DESCRIPTION:

BRIEF SUMMARY
The present invention relates to a fungicidal mixture which comprises ##STR3## where X is CH and N, n is 0, 1 or 2 and R is halogen, C.sub.1 -C.sub.4 -alkyl and C.sub.1 -C.sub.4 -haloalkyl, it being possible for the radicals R to be different when n is 2, or a salt or adduct thereof, and ##STR4## where R.sup.1 is fluorine or chlorine, or a salt or adduct thereof, in a synergistically active amount.
Moreover, the invention relates to methods of controlling harmful fungi using mixtures of the compounds I and II and the use of the compound I and the compound II for the preparation of such mixtures.
The compounds of the formula I, their preparation and their action against harmful fungi are disclosed in the literature (PCT WO 96/01,256 and WO 96/01,258).
Also disclosed are the compounds II (EP-A 545 099, EP-A 589 301).
Moreover, DE Appl. No. 19 535 366.8 describes in general form synergistic mixtures which have fungicidal properties and which, on the one hand, comprise a respiration-inhibitory compound and, on the other hand, an anilide derivative of a general formula, which also embraces the compounds II according to the invention. The carbamates of the formula I according to the invention also have a respiration-inhibitory action; however, mixtures with carbamates are not described in DE Appl. No. 19 535 366.8
It was an object of the present invention to provide mixtures which have an improved activity against harmful fungi combined with a reduced total amount of active ingredient applied (synergistic mixtures) with a view to reducing the rate of application and improving the spectrum of action of the known compounds I and II.
Accordingly, we have found that this object is achieved by the mixture defined at the outset. Moreover, we have found that applying the compound I and the compound II simultaneously, ie. together or separately, or applying the compound I and the compound II in succession provides better control of the harmful fungi than is possible with the individual compounds alone.
Formula I represents, in particular, carbamates, in which the combination of the substituents corresponds to one line of the following table:

Especially preferred are the compounds I.12, I.23, I.32 and I.38.
Due to the basic character of the nitrogen atoms which they contain, the compounds I are capable of forming salts or adducts with inorganic or organic acids or with metal ions.
When providing the mixtures, it is preferred to employ the pure active ingredients I and II with which further active ingredients against harmful fungi or against other pests such as insects, arachnids or nematodes, or else herbicidally active ingredients, growth regulators or fertilizers, may be admixed.
The mixtures of the compounds I and II, or the simultaneous,
