The present invention relates to a suspoemulsion comprising the following ingredients (1), (2), (3), (4), (5), and (6): an ingredient (1): low water-soluble liquid pesticidal ingredient, an ingredient (2): low water-soluble pesticidal active ingredient which is solid at normal temperature, an ingredient (3): polyoxyalkylene block copolymer, an ingredient (4): phosphate ester salt and/or sulfate ester salt of polyoxyethylene aryl phenyl ether, an ingredient (5): ligninsulfonic acid salt, and an ingredient (6): water. The suspoemulsion of the present invention is a formulation having excellent storage stability, which suppresses the particle growth of dispersoids of an ingredient (1) and an ingredient (2) during storage at high temperature and low temperature, and causes neither aggregation nor separation of dispersoids, nor formation of a hard cake, nor a change in appearance.
