摘要

Disclosed are herbicidally active benzoyl derivatives of the formula (I), wherein R1 is nitro, C1-C6-alkyl, C1-C6-haloalkyl, C1-C6-alkoxy, C1-C6-alkylsulphonyl or C1-C6-haloalkylsulphonyl; R2 is nitro, halogen, C1-C6-alkyl, C1-C6-haloalkyl, C1-C6-alkylthio, C1-C6-alkylsulphynyl, C1-C6-alkylsulphonyl or C1-C6-haloalkylsulphonyl; Y is CR13R14; R13 and R14 are hydrogen, C1-C4-alkyl, C1-C4-haloalkyl, C1-C4-alkoxycarbonyl, C1-C4-haloalkoxycarbonyl or CONR7R8, where R7 has the meaning of hydrogen or C1-C4-alkyl and R8 has the meaning of C1-C4-alkyl; R15 is a pyrazole of the formula (II) which is linked in the 4-position, where R16 is C1-C6-alkyl; and their agriculturally useful salts; process and intermediates for their preparation; compositions comprising them; and use of said derivatives and compositions as herbicides.
