The invention relates to a novel herbicide composition, which comprises the (S) enantiomer or racemate of a compound of the general formula (I), ##STR1## wherein R stands for a methyl or ethyl group, as active ingredient in an amount of 0.01 to 95% by weight together with one or more solid and/or liquid carrier(s), preferably grist(s) of native or synthetic material(s) and/or with inert solvents(s), preferably xylene(s) and/or cyclohexanone; and optionally with surface active agents(s), preferably anionic and/or nonionic emulsifying or dispersing agent(s). The invention further relates to the above compounds of the general formula (I) as well as to a process for the preparation thereof. The compounds according to the invention possess an outstanding herbicidal effect (over 90%) and advantageous selectivity threshold values against cultivated plants.

Novel herbicide composition

A herbicide composition, which comprises (S)-1'-methoxycarbonylethyl 2-bromo-5-(2-chloro-4-trifluoromethylphenoxy) benzoate or (S)-1'-ethoxycarbonylethyl 2-bromo-5-(2-chloro-4-trifluoromethylphenoxy)benzoate as active ingredient in an amount of 0.01 to 95.0% by weight together with one or more solid and/or liquid carriers, preferably grists of native or synthetic materials; and/or with inert solvents, preferably xylenes and/or cyclohexanone; and optionally with surface active agents, preferably anionic and/or nonionic emulsifying or dispersing agents.

Herbicide composition

The invention relates to new aryloxy phenoxy acyl malonates of the Formula I ##STR1## a process for the preparation thereof and herbicidal compositions comprising the same. In the Formula I
