Case 5-15263/1+2 Use of quinoline derivatives for the protection of cultivated plants Abstract The use of quinoline derivatives of the formula Image wherein R1, R2 and R3 independently of one another are each hydrogen, halogen, nitro, cyano, C1-C3-alkyl or C1-C3-alkoxy, R4, R5 and R6 independently of one another are each hydrogen, halogen or C1-C3-alkyl, A is any one of the groups -CH2-, -CH2CH2- or -CH(CH3)-, and Z a) is cyano or amidoxime, which can be acylated on the oxygen atom, or b) is a carboxyl group or a salt thereof, a mercapto- carbonyl group or a salt thereof, a carboxylic acid ester group, a carboxylic acid thiol ester group, an unsubstituted or substituted carboxylic acid amide group, a cyclised, unsubstituted or substituted derivative of a carboxylic acid amide group, or a carboxylic acid hydrazide group, or A and Z together form an unsubstituted or substituted tetrahydrofuran-2-one ring; with the inclusion of the acid addition salts and metal complexes thereof, for the protection of cultivated plants against the harmful effects of herbicidally active 2-[4-(5-chloro-3-fluoropyridin-2-yloxy)-phenoxy]-propionic acid derivatives. The aforementioned herbicidal 2-[4-(5-chloro-3-fluoro- pyridin-2-yloxy)-phenoxy]-propionic acid derivatives correspond to the formula Image wherein Y is a group -NR16R17, -O-R18, -S-R18 or -O-N=CR19R20, R16 and R17 independently of one another are each hydrogen, C1-C8-alkoxy, C1-C8-alkyl, phenyl or benzyl, R16 and R17 together with the nitrogen atom carrying them form a 5- or 6-membered saturated nitrogen heterocycle which can be interrupted by an oxygen or sulfur atom, R18 is hydrogen or the equivalent of an alkali metal, alkaline-earth metal, copper or iron ion; or is a quaternary C1-C4-alkylammonium or C1-C4-hydroxyalkyl- ammonium radical; a C1-C9-alkyl radical which is unsubstituted or mono- or polysubstituted by amino, halogen, hydroxyl, cyano, nitro, phenyl, C1-C4- alkoxy, polyethoxy having 2 to 6 ethylene oxide units, -COOR21, -COSR21, -CONH2-, -CON(C1-C4-alkoxy)- C1-C4-alkyl, -CO-N-di-C1-C4-alkyl, -CONH-C1-C4-alkyl, -N(C1-C4-alkoxy)-C1-C4-alkyl or di-C1-C4-alkylamino; or is a C3-C9-alkenyl radical which is unsubstituted or substituted by halogen or C1-C4-alkoxy; or is a C3-C9-alkynyl radical which is unsubstituted or substituted by halogen or C1-C4 alkoxy; or is C3-C9- cycloalkyl; or phenyl which is unsubstituted or substituted by cyano, C1-C4-alkyl, C1-C4-alkoxy, acetyl, -COOR21, -COSR21, -CONH2, -CON(C1-C4-alkoxy)-C1-C4-alkyl, -CO-N-di-C1-C4-alkyl or -CONH-C1-C4-alkyl, R19 and R20 independently of one another are each C1-C4- alkyl, or together form a 3- to 6-membered alkylene chain, and R21 is hydrogen, C1-C6-alkyl, C1-C6-haloalkyl, C2-C6- alkoxyalkyl, C3-C6-alkenyl, C3-C6-haloalkenyl, C3-C6-alkynyl or C3-C6-haloalkynyl.
