Abstract

##STR1## where X is hydrogen or halogen; PA1 R.sup.1 is C.sub.1 -C.sub.4 -alkyl which may carry from one to five halogen atoms or one of the groups stated for X; PA1 R.sup.2 is a heteroaromatic structure bonded via a nitrogen atom, which has a 5-membered ring and contains, in addition to carbon ring members, from one to three nitrogen atoms, and PA1 R.sup.3 is halogen, C.sub.1 -C.sub.4 -alkylthio, one of the groups stated for R.sup.2 or phenylthio which in turn may carry from one to three of the following radicals: halogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -haloalkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkoxy or C.sub.1 -C.sub.4 -alkylthio, and where the phenylthio group may also carry halogen atoms such that the total number of radicals is 4 or 5, and salts thereof which can be used in agriculture, are suitable as herbicides. 2
