PROBLEM TO BE SOLVED: To provide an agrochemical formulation of new type which allows the controlled release of an agrochemical active compound. SOLUTION: The method for producing a coated powdery agrochemical comprises (1) a process of stirring/mixing a powdery agrochemical with a silicone oil, (2) a process of stirring/mixing the obtained mixture with a first liquid raw material (x) being a raw material for a thermosetting resin (x), (3) a process of mixing the obtained mixture with a second liquid raw material (x) being a raw material for the thermosetting resin (x), (4) a process of reacting the first liquid raw material (x) with the second liquid raw material (x) with stirring/mixing to give an inner core in which the powdery agrochemical is solidified with the thermosetting resin (x), and (5) a process of successively or simultaneously adding a first liquid raw material (y) and a second liquid raw material (y) being raw materials for a thermosetting resin (y) to the obtained inner core, reacting the first liquid raw material (y) with the second liquid raw material (y) while stirring/mixing and coating the inner core with the thermosetting resin (y).
