A formulation e.g., a pesticidal formulation in the form of a dispersion comprising a continuous aqueous phase, and a discontinuous phase comprising a non-aqueous material capable of transport through the aqueous phase to cause Ostwald ripening of the dispersion, wherein there is contained within the discontinuous phase a pesticidal material, which may or may not be the said non-aqueous material, wherein the discontinuous phase comprises a stabiliser in an amont sufficien t to depress migration of the non-aqueous material through the aqueous phase, and thereby diminish or prevent Ostwald ripening of the dispersion, characterised in that the stabiliser has a molecular weight of not mon than 10,000, and is soluble in the discontinuous phase, bu t insoluble in and not transportable through the aqueous phase. The production of the formulation can be carried out in a metered in-line mixing plant, since the thermodynamics of the mining process is such that the particle size tends to a predictable value.
