| 摘要 |
The invention relates to substituted 6-aryl-3-thioxo-5-(thi)oxo-2,3,4,5-tetrahydro-1,2,4-triazines of formula (I) and to their salts. In said formula, R<1> is C1-C6-alkyl, C1-C6-halogen alkyl, and possibly substituted phenyl; R<2> is NH2, C1-C6-alkyl, C1-C6-halogen alkyl, C2-C6-alkenyl, C3-C6-alkinyl, (C1-C6-alkoxy) carbonyl-C1-C6-alkyl, C1-C6-alkoxy-C1-C6-alkyl, C1-C6-alkylthio-C1-C6-alkyl, C3-C6-cycloalkyl; Ar is a group corresponding to formula (Ar<1>), (Ar<2>), (Ar<3>) or (Ar<4>); Y is O, S; Z is O, S, NH, N(C1-C6-alkyl) and R<3>, R<4>, R<5>, R<6>, R<7> and R<8> have the meaning given in the description. Said compounds are used as herbicides and for the desiccation/defoliation of plants. |
