A new fungicidal mixture contains synergistic amounts of (1) prothioconazole (I) and (2) at least one of 20 other specific fungicides, e.g. boscalid, carboxine, metrafenone, quinoxyfen, fenoxanil, carbendazim, metalaxyl, prochloraz or anthraquinone. A fungicidal mixture contains synergistic amounts of the following active components: (1) prothioconazole (I) or its salt or adduct; and (2) one or more of boscalid, carboxine, metrafenone, N-(alpha -cyclopropoxyimino)-(2,3-difluoro-6-trifluoromethyl-benzyl)-phenylacetamide, N-(alpha -cyclopropoxyimino)-2,3-difluoro-6-difluoromethyl-benzyl)-phenylacetamide, quinoxyfen, dithianon, thiram, mepiquat chloride, cyazofamid, fenoxanil, 6-fluoro-2-(1-(2-(isopropoxycarbonylamino)-isovaleramido)-ethyl)-benzothiazole, thiophanate methyl, carbendazim, metalaxyl, fludioxonil, thiabendazole, quintozen, prochloraz and/or anthraquinone. Independent claims are included for: (a) a harmful fungus control method involving application of the mixture of (1) and (2) to the fungi, their habitat or plants, seeds, soil, surfaces, materials or regions to be protected ((1) and (2) being applied simultaneously, separately or successvely); and (b) a fungicidal composition comprising the (1)/(2) mixture together with a solid or liquid carrier. ACTIVITY : Fungicide. In tests for protective action against Blumeria graminis f. sp. triciti (mildew) in wheat, prothioconazole (I) at 1 ppm alone or boscalid (II) at 4 ppm alone gave no (0%) control, whereas a combination of 1 ppm (I) and 4 ppm (II) gave 92% control. MECHANISM OF ACTION : None given in the source material.
