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.
Claims11
A fungicidal composition comprising synergistic fungicidally effective amounts of (I) metalaxyl, wherein more than 70% by weight of the metalaxyl is the R-enantiomer, and (IIC), a copper salt, wherein the ratio by weight of I:IIC ranges from 10;1 to 1:100, and an inert carrier.
A method of controlling and preventing Oomycetes infestation in plants, parts of plants, or at the site of their growth, which comprises applying thereto synergistic fungicidally effective amounts in any desired sequence, simultaneously or in immediate succession, (I) metalaxyl, wherein more than 70% by weight is the R-enantiomer and (IIC), a copper salt, wherein the ratio by weight of I:IIC ranges from 10:1 to 1:100.
