The invention discloses a microcapsule formulation composition. The microcapsule formulation composition is prepared from the following components: a suspension liquid containing triclopyricarb as inner water phase, a suspension liquid containing fluxapyroxad as outer water phase, oil phase containing a degradable polymer organic solvent material, an emulsifier, a thickener and water. According tothe microcapsule formulation composition, on the one hand, the unexpected technical effect is achieved after two components with different action mechanism are compounded, and it is found that the microcapsule formulation composition has significant synergistic effect on a tomato gray mold. According to the technical scheme, the drug loading capacity is improved by forming microcapsules, the effectiveness of drugs is ensured, and the drug release speed can further be controlled.
