PROBLEM TO BE SOLVED: To provide a microcapsule for plant disease control.SOLUTION: A microcapsule that is a microcapsule in which a core material containing a fungicidal active ingredient is enclosed within a shell material, wherein the microcapsule satisfies the following conditions (1) and (2) is a formulation that withstands physical impacts, drying and diluting, and suitable for seed treatment using a stirring type machine, and the durability of control of diseases of crops and the safety for the crops can be improved more efficiently by the microcapsule. The condition (1): D/T≤230, the condition (2): (D-D)/D≤2.5, wherein in the formulae of conditions (1) and (2), T represents the shell thickness (μm) of the microcapsule, Drepresents the 10% cumulative volume particle diameter (μm) of the microcapsule, Drepresents the 50% cumulative volume particle diameter (μm) of the microcapsule, and Drepresents the 90% cumulative volume particle diameter (μm) of the microcapsule. |
