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 -cycloalkyl-methyl, or benzyl which may be partially or fully halogenated and/or may carry 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; ##STR6## where L.sup.- is a hydroxyl or acetate group, 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 compounds I and II and 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-A 19 528 651.0.
The compounds III (L.sup.- =OH.sup.- : CAS RN: [76-87-9]; common name: fentin hydroxide; L.sup.- =CH.sub.3 CO.sub.2.sup.- : U.S. Pat. No. 3,499,086; common name: fentin acetate), their preparation and their 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 compound I and/or II and the compounds III in succession than when the individual compounds are used.
The invention covers binary mixtures of compounds I or II and III and also ternary mixtures of I, II and III.
In particular, the formula I represents carbamates in which the combination of the substituents corresponds to one line of the table which follows:
