According to the invention, the fungicidal composition for controlling parasitic fungi in plants consists in that, in order to obtain a superior fungicidal effect, 20-70% by weight of wettable powder are combined, phosphonic acid monoesters or salts of these monoesters having the general formula I wherein R represents a linear or branched alkyl radical, optionally halogenated or nitrated, containing from 1 to 18 carbon atoms, an optionally halogenated alkenyl or alkynyl radical, a alkyl or alkenyl-alkyl radical, the hydrocarbon portion of these four radicals containing from 1 to 8 carbon atoms, a cyclohexyl radical, an aryl radical, especially optionally substituted phenyl, or a linked heterocyclic radical by oxygen through an aliphatic chain containing 1 to 3 carbon atoms, in particular tetrahydrofurfuryl, M represents a hydrogen atom, an ammonium cation substituted with 1-4 alkyl, hydroxy chlorine with 1 ... 3 carbon atoms, 1 or 2 radicals .... |
