Disclosed are fungicidal mixtures containing a synergistically effective amount of A) a triazolopyrimidine of formula I, and B) imidazole derivatives of formula II, wherein X1 and X2 represent halogen and phenyl which can be substituted by halogen or alkyl, or X1 and X2 form a difluoromethylendioxyphenyl group along with the bridging C═C double bond, X3 represents cyano or halogen, and X4 represents dialkylamino or isoxazol-4yl that can carry two alkyl radicals. The invention also relates to methods for controlling destructive fungi by means of mixtures of compounds I and II, agents containing said mixtures, and the use of compounds I and II for producing such mixtures.
