Abstract

##STR1## where R.sup.1 is hydrogen or fluorine, PA0 R.sup.2 is halogen, PA0 R.sup.3 is hydrogen, halogen or a C.sub.1 -C.sub.4 -alkyl, PA0 R.sup.4, R.sup.5 are hydrogen, C.sub.1 -C.sub.8 -alkyl, C.sub.2 -C.sub.4 -alkyl which carries a hydroxyl, C.sub.1 -C.sub.4 -alkoxy or C.sub.1 -C.sub.4 -alkylthio radical, C.sub.1 -C.sub.6 -alkoxy, C.sub.3 -C.sub.6 -alkenyl, C.sub.3 -C.sub.6 -alkynyl, C.sub.3 -C.sub.6 -alkenyloxy and/or C.sub.3 -C.sub.6 -alkynyloxy, or together with the nitorgen atom form a 5- or 6-membered aliphatic ring in which a methylene group may be replaced by an oxygen atom, and PA0 R.sup.6 is hydrogen, C.sub.1 -C.sub.6 -alkyl which is unsubstituted or substituted by one or two C.sub.1 -C.sub.4 -alkoxy groups, or is C.sub.3 -C.sub.6 -alkenyl, C.sub.3 -C.sub.6 -alkynyl or benzyl, processes for their manufacture, and their herbicidal use.
