Provided are an aqueous suspension agrochemical composition of pyribencarb suitable for aerial spraying and a method for spraying the composition, wherein storage stability is not impaired since particle growth over time is suppressed, and hard cake formation is suppressed even when a spray solution is prepared at a high concentration with a low dilution factor at the time of use. The present invention is an aqueous suspension agrochemical composition characterized by containing pyribencarb which is an agrochemically active component, a polyacrylic acid salt, a surfactant, a thickener, and water. The present invention is a method for aerial spraying of an aqueous suspension agrochemical composition, which comprises spraying a diluted solution onto agricultural land or non-agricultural land at an amount of 8 to 32 kg/ha from an aircraft equipped with an agricultural preparation spraying function, the diluted solution being prepared by diluting the aqueous suspension agrochemical composition in water for sprayi
