Claim:
A method of controlling plant pathogens, comprising applying an effective amount of a compound of formula (I) or a salt thereof, wherein X is selected from among H, OR 1 , SR 1 , NR 1 R 2 , N(OR 1 )(R 2 ), N(R 1 )—NR 1 NR 2 or N(R 1 R 2 R 3 ) + A − , Y is selected from among OR 1 , O − Cat + or NR 1 R 2 , Z is selected from among O, S, NR 1 , NOR 1 , N—CN or N—NR 1 R 2 , R is a substituent selected from the group consisting of (i) an unsubstituted or mono- or polysubstituted (C 3 -C 22 )-alkyl radical, (ii) an unsubstituted or mono- or polysubstituted (C 3 -C 22 )-alkenyl radical, (iii) an unsubstituted or mono- or polysubstituted (C 3 -C 22 )-alkynyl radical, (iv) an unsubstituted or mono- or polysubstituted —(CH 2 ) m -spermine radical, (v) an unsubstituted or mono- or polysubstituted —(CH 2 ) m -spermidine radical, (vi) an unsubstituted or mono- or polysubstituted N-methylated —(CH 2 ) m -sperm(id)ine radical, where m is in each case an integer from 1 to 4 and where the one or the plurality of substituents in the abovementioned radicals (i) to (vi) can be selected independently of one another from among group α, consisting of a (C 1 -C 6 )-alkyl radical, a (C 1 -C 6 )-thioalkyl radical, a (C 3 -C 7 )-cycloalkyl radical which can have one or more hetero atoms such as, for example, O or S, a (C 1 -C 6 )-alkoxy radical, a hydroxyl group, a trifluoromethyl group, a triazole group, bromine, chlorine, fluorine, an unsubstituted, mono- or disubstituted phenyl, phenoxy, benzyl, benzyloxy, naphthyl or naphthoxy radical, and (vii) an ethyleneoxy group selected from among: —CH 2 [OCH 2 CH 2 ] n —OH, —CH 2 [OCH 2 CH 2 ] n —OMe, —CH 2 —CH 2 —[OCH 2 CH 2 ] n —OH —CH 2 —CH 2 —[OCH 2 CH 2 ] n —OMe —CH 2 —CH 2 —CH 2 —[OCH 2 CH 2 ] n —OH —CH 2 —CH 2 —CH 2 —[OCH 2 CH 2 ] n —OMe —CH 2 —CH 2 —CH 2 —CH 2 —[OCH 2 CH 2 ] n —OH or —CH 2 —CH 2 —CH 2 —CH 2 —[OCH 2 CH 2 ] n —OMe, where n=1-20, R 1 , R 2 and R 3 independently of one another are selected from the group consisting of hydrogen, a (C 1 -C 6 )-acyl radical, —CONH 2 , —(CO)—(CH 2 ) 0-6 —COOH, a lactyl radical, a (C 1 -C 6 )-alkyl radical, a (C 3 -C 7 )-cycloalkyl radical which may contain one or more hetero atoms selected from the group consisting of O and S, an unsubstituted, mono- or disubstituted phenyl, benzyl or naphthyl radical whose substituents can be selected from among group α, A − is an anion selected from among halide, chlorate or carboxylate, Cat + is a monovalent or divalent cation, the stereoisomeric center at C5, if present, is present in the R or S form or as a racemate, and the C2-C3 double bond is present in the E or Z form; to a plant, a part of the plant or the soil in which the plant grows, wherein the plant pathogenis an oomycete.
