DESCRIPTION:

BRIEF SUMMARY
The present invention relates to a fungicidal mixture which comprises ##STR3## 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 ##STR4## where the substituents have the following meanings: 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 can 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; CH.sub.2 CH.sub.3 III
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 compounds I and/or II and the compound 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).
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 1 95 28 651.0.
The compound III (German Laid-Open Application DOS 15 67 169, common name: propamocarb), its preparation and its action against harmful fungi have also been disclosed.
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 mixture defined at the outset. Moreover, we have found that better control of the harmful fungi is possible by applying the compounds I and/or II and the compound III simultaneously together or separately or by applying the compounds I and/or II and the compound 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 compounds I.12, I.23, I.32 and I.38 are especially preferred.
In particular, the general formula II represents methoxyacrylates and oxime ethers where X is oxygen and Y is CH, or X is amino and Y is N.
Moreover, preferred compounds II are those where Z is oxygen.
Equally, preferred compounds II are those where R' is alkyl or benzyl.
Particularly preferred with a view to their use in the synergistic mixtu
