The present invention relates to a method for preparing an emulsifiable solid agrochemical composition which contains an inorganic salt and which can be used as an agrochemical emulsion. The preparation method according to the present invention has the advantage that, because there is no need for a step of heating and evaporating a solvent or water, it is possible to use a surfactant or active ingredient that has a low boiling point or breaks down drastically at a high temperature, and, due to the solid-phase form, it is possible to minimize the amount that sticks to a container as there is no need to use a special synthetic resin or glass bottle that entails high packaging costs. Also, a granular emulsifier (EG) or a powdery emulsifier (EP) produced by means of the method according to the present invention can be further diluted in water before use so as to form common emulsion (EC) emulsified particles (0.1 µm to 100 µm) to transparent microemulsion particles (0.001 µm to 1 µm or 1 nm to 1000 nm), and thus the emulsion size can be freely modified so as to maximise the activity of the agrochemical component in accordance with the characteristics of a crop or an insect pest.
