Abstract

Aminopyrazinones and aminotriazinones of the formula ##STR1## and the salts of these compounds with amines, alkali metal or alkaline earth metal bases or quaternary ammonium bases have good pre- and post-emergent selective herbicidal and growth-regulating properties. In this formula, E is nitrogen or .dbd.CR.sup.4 --, R.sup.1 is C.sub.1 -C.sub.4 -alkyl, R.sup.2 is hydrogen, C.sub.1 -C.sub.3 -alkyl, C.sub.1 -C.sub.3 -halogenoalkyl, C.sub.1 -C.sub.3 -alkoxy, C.sub.1 -C.sub.3 -halogenoalkoxy, C.sub.1 -C.sub.3 -alkylthio, C.sub.1 -C.sub.3 -alkylsulfinyl, C.sub.1 -C.sub.2 -alkoxyethoxy, C.sub.1 -C.sub.3 -alkylsulfonyl, halogen or --NR.sup.5 R.sup.6, R.sup.3 is hydrogen or C.sub.1 -C.sub.3 -alkyl and Q is a group ##STR2## in which R.sup.4 is hydrogen, C.sub.1 -C.sub.3 -alkyl, C.sub.1 -C.sub.3 -halogenoalkyl, C.sub.1 -C.sub.3 -alkoxy, cyclopropyl, C.sub.1 -C.sub.3 -halogenoalkoxy, C.sub.1 -C.sub.3 -alkylthio, C.sub.2 -C.sub.4 -alkoxyalkyl, C.sub.3 -C.sub.5 -dialkoxymethyl, halogen or --NR.sup.5 R.sup.6, R.sup.5 and R.sup.6 independently of one another are hydrogen or C.sub.1 -C.sub.3 -alkyl, X is oxygen or sulfur and A is a group ##STR3## in which Y is oxygen, sulfur, --CH.dbd.CH--, --NR.…
