Provided are an agrochemical composition containing pyribencarb which has good blendability with an agrochemical composition containing etofenprox, and a method for spraying the composition. The agrochemical composition which contains pyribencarb (A) and a surfactant (B), characterized in that, as the surfactant (B), a lignin sulfonic acid salt having purity of 85% by mass or more, wherein the content of reducing sugars is less than 5% by mass and the content of sugar sulfonic acids is less than 6% by mass (B1), and a monoalkylarylsulfonic acid salt formalin condensate and/or a polycarboxylic acid salt having mass average molecular weight of 5,000 to 50,000 (B2) are exclusively included; and the method for spraying the composition.

Agrochemical composition and dispersal method therefor

Provided are an agrochemical composition containing pyribencarb which has good blendability with an agrochemical composition containing etofenprox, and a method for spraying the composition. The agrochemical composition which contains pyribencarb (A) and a surfactant (B), characterized in that as the surfactant (B), a lignin sulfonic acid salt having purity of 85% by mass or more, wherein the content of reducing sugars is less than 5% by mass and the content of sugar sulfonic acids is less than 6% by mass (B1), and a monoalkylarylsulfonic acid salt formalin condensate and/or a polycarboxylic acid salt having mass average molecular weight of 5,000 to 50,000 (B2) are exclusively included; and the method for spraying the composition.

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 spraying in an amount of 31 times or less the total amount of the composition on mass basis.
