Abstract
Abstract (Thio)-ureas of the formula ##STR1## in which R 1 is an optionally alkyl-substituted cycloalkyl radical or a halogenoalkyl radical, R 2 is an alkyl or cycloalkyl radical or an optionally substituted aryl radical, Ar is an optionally substituted aryl radical, at least one of the radicals R 1 , R 2 and Ar carrying fluorine or a fluorine-containing substituent, and X is an oxygen or sulphur atom, which possess fungicidal activity. Novel intermediates are also disclosed.
