Alkylidenehydrazinophenylsulfonylureas, processes for their preparation and their use as herbicides and plant growth regulators

摘要

Compounds of the formula (I) and salts thereof in which R1 to R6, W, X, Y and Z are defined as in claim 1, have herbicidal or plant growth-regulatory properties. They can be prepared by processes analogous to known processes (cf. claim 5), in some cases via novel intermediate products (cf. formula II):
