What is Fluxapyroxad?

Plain description, key identifiers and synonyms

Fluxapyroxad is an aromatic amide obtained by formal condensation of the carboxy group of 3-(difluoromethyl)-1-methylpyrazole-4-carboxylic acid with the amino group of 3',4',5'-trifluorobiphenyl-2-amine. Used to control a number of cereal fungal pathogens including those belonging to the Ascomycetes, Basidiomycetes and Zygomycetes families. It has a role as an EC 1.3.5.1 [succinate dehydrogenase (quinone)] inhibitor and an antifungal agrochemical. It is a member of biphenyls, a member of pyrazoles, an aromatic amide, a trifluorobenzene and an anilide fungicide.
