What is Dichlofluanid?

Plain description, key identifiers and synonyms

Dichlofluanid is a member of the class of sulfamides that is sulfamide in which the hydrogens attached to one of the nitrogens are replaced by methyl groups, while those attached to the other nitrogen are replaced by a phenyl and a [dichloro(fluoro)methyl]sulfanediyl group. A fungicide introduced in 1965 and used in the cultivation of fruit and vegetables, as well as in wood preservatives, it is no longer approved for use in the European Union. It has a role as an acaricide and an antifungal agrochemical. It is an organochlorine compound, an organofluorine compound, a member of sulfamides and a phenylsulfamide fungicide. It is functionally related to a sulfamide.
