Abstract

The present invention relates to a herbicidal composition comprisingA) one or more sulfonylureas of the formula (I) and/or their salts in whichR1 is C2-C4-alkoxy or CO—Ra, where Ra is OH, C1-C6-alkoxy or NRbRc, where Rb and Rc independently of one another are identical or different and are H or C1-C6-alkyl,R2 is halogen or (A)n—NRdRe, where n is zero or 1, A is a group CRfRg, where Rf and Rg independently of one another are identical or different and are H or C1-C6-alkyl, Rd is H or C1-C6-alkyl and Re is H, C1-C6-alkyl or an acyl radical, where Rd and Re may also form a heterocyclic ring and where, if R1 is C2-C4-alkoxy, R2 may also be H,R3 is H or C1-C6-alkyl,m is zero or 1,X and Y independently of one another are identical or different and are C1-C6-alkyl, C1-C6-alkoxy or C1-C6-alkylthio, where each of the three radicals mentioned is unsubstituted or substituted by one or more radicals selected from the group consisting of halogen, C1-C4-alkoxy and C1-C4-alkylthio, or are C3-C6-cycloalkyl, C2-C6-alkenyl, C2-C6-alkynyl, C3-C6-alkenyloxy or C3-C6-alkynyloxy, preferably C1-C4-alkyl or C1-C4-alkoxy,Z is CH or N, andB) one or more surfactants comprising as structural eleme…
