Method for preparing emulsifiable solid agrochemical composition containing inorganic salt

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 minimise 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.
