PROBLEM TO BE SOLVED: To obtain an agrochemical granule capable of reducing phytotoxicity without reducing the efficiency of agrochemicals, excellent in stability, capable of being produced by a low cost production method of kneading and granulating, suitable for mass production and exhibiting excellent sustained release properties to a nereistoxin derivative by using an inorganic acid and a solid carrier having absorption ability, especially an acid clay. SOLUTION: This agrochemical granule contains (A) 5-30 wt.% nereistoxin derivative or a salt thereof (preferably cartap or a salt thereof) based on the whole preparation, (B) an inorganic acid and (C) an acid clay. Preferably, the granule contains the component C in an amount of >=7 times as much as that of the component A expressed in terms of weight, and further contains (D) a guanidine derivative represented by the formula [R1 is a (substituted) homocyclic or heterocyclic group; n is 0 or 1; R2 is H or a (substituted) hydrocarbon; R3 is a primary, secondary or tertiary amino; X is an electron attracting group], especially 1-(2-chloro-5-thiazolylmethyl)-3-methyl-2-nitroguanidine or a salt thereof.
