The present invention relates to a mixed agrochemical emulsion composition comprising: an organic phosphorous pesticide represented by formula (I)(wherein, R1 represents a C1-4 linear or branched alkyl group R2 represents a C1-4 linear or branched alkyl group R3 represents a nitrogenated heterocyclic group which may have a substituent or a group —OR4 (wherein R4 represents a nitrogenated heterocyclic group which may have a substituent and X and Y each independently represent an oxygen atom or a sulfur atom, wherein Y is a sulfur atom when X is an oxygen atom, and Y is an oxygen atom when X is a sulfur atom) chloropicrin and a nonionic surfactant. The composition has excellent storage stability and excellent emulsifying properties in water and can be sprayed and applied conveniently by diluting the composition with water, in spite of a fact that both chloropicrin and the organic phosphorous pesticide, which are effective for the control of pests, are contained.
