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.

Microbicides

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.
