Abstract

A combination of a variety of herbicides with safening agents which are substituted 1,8-naphthyridines of the formula ##STR1## where R.sup.1 is mercapto, hydroxyl, halogen, benzylthio, amino or NR.sup.2 R.sup.3, where PA0 R.sup.2 is a group ##STR2## where A is C.sub.1 -C.sub.8 -alkyl, R.sup.3 is hydrogen, XR.sup.4, where X is oxygen or sulfur and R.sup.4 is C.sub.1 -C.sub.12 -alkyl, PA0 R.sup.5 and R.sup.7 are each hydrogen, C.sub.1 -C.sub.12 -alkyl, hydroxyl, halogen, mercapto, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -alkylthio, dialkylamino where each alkyl is of 1 to 6 carbon atoms, phenoxy or phenylthio, halo-(C.sub.1 -C.sub.3)-alkyl, C.sub.1 -C.sub.4 -alkoxy-(C.sub.1 -C.sub.3)-alkyl, and PA0 R.sup.6 is hydrogen, C.sub.1 -C.sub.12 -alkyl, carboxyl or C.sub.1 -C.sub.4 -alkoxycarbonyl or the plant-tolerated salts thereof.
