摘要

In the present invention there is disclosed a two- or three-component fungicidal agent based on metalaxyl having a high R-enantiomer content of more than 70 percent by weight of (I), and further as another component the agent contains IIA) mancozeb, IIB) chlorothalonil, IIC) a copper salt or hydroxide, IID) folpet, IIE) fluazinam or IIF) cymoxanil. If the component IIF is used it may be also present: a third component being selected from a group comprising the components IIA and IIE. Weight ratio of the components I:II ranges between 10:1 to 1:100. In the present invention there is also claimed a method of controlling and preventing Oomycetes infestation in plants or at the site of their growth, which comprises applying thereto in a synergistic fungicidally effective amount, in any desired sequence, simultaneously or in immediate succession of the aforementioned active substances in specified weight ratios.
