摘要

O.Z. 0050/41605 N-Aryltetrahydrophthalimides I I where X is hydrogen or halogen; R1 is C1-C4-alkyl which may carry from one to five halogen atoms or one of the groups stated for X; R2 is a heteroaromatic structure bonded via a nitrogen atom, which has a 5-membered ring and contains, in addition to carbon ring members, from one to three nitrogen atoms, and R3 is halogen, C1-C4-alkylthio, one of the groups stated for R2 or phenylthio which in turn may carry from one to three of the following radicals: halogen, C1-C4-alkyl, C1-C4-haloalkyl, C1-C4-alkoxy, C1-C4-haloalkoxy or C1-C4-alkylthio, and where the phenylthio group may also carry halogen atoms such that the total number of radicals is 4 or 5, and salts thereof which can be used in agriculture, are suitable as herbicides.
