ABSTRACT:
Herbicidally effective aminoalkyl esters of 2-nitro-5-(o-chloro-p-trifluoromethylphenoxy)-benzoic acid, and acid addition salts and quaternary ammonium salts thereof, are suitable for the selective control of weeds in crops of useful plants, for example soya bean and rice crops.
The aminoalkyl esters correspond to the formula ##STR1## wherein A is a C.sub.2 -C.sub.4 -alkylene bridge or the direct bond, and ##STR2## is an open amino group, and ##STR3## is a cyclic amino group.
