DESCRIPTION:

BRIEF SUMMARY
The present invention relates to a fungicidal mixture which comprises at least one compound selected from the group consisting of ##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; ##STR5## 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 if n is 2, and and IV ##STR6## in a synergistically active amount.
Moreover, the invention relates to methods of controlling harmful fungi with mixtures of the compounds I or II and III or of the compounds I or II and IV and to the use of the compounds I, the compounds II and the compounds III and IV 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 95/21,153, WO-A 95/21,154, DE-A 195 28 651.0).
The compounds of the formula II, 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 phthalimide derivatives III and IV (U.S. Pat. Nos. 2,553,770; 2,553,771; 2,553,776), their preparation and their action against harmful fungi are also 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 or II and the compound III or the compound IV simultaneously together or separately or by applying the compounds I or II and the compound III or the compound IV in succession than when the individual compounds are used.
In particular, the general formula I represents oxime ethers in which X is oxygen and Y is CH or X is amino and Y is N.
Moreover, preferred compounds I are those where Z is oxygen.
Equally, preferred compounds I are those where R' is alkyl or benzyl.
Especially preferred with a view to their use in the synergistic mixtures according to the invention are the compounds I compiled in the tables which follow:
Compounds of the formula IA where ZR' for each compound corresponds to one line of Table A ##STR7## Table 2.
Compounds of the formula IB where ZR' for each compound corresponds to one line of Table A ##STR8##

In relation to the C.dbd.Y double bond, the compounds of the formula I can be in the E or the Z configuration (in relation to the carboxylic acid function). Accordingly, they can be used in the mixture according to the invention in each case either in the
