The present invention relates to aqueous flowable concentrate compositions of a microencapsulated dinitroanline herbicide, in particular pendimethalin, which are flowable and have improved storage stability. The compositions contain: i. 50 to 400 g/l of a dinitroaniline herbicide in the form of microcapsules comprising a core material containing the dinitroaniline herbicide, in particular pendimethalin, and a polymeric wall material, the microcapsules being dispersed in an aqueous phase; ii. 100 to 500 g/l of a glyphosate salt which is dissolved in the aqueous phase and iii. at least one anionic surface-active substance.
