BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a fungicidal mixture comprising ##STR6## an N-oxide or a salt thereof, where the radicals are defined as follows: R.sup.1, R.sup.2, R.sup.3 and R.sup.4 independently of one another are: hydrogen, hydroxyl, nitro, halogen, 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, C.sub.1 -C.sub.4 -alkylthio, C.sub.1 -C.sub.4 -haloalkylthio; hydroxyl, cyano, nitro, halogen, C.sub.1 -C.sub.7 -alkyl, C.sub.1 -C.sub.7 -haloalkyl, C.sub.1 -C.sub.7 -alkoxy, C.sub.1 -C.sub.7 -haloalkoxy, C.sub.1 -C.sub.7 -alkylthio, C.sub.1 -C.sub.7 -haloalkylthio, C.sub.1 -C.sub.7 -hydroxyalkyl, C.sub.2 -C.sub.4 -acyl, aryl or aryloxy, it being possible for the radicals with aryl to have attached to them, in turn, one to three of the following groups: cyano, nitro, halogen, 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, C.sub.1 -C.sub.4 -alkylthio and C.sub.1 -C.sub.4 -haloalkylthio, or ##STR7## where the radicals are defined as follows: R.sup.8 is cyano, halogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.2 -haloalkyl and C.sub.1 -C.sub.4 -alkoxy, or and/or a phenoxy group, it being possible for the phenoxy group to have attached to it, in turn, one to three of the following substituents: cyano, halogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.2 -haloalkyl and C.sub.1 -C.sub.4 -alkoxy; -C.sub.3 -alkoxy, or
2. Description of the Background ##STR8## or a salt thereof where the radical R.sup.9 is methyl, propyn-1-yl or cyclopropyl, or (2RS,3SR)-1-[3-(2-chlorophenyl)-2-(4-fluorophenyl)oxiran-2-ylmethyl]-1H-1, 2,4-triazole (IV) ##STR9## or e) a compound of the formula V ##STR10## in which the radicals are as defined below: R.sup.10 is fluorine or chlorine;
The invention furthermore relates to methods of controlling fungal pests using the compounds I and a compound II to V, or synergistic mixtures comprising them, and to the use of the compounds I, or the compounds II to V, for the preparation of such mixtures.
U.S. Pat. No. 5,240,940 and ACS Sympos. Ser. 443, page 538 to page 552 (1991) disclose compounds of the formula I, their fungicidal action and their preparation.
The literature (EP-A 253 213, EP-A 382 375, EP-A 398 692, EP-A 400 417) also discloses compounds of the formula II, their preparation and their action against fungal pests.
Also known are the pyrimidine derivatives III, their preparation and their action against fungal pests [R.sup.9 =methyl: DD-A 151 404 (common name: pyrimethanil); R.sup.9 =1-propynyl: EP-A 224 339 (common name: mepanipyrim); R.sup.9 =cyclopropyl: EP-A 310 550 (common name: cyprodinil)].
EP-A 196 038 discloses (2RS,3SR)-1-[3-(2-chlorophenyl)-2-(4-fluorophenyl)oxiran-2-ylmethyl]-1H-1, 2,4-triazole (IV) (INN name: epoxiconazole).
EP-A 318 704 (R.sup.10 =F, R.sup.11 =CF.sub.3), EP-A 206 999 (R.sup.10, R.sup.11 =--O--CF.sub.2 --O--: common name: fludioxonil) and EP-A 182 738 (R.sup.10, R.sup.11 =chlorine: common name: fenpiclonil) also disclose the compounds of the general formula V.
SUMMARY OF THE INVENTION
With a view to reducing the rates of application and to improving the spectrum of action of the known compounds, it is an object of the present invention to provide mixtures which have an improved activity against fungal pests while the total amount of active ingredients applied is reduced (synergistic mixtures).
We have found that this object is achieved by the mixtures defined at the outset. Moreover, it has been found that fungal pests can be controlled more efficiently when the compounds I and the compounds II to V are applied simultaneously, i.e. jointly or separately, or when the compounds I and the compounds II to V are applied in succession, than when the compounds I or II to V are used alone.
DETAILED DESCRIPTION OF THE INVENTION
Relative to the C.dbd.X double bond, the compounds of the formula II can exist in the E or the Z configuration (relative to the OCH.sub.3. and CO--YCH.sub.3 group
