Abstract

Pyridine-2,3-dicarboximides of the formula I ##STR1## where R.sup.1, inter alia, is hydrogen or alkoxy; PA2 at least one radical R.sup.2, R.sup.3, or R.sup.4 is nitro or OR.sup.5 or NR.sup.6 R.sup.7 group; PA1 R.sup.5, inter alia, is hydrogen or C.sub.1 -C.sub.4 -alkylcarbonyl; PA1 R.sup.6, inter alia, is hydrogen or C.sub.1 -C.sub.4 -alkyl; and their agriculturally utilizable salts are described.
