摘要:
The invention relates to crop protection agents which comprise an active substance combination of herbicide and safener. The herbicides are selected from the group comprising the ALS inhibitors (ALS=acetolactate synthase) such as sulfonylureas, imidazolines, triazolopyrimidinesulfonamides, pyrimidyloxypyridinecarboxylic acid derivatives and pyrimidyloxybenzoic acid derivatives. The safeners are compounds of the formula I ##STR1## which are as defined in claim 1, where Z and Y are N or CH, it being possible for H to be replaced by X, X is H, Hal, haloalkyl or -alkoxy, alkyl, alkoxy, alkylthio, NO.sub.2, NH.sub.2, CN, alkylsulfonyl, A is alkylene or alkenylene, B is carboxyl or a derivative of the carboxyl group. The mixtures are mainly suitable for controlling harmful plants in the crops maize and cereals.

摘要:
Compounds of formula (I), where R.sup.1, R.sup.2, n, W, R.sup.3 and A are as defined in claim 1, are suitable for use as herbicides and plant growth regulators. They can be produced by a process similar to known processes. To produce them, new compounds of formula (II) are reacted with a carbamate of formula R.sup.* --O--CO--NR.sup.3 A, where R.sup.3 stands for phenyl or alkyl. The compounds of formula (II) can be obtained from the corresponding sulphochlorides.
