Fluvalinate is a chemical compound selected from the group of the pyrethroids, which occurs in several isomeric forms. Tau-fluvalinate ( τ - fluvalinate ) is the trivial name of ( 2RS -D) - fluvalinate.

Production and representation

Fluvalinate can be obtained from 4- trifluoromethylaniline and 2- chloro-4- trifluoromethylaniline starting.

Properties

Tau - fluvalinate is an oily yellow liquid. It decomposes rapidly under aerobic conditions but is stable under anaerobic conditions. It is not bioaccumulative, non-volatile and has a low solubility in water. She is very sensitive to light.

Use

Tau-fluvalinate is a broad-spectrum insecticide and acaricide from the class of pyrethroids. It is approved in the U.S. against the Varroa mite in beehives and for several other applications, for example in ornamental plants and in seed multiplication of carrots and cabbages. Tau-fluvalinate was first registered in 1983 for the Zoecon Corporation in the form of a racemate of fluvalinate.

In the European Union tau-fluvalinate is June 1, 2011, a permitted plant protection drug for uses as insecticide and acaricide. In Germany and Austria, a product with the active ingredient tau-fluvalinate against aphids in cereals, some biting insects is admitted to rape and pollen beetles on different types of cabbage. In Switzerland, there is currently no plant protection products containing this active substance on the market. In addition, tau-fluvalinate is also used in Europe to combat the Varroa mite.
