PURPOSE: To provide a stable aqueous emulsified herbicide suspension composition containing a herbicide exhibiting liquid state and a herbicide exhibiting solid state at normal temperature and scarcely soluble in water.
CONSTITUTION: A liquid herbicide and a solid herbicide scarcely soluble in water are formulated in the form of a herbicide formulation with a wet ball-mill crusher using a specific surfactant (calcium dodecylbenzenesulfonate, ethoxylated styryl phenyl ether and ethoxylated castor oil) and a thixotropic agent (e.g. quaternary ammonium bentonite). The suspo-emulsion produced by this process has physical and chemical stability even after the storage for a long period at low temperature or high temperature in spite of its low viscosity.
