Compounds of the formula (I) or salts thereof, in each case in the optically active (3R,4R)-threo form, in which R1 is hydrogen or a hydrolysable radical, and (R2)n, (R3)m, n and m are as defined in formula (I) according to claim 1, where the stereochemical configuration at the carbon atom in position 3 of the butanoic acid derivative has a stereochemical purity of from 60 to 100% (R), preferably 70 to 100% (R), or more preferably 80 to 100% (R), in particular 90 to 100% (R), based on a mixture of threo enantiomers present, and the stereochemical configuration at the carbon atom in position 4 of the butanoic acid derivative has a stereochemical purity of from 60 to 100% (R), preferably 70 to 100% (R), more preferably 80 to 100% (R), in particular 90 to 100% (R), based on a mixture of threo enantiomers present, are suitable for use as herbicides and growth regulators, in particular for the selective use in plant crops, and can be prepared by the process of claim 9.
