Synergistically increased effects against undesirable plant growth are achieved by a combined application of an active substance of the type A with an active substance of the type B, where type A represents the herbicides glufosinate (A1), glyphosate (A2), or salts thereof, and type B represents sulfonyl ureas of the formula (B) (see fig I) where R1 ~is a radical from the group comprising 2-ethoxy- phenoxy, 2-propoxyphenoxy, 2-isopropoxyphenoxy, 2-methoxycarbonylphenyl, 3-(dimethylaminocarbonyl)- pyrid-2-yl, 3-ethylsulfonylpyrid-2-yl, 3-[N-(C1-C4- alkyl)-N-(C1-C4-alkylsulfonyl)amino]pyrid-2-yl, (N- methyl-N-methylsulfonyl)aminosulfonyl, 2-(2-chloro-~ ethoxy)phenyl, 2-(methoxycarbonyl)phenyl, 2-(meth- oxycarbonyl)thien-3-yl, R2 ~is H or methyl, R3 ~and R4 independently of one another are C1-C2-alkyl, C1-C2-alkoxy or C1-C2-haloalkoxy and X ~is CH or N, or salts thereof, with the exception of the application of combinations of a compound of the formula (A2) with one or more compounds of the formula (B) in which a) R1 is 2-methoxycarbonylphenyl, R2 is H or methyl and R3 is methyl, R4 is methoxy and X is N, and b) R1 is 2-(methoxycarbonyl)thien-3-yl, R2 is H, R3 is methyl, R4 is methoxy and X is N.
