    Abstract: The present invention relates to a process for the preparation of 1,2,4-triazol-1-ylmethyloxiranes of the formula I in which A and B are identical or different and, independently of one another, are C 1 -C 4 -alkyl, phenyl-C 1 -C 2 -alkyl, C 3 -C 6 -cycloalkyl, C 3 -C 6 -cycloalkenyl, tetrahydropyranyl, tetrahydrofuranyl, dioxanyl or phenyl, where the phenyl radical can carry one to three substituents chosen from the group: halogen, nitro, C 1 -C 4 -alkyl, C l -C 4 -alkyloxy, phenoxy, amino, C 1 -C 2 -haloalkyl or phenylsulfonyl, which comprises reacting a) an oxirane of the formula II in which A and B have the meanings given above and L is a nucleophilically substitutable leaving group, with 4-amino-1,2,4-triazole of the formula III to give 4-amino-1,2,4-triazolium salts of the formula IV and b) deaminating the 4-amino-1,2,4-triazolium salts IV with alkali metal nitrites and acid or organic nitrites to give 1,2,4-triazol-1-ylmethyloxiranes of the formula I, and to 4-aminotriazolium salts of the formula IV as intermediates.

    Abstract: New fungicidal mixtures contain dithianon (I) and at least one 1,2,4-triazole derivative (II) in synergistic amounts, where (II) is metconazole, epoxiconazole, fluquinconazole, tebuconazole (IIa), tetraconazole, difenconazole and/or prothioconazole (preferably metconazole, epoxiconazole or (IIa)). Independent claims are included for: (1) a fungicidal composition comprising the (I)/(II) mixture plus a solid or liquid carrier; and (2) a method for controlling harmful fungi, by applying (I) and (II) to the fungi, their habitat or plants, seeds, soil, surfaces, materials or regions to be protected. ACTIVITY : Fungicide. In tests against Botrytis cinerea in paprika seedlings, (I) at 16 ppm or (IIa) at 4 ppm gave no control, whereas a combination of 16 ppm (I) and 4 ppm (IIa) gave 59% control. MECHANISM OF ACTION : Synergist.

    Abstract: Fungicidal mixtures, comprising A) the compound of the formula I B) a biphenylamide of the formula II, in which Z is a pyridyl ring or a five-membered heteroaryl ring which, in addition to carbon atoms, contains one or two nitrogen atoms or one nitrogen atom and one oxygen or sulfur atom, where Z carries one to three identical or different substituents from the group consisting of halogen, methyl and trifluoromethyl, and X is halogen, in a synergistically effective amount, methods for controlling harmful fungi using mixtures of the compounds I and II and the use of the compounds I and II for preparing such mixtures are described.
