DESCRIPTION:

BRIEF SUMMARY
The present invention relates to a fungicidal mixture which comprises ##STR4## where T is CH or N, n is 0, 1 or 2 and R is halogen, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -haloalkyl, it being possible for the radicals R to be different when n is 2, and/or ##STR5## where the substituents have the following meaning: X is oxygen or amino (NH); -C.sub.4 -alkyl); -C.sub.6 -alkenyl, C.sub.2 -C.sub.6 -haloalkenyl, C.sub.3 -C.sub.6 -alkynyl, C.sub.3 -C.sub.6 -haloalkynyl, C.sub.3 -C.sub.6 -cycloalkylmethyl, or is benzyl which can be partially or fully halogenated and/or have attached to it one to three of the following radicals: cyano, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -haloalkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkoxy, and C.sub.1 -C.sub.4 -alkylthio; and ##STR6## in a synergistically active amount.
Moreover, the invention relates to methods of controlling harmful fungi with mixtures of the compounds I and/or II and III and to the use of the compound I and/or II and the compounds III for the preparation of such mixtures.
The compounds of the formula I, their preparation and their action against harmful fungi have been disclosed in the literature (WO-A 96/01,256 and WO-A 96/01,258).
The compounds of the formula II, their preparation and their action against harmful fungi have been described in WO-A 95/21,153, WO-A 95/21,154 and DE-A 1 95 28 651.0.
The acaricides III, their preparation and their use against arachnids have also been disclosed (III.a: CAS RN 120928-09-8, common name: fenazaquin; III.b: EP-A 289 879, common name: tebufenpyrad; III.c: CAS RN 111812-58-9, common name: fenpyroxymate; III.d: CAS RN 96489-71-3, common name: pyridaben).
It was an object of the present invention to provide mixtures which have an improved activity gainst harmful fungi combined with a reduced total amount of active ingredients applied (synergistic mixtures) with a view to reducing the rates of application and to improving the spectrum of action of the known compounds.
Accordingly, we have found that this object is achieved by the mixtures defined at the outset. Moreover, we have found that better control of the harmful fungi is possible by applying a compound I and/or II and the compounds III simultaneously together or separately or by applying a compound I and/or II and the compounds III in succession than when the individual compounds are used.
In particular, the formula I represents carbamates in which the combination of the substituents corresponds to one line of the table which follows:

The formula II represents, in particular, oxime ethers where X is oxygen and Y is CH or X is amino and Y is N.
Also preferred are compounds I where Z is oxygen.
Equally preferred are compounds II where R' is alkyl or benzyl.
