6-(2-Chloro-6-fluoro-phenyl)-triazolopyrimidines of formula (I), in which R<1 >and R<2 >independently denote hydrogen or alkyl, alkenyl, alkynyl, alkadienyl, or haloalkyl, cycloalkyl, bicycloalkyl, phenyl, naphthyl, or 5- or 6-membered heterocyclyl, containing one to four nitrogen atoms or one to three nitrogen atoms and one sulfur or oxygen atom, or 5- or 6-membered heteroaryl, containing one to four nitrogen atoms or one to three nitrogen atoms and one sulfur or oxygen atom, or where R<1 >and R<2 >radicals may be unsubstituted or partially or fully halogenated or may be substituted as defined in the description. R<1 >and R<2 >together with the interjacent nitrogen atom represent a 5- or 6-membered heterocyclic ring, containing one to four nitrogen atoms or one to three nitrogen atoms and one sulfur or oxygen atom, which may be substituted; X is cyano, alkoxy, haloalkoxy or alkenyloxy; processes for their preparation, compositions containing them and to their use for combating phytopathogenic fungi.
