USE OF QUINOLINE DERIVATIVES FOR IMPROVING PLANT YIELD

摘要

Compounds (A) can be used for increasing the yield of useful plants or crop plants with respect to their harvested plant organs, wherein the Compound (A) is selected from compounds of the formula (I) and hydrates or salts thereof, in which RB 1 is halogen, (C1-C4)-alkyl, (C1-C4)-alkoxy, nitro or (C1-C4)-haloalkyl; nB is a natural number from 0 to 5, preferably 0 to 3; RB 2 is ORB 3, SRB 3 or NRB 3RB 4 or a saturated or unsaturated 3- to 7-membered heterocycle having at least one nitrogen atom and up to 3 heteroatoms, preferably from the group consisting of O and S, which 1 is attached via the nitrogen atom to the carbonyl group in (S2) and which is unsubstituted or substituted by radicals from the group consisting of (C1-C4)- alkyl, (C1-C4)-alkoxy and optionally substituted phenyl, preferably a radical of the formula ORB 3, NHRB 4 or N(CH3)2, in particular of the formula ORB 3; RB 3 is hydrogen or an unsubstituted or substituted aliphatic hydrocarbyl radical, preferably having a total of 1 to 18 carbon atoms; RB 4 is hydrogen, (C1-C6)-alkyl, (C1-C6)-alkoxy or substituted or unsubstituted phenyl; TB is a (C1- or C2)-alkanediyl chain which is unsubstituted or substituted by one or two (C1-C4)-alkyl radicals or by [(C1-C3)-alkoxy]carbonyl;preferably 1-methylhexyl (5-chloro-8-quinolinoxy)acetate ("cloquintocet-mexyl").
