Use of quinoline derivatives for the protection of cultivated plants from herbicides

A composition for protecting cultivated plants from the harmful effects of herbicidal agrochemicals, which contains, as the active component, an effective amount of a compound of the formula I ##STR149## in which R.sub.1, R.sub.2, R.sub.4, R.sub.5 and R.sub.6 are hydrogen,

• R.sub.3 is hydrogen or chlorine,
• X is --CH.sub.2 -- or --CH(CH.sub.3)--, and
• Y is --COOR.sub.7 or --COSR.sub.8, wherein
• R.sub.7 is hydrogen or C.sub.1 -C.sub.18 -alkyl;
• C.sub.1 -C.sub.10 -alkyl which is substituted by one to three halogen-atoms, or one substituent selected from the group nitro, cyano, hydroxyl, C.sub.1 -C.sub.8 -alkoxy, C.sub.1 -C.sub.4 -alkoxyethoxy, C.sub.2 -C.sub.6 -hydroxyalkoxy, C.sub.2 -C.sub.6 -hydroxyalkylthio, C.sub.1 -C.sub.4 -alkoxycarbonyl, C.sub.2 -C.sub.4 -dialkylamino or phenoxy;
• C.sub.1 -C.sub.6 -alkyl, which is substituted by phenyl, tetrahydrofuranyl, tetrahydropyranyl, furanyl, pyridinyl or phenyl which is substituted by C.sub.1 -C.sub.3 -alkoxy;
