    Abstract: The present invention relates to a process for preparing trioxime derivatives of the formula I in which the substituents R 1 and R 2 are identical or different and each is cyano, alkyl, haloalkyl or cycloalkyl, and R 3 and R 4 are identical or different and each is alkyl, haloalkyl, cycloalkyl, alkylcarbonyl or arylalkyl, by the following reaction steps in water without isolation of the intermediates: A) nitrosation of 1,3-diketones of the formula II to give monooximes of the formula III, B) oximation of III with hydroxylamine derivatives of the formula IV H 2 N-OR 3' IV in which R 3' is hydrogen or a group R 3 to give bisoximes of the formula V, C) alkylation of V with alkylating agents or acylation of V with acylating agents to give compounds of the formula VI and D) subsequent oximation of VI with hydroxylamine to give compounds of the formula I.

    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.
