摘要

In the method of protecting cultivated plants from the harmful effects of agrochemicals, quinoline derivatives of the formula IMAGE in which R1, R2 and R3 independently of one another are hydrogen, halogen, nitro, cyano, alkyl or alkoxy, R4, R5 and R6 independently of one another are hydrogen, halogen or alkyl, X is an aliphatic, acyclic, saturated hydrocarbon radical having 1 to 3 carbon atoms and Y is a carboxyl group, or a salt thereof, a mercaptocarbonyl group or a salt thereof, a carboxylic acid ester group, a carboxylic acid thiolester 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 X and Y together are an unsubstituted or substituted tetrahydrufuran-2-one ring, including acid addition salts and metal complexes thereof, a compositions containing such derivatives, are used. Novel quinoline derivatives and their preparation are also described.
