Toxicological data
As far as possible and customary, SI units are used. Unless otherwise noted, the data given apply to standard conditions .

Cyflufenamid is a chemical compound from the group of amidoximes .

Extraction and presentation

Cyflufenamid can be obtained by a multi-stage reaction starting from 3,4-dichlorobenzotrifluoride via 2,3-difluoro-6-trifluoromethylbenzonitrile .

properties

Cyflufenamid is a white solid with a slightly aromatic odor. It is stable against hydrolysis (5 days at 50 ° C, pH 4, 5 and 7).

use

Cyflufenamid is used as a fungicide in the cultivation of barley, oats, rye, triticale and wheat, especially against powdery mildew .

Admission

Cyflufenamid was developed by Nippon Sōda and was first approved in Japan in 2002. In Germany it was approved in 2006.

Cyflufenamid was approved for use as a fungicide in the European Union with effect from April 1, 2010.

In Germany, Austria and Switzerland, plant protection products (e.g. Vegas) with this active ingredient are approved.
