Liquid herbicidal agents which contain a compound of the formula <IMG> in the form of the racemate or of the L enantiomer, lower alkyl esters thereof or salts thereof with acids or bases (I) in combination with surfactants in the form of a) alkyldimethyl-, fatty acid amidopropyldimethyl- or fatty acid amido ethyldimethylamine oxides or b) the betaine of coconut alkyldimethylaminoacetic acid or of coconut alkylaminopropionic acid or c) alkanesulfonates and mixtures thereof with fatty alcohol polyglycol ether sulfosuccinic acid monoesters or fatty alcohol polyglycol ether sulfates or d) alkylsulfosuccinic acid monoesters or fatty alcohol polyglycol ether sulfosuccinic acid monoesters and fatty alcohol polyglycol ether sulfosuccinic esters and their mixtures with fatty alcohol polyglycol ether sulfates or e).alpha.-olefinsulfonates and mixtures thereof with fatty alcohol polyglycol ether sulfates, fatty alcohol polyglycol ether sulfosuccinic acid monoesters or alkylsulfosuccinic acid monoesters, sulfonates which can be used being alkali metal salts, ammonium salts, alkaline earth metal salts or substituted alkyl- or alkanolamine salts of the corresponding sulfonic or sulfuric acids, which possess improved herbicidal activities, high low-temperature stability and rain resistance and are distinguished by a low content of organic solvents.
