Disclosed is a stabilized liquid agrochemical composition which comprises flowable nonaqueous dispersion concentrates comprising a continuous substantially water-miscible liquid phase, a dispersed water-immiscible liquid phase, and a colloidal solid. The dispersed phase comprises at least one water-sensitive agrochemically active ingredient and the colloidal solid is disposed at the interface between the dispersed phase and the continuous phase. The compositions of the invention can be used directly or with dilution to combat pests or as plant growth regulators. An example of the colloidal solid is an alpha-cyclodextin/ 1-methyl cycopropene complex.
