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 fungicida l component, for the treatment of phytopathogenic diseases of crop plants, especially phytopathogenic fungi, and to a method o f combating phytopathogenic diseases on crop plants. The metalaxyl component is called active ingredient (I). The following fungicide s may be used as the second component (II) of the mixture: either a compound (IIA), N-(3'-(1'-chloro-3-methyl 2'-oxopentan))-3,5-dichlo ro- 4-methylbenzamide (EP-600629); or a compound (IIB)(EP-253213) methyl (E)-2-methoxyimino-[2--(o- tolyloxymethyl)phenyl]acetate; or a (S)-valinamide of formula (IIC)(EP- 472(996); wherein R4 is isopropyl, and R5 is 4-methylphenyl, and wherein the asymmetri c center is preferably (R); or a compound (IID)(EP-5511048) (S)-1-anilino-4-methyl-2-methylthio-4-phenylimidazolin-5-one; or a compound (IIE), the Pseudomonas fluoresens strain, ATCC accesion No. 55169 (USP-5,348,742) is particularly effective incombating or preventin g fungal diseases of crop plants. These combinations exhibit synergistic fungicidal activity.
