Abstract: The present invention relates to novel fungicidal compositions for the treatment of phytopathogenic diseases of useful plants, especially phytopathogenic fungi, and to a method of controlling such phytopathogenic diseases on useful plants. In particular compositions suitable for control of diseases caused by phytopathogens comprise a mixture of a compound of formula (I) with flutianil; and a method of controlling diseases on useful plants using such compositions.

Abstract: The present invention relates to novel fungicidal two-component compositions based on metalaxyl having an R-enantiomer content of more than 70% by weight as one essential component and a second fungicidal component, for the treatment of phytopathogenic diseases of crop plants, especially phytopathogenic fungi, and to a method of combating phytopathogenic diseases on crop plants. The metalaxyl component is called active ingredient I.

Abstract: It has now been found that the use of: A) a N-sulfonyl-valine-amide of formula (I) wherein R1 is hydrogen, C1-4 alkyl, C3-6cycloalkyl or halophenyl, and R2 is C1-4 alkyl; in association with B) either compounds of formulae II to XII is particularly effective in combating or preventing fungal diseases of crop plants. These combinations exhibit synergistic fungicidal activity. Prominent examples for the compounds of formulae II to XII are: acibenzolar-S-methyl, azoxystrobin, chlorothalonil, cymoxanil, dimethomorph, fluazinam, fludioxonil, imazalil, S-imazalil, mancozeb, metalaxyl, metalaxyl-M, picoxystrobin, pyraclostrobin (BAS 500F) and trifloxystrobin.

Abstract: Metalaxyl having a high content of R-enantiomer of more than 70% by weight, or pure R-metalaxyl, in admixture with 4-[3-(4-chlorophenyl)-3-(3,4-dimethoxyphenyl)acryloyl]-morpholine (“dimethomorph”) or 3-anilino-5-methyl-5-(4-phenoxyphenyl)-1, 3-oxazolidine-2,4-dione (“famoxadone”), exhibits a clearly enhanced fungicidal action against plant diseases compared with a mixture of the same kind in which metalaxyl is used in the form of a racemate.

Abstract: When used in admixture with mancozeb, chlorothalonil, a copper salt, folpet, fluazinam or cymoxanil (it being possible for the latter to be used also together with one of the other five components), metalaxyl having a high R-enantiomer content of more than 70% by weight, or pure R-metalaxyl, exhibits a markedly increased fungicidal action against plant diseases as compared with a similar mixture in which metalaxyl is used in the form of the racemate.

Abstract: Metalaxyl having a high content of R-enantiomer of more than 70% by weight, or pure R-metalaxyl, in admixture with 4-[3-(4-chloropheny)-3-(3,4-dimethoxyphenyl)acryloyl]morpholine (“dimethomorpho”) or 3-anilino-5-methyl-5-(4-phenoxyphenyl)-1,3-oxazolidine-2,4-dione (“famoxadone”), exhibits a clearly enhanced fungicidal action against plant diseases compared with a mixture of the same kind in which metalaxyl is used in the form of a racemate.

Abstract: If the R-enantiomer of metalaxyl, furalaxyl or benalaxyl is used, this results in a markedly increased biodegradability of these plant fungicides in the soil and a higher activity on the plants, as compared with the data of the racemic active ingredients. Fungicidal compositions exhibiting said improved properties comprise either of these fungicides with a content of R-enantiomer of more than 70 percent by weight based on the total amount of active ingredient.
