Description

DESCRIPTION OF THE INVENTION [001] The present invention relates to a method for controlling a phytopathogenic fungus selected from Phakopsora spp., especially Phakopsora pachyrhizi and Phakopsora meibomiae, in soybeans, comprising treating the plants, their seeds or the soil with an effective amount as a fungicide of a composition comprising: I) mefentrifluconazole or the agriculturally acceptable salts thereof as compound (I); II) at least one compound (II) selected from the group comprising: benzovindiflupir, bixafen, boscalid, chlorothalonil, copper oxychloride, cyproconazole, difenoconazole, dimoxystrobin, fenpicoxamide, fenpropidine, fenpropimorph, fluindapir, fluoxastrobin, fluxapiroxad, inpirfluxam, cresoxim-methyl, mancozeb, mandestrobin, metiram, metominostrobin, methyltetraprol, quinofumelin, picoxystrobin, pidiflumetofen, prothioconazole, pyraclostrobin, tebuconazole, tetraconazole, trifloxystrobin, 1-(4,5-dimethylbenzimidazol-1-yl)-4,4,6-trifluoro-3,3-dimethyl-isoquinoline, 6-chloro-1-(4,5-dimethylbenzimidazol-1-yl)-4,4-difluoro-3,3-dimethyl-isoquinoline, 1-(4,5-dimethylbenzimidazol-1-yl)-4,4-difluoro-3,3-dimethyl-isoquinoline, 4,4-difluoro-3,3-dimethyl-1-(4-methylbenzimidazol-1-yl)isoquinoline, 1-(6-chloro-7-methyl-pyrazol[1,5-a]pyridin-3-yl)-4,4-difluoro-3,3-dimethyl-isoquinoline, 4,4-difluoro-1-(6-fluoro-7-methyl-pyrazol[1,5-a]pyridin-3-yl)-3,3-dimethyl-isoquinoline, 4,4-difluoro-3,3-dimethyl-1-(6-methylpyrazol[1,5-a]pyridin-3-yl)isoquinoline, 1-(6,7-dimethylpyrazol[1,5-a]pyridin-3-yl)-4,4-difluoro-3,3-dimethyl-isoquinoline, 1-(7,8-dimethylimidazo[1,2-a]pyridin-3-yl)-4,4-difluoro-3,3-dimethyl-isoquinoline, N’-(2,5-dimethyl-4-phenoxy-phenyl)-N-ethyl-N-methyl-formamidine and N’-[5-bromo-2-methyl-6-(1-methyl-2-propoxy-ethoxy)-3-pyridyl]-N-ethyl-N-methyl-formamidine and agriculturally acceptable salts thereof. [002] Mefentrifluconazole (I), its preparation and use in crop protection are described in document WO 2013/007767, which also discloses certain compositions with other active compounds. Due to the basic nature of its nitrogen atoms, mefentrifluconazole is capable of forming salts or adducts with inorganic or organic acids or with metal ions, in particular salts with inorganic acids. Mixtures of mefentrifluconazole are described in WO 2014/095994. [003] Mefentrifluconazole (I) comprises chiral centers and is generally obtained in the form of racemates. The R and S enantiomers of mefentrifluconazole (I) can be separated and isolated in pure form by methods known to those skilled in the art, for example, using chiral HPLC. [004] Therefore, in the method according to the present invention, mefentrifluconazole (I) can be used in the form of: - a racemic mixture of enantiomer (R) and enantiomer (S); - a mixture with any other proportions of enantiomer (R) and enantiomer (S); - pure enantiomer (R) or - pure enantiomer (S). [005] Mefentrifluconazole (I) may be supplied and used as enantiomer (R) with an enantiomeric excess (e.e.) of at least 40%, for example, at least 50%, 60%, 70% or 80%, preferably at least 90%, more preferably at least 95%, further 25%, preferably at least 98% and most preferably at least 99%. This applies to all compositions detailed herein. The enantiomer (R) of mefentrifluconazole has the chemical name: (R)-2-[4-(4-chlorophenoxy)-2-(trifluoromethyl)phenyl]-1-(1,2,4-triazol-1-yl)propan-2-ol. [006] Mefentrifluconazole (I) may also be supplied and used as enantiomer (S) with an enantiomeric excess (e.e.) of at least 40%, for example, at least 50%, 60%, 70% or 80%, preferably at least 90%, more preferably at least 95%, even more preferably at least 98% and most preferably at least 99%. This applies to all compositions detailed herein. The enantiomer (S) of mefentrifluconazole has the chemical name: (S)-2-[4-(4-chlorophenoxy)-2-(trifluoromethyl)phenyl]-1-(1,2,4-triazol-1-yl)propan-2-ol. [007] Compounds (II-1) to (II-29), as well as their pesticidal action and methods for producing them, are generally known (See: http://www.alanwood.net/pesticides/); these substances are commercially available. Compounds (II-30) to (II-38) are known from documents WO 2018/060039 and WO 2018/149851. Compounds (II-39) and (II-40) are known from documents EP 2865265, WO 2012/146125 and WO 2017/063973. [008] Agriculturally acceptable salts include especially salts of these cations or acid addition salts of those acids whose cations and anions, respectively, have no adverse effect on the fungicidal action of said compounds. Suitable cations are therefore, in particular, ions of alkali metals, preferably sodium and potassium, of alkaline earth metals, preferably calcium, magnesium and barium, of transition metals, preferably manganese, copper, zinc and iron, and also the ammonium ion which, if desired, may carry one to four C1-C4-alkyl substituents and/or a phenyl or benzyl substituent, preferably diisopropylammonium, tetramethylammonium, tetrabutylammonium, trimethylbenzylammonium, as well as phosphon
