HERBICIDAL AGENTS

摘要

1. A herbicidal agent which contains an active ingredient of the formula I or its salt see diagramm : EP0223029,P10,F3 wherein R denotes hydrogen or alkyl which is optionally monosubstituted or polysubstituted by halogen, hydroxyl, (C1 -C4 )-alkoxy or (C1 -C4 )-alkoxycarbonyl, in combination with a compound of the formula II or its salt see diagramm : EP0223029,P11,F1 wherein R**1 denotes (C1 -C4 )-alkyl, (C2 -C6 )alkenyl or (C2 -C6 )alkynyl, each of which can be halogenated (C1 -C4 )alkylamino, di-(C1 -C4 -alkyl)-amino, [N-(C1 -C4 -alkylsulfonyl)-N-(C1 -C4 )]-amino, wherein the alkyl radicals can be halogenated, phenyl, benzyl, phenoxy, pyrazolyl or thienyl, all of which can be substituted by (C1 -C4 )-alkyl, (C2 -C6 )-alkenyl, (C2 -C6 )-alkynyl or (C1 -C4 )-alkoxy, all of which can be substituted by halogen or (C1 -C4 -alkoxy)-carbonyl, or by halogen, CF3 , nitro, a radical of the formula -COOR**4 , wherein R**4 denotes H, (C1 -C4 )-alkyl, (C2 -C6 )-alkenyl, (C2 -C6 )-alkynyl, (C1 -C4 )-alkoxy-(C1 -C4 )-alkyl or halogeno-(C1 -C4 )-alkyl, or by a radical of the formula -S(O)n R**5 , wherein R5 denotes (C1 -C4 )-alkyl, (C1 -C4 )-alkoxy, halogeno-(C1 -C4 )-alkyl, (C1 -C4 )-alkoxy-(C1 -C4 )-alkyl, (C1 -C4 )-alkoxycarbonyl-(C1 -C4 )-alkyl, di-(C1 -C4 -alkyl)-amino, (C1 -C4 )-alkylamino or (C1 -C4 )-alkoxy-(C1 -C4 )-alkylamino and n denotes 0, 1 or 2, R**1' denotes H, (C1 -C4 )-alkyl or (C1 -C4 )-alkenyl, R**2 and R**3 independently of one another denote (C1 -C4 )-alkyl or (C1 -C4 )-alkoxy, both of which are optionally monosubstituted or polysubstituted by halogen, (C1 -C4 )-alkoxy or (C1 -C4 )-alkoxycarbonyl, or denote (C2 -C6 )-alkenyl, (C2 -C6 )-alkynyl, (C2 -C6 )-alkenyloxy, (C2 -C6 )-alkynyloxy or halogen, X denotes O, S or NR**6 in which R**6 denotes (C1 -C4 )-alkyl or (C1 -C4 )-alkoxy, and Z denotes CH or N, with the exception of compounds in which R**1 = ortho-2-[(C1 -C4 -alkoxy)-carbonyl]-phenyl, R**1' = H and R**2 and R**3 = (C1 -C2 )-alkyl or (C1 -C2 )-alkoxy.
