Abstract

Compounds of the formula I or their salts ##STR1## in which R.sup.1 to R.sup.6, W, X, a and b are as defined in claim 1 and L is a heterocyclic or isocyclic aromatic radical having 5 to 6 ring atoms, which can be condensed with an aromatic or non-aromatic 5- or 6-membered ring, where the radical can be unsubstituted or substituted, and a, b and c independently of one another are 0 or 1, are suitable as herbicides, plant growth regulators and fungicides. They can be prepared by the processes defined herein, it being possible in some cases to use novel intermediates.
