Production and representation

Bromopropylate can be obtained by esterification of Dibrombenzilsäure with isopropanol.

Properties

Bromopropylate is a flammable white solid that is practically insoluble in water. It is relatively stable in neutral or slightly acidic media.

Use

Bromopropylate is used as an acaricide for the control of spider mites in bee-keeping as well as in citrus, fruit and grapes. The use against mites was tested for the first time in 1966. The connection was approved 1982-1994 in the GDR. Under the name Folbex VA it was used in Räucherstreifen against the Varroa mite.

In the European Union Bromopropylate has not been included in Annex I to Directive 91/414/EEC by Commission Regulation ( EC) No 2076 /2002 of 20 November 2002. Therefore, in the States of the EU, no pesticides may be allowed to contain Bromopropylate. For Belgium and Spain, a transition period was provided by mid-2007 because the drug was difficult to replace in certain cultures.

In Switzerland, pesticides are approved with this drug, in Germany and Austria no.
