The present invention provides a method for producing agrochemical granules, which contain an agrochemical active ingredient, one or more kinds of hydrophobic substances, and a substance capable of absorbing oil, with stable quality. The method for producing agrochemical granules of the present invention includes (i) a step of obtaining a mixture by mixing an agrochemical active ingredient, one or more kinds of hydrophobic substances, and a substance capable of absorbing oil together, (ii) a step of obtaining a kneaded material by loading the obtained mixture into a kneading device, kneading the mixture at a heating temperature equal to or higher than the highest melting point of the hydrophobic substances, and then causing the kneaded material to be discharged from the kneading device at a temperature equal to or lower than the highest melting point of the hydrophobic substances, and (iii) a step of granulating the obtained kneaded material by an extrusion molding method.
