摘要

A pesticidal aqueous suspension concentrate containing as an active ingredient a 3-substituted pyrazole derivative represented by the general formula (I): <IMG> (I) (wherein the substituents are as defined in the description of the specification) in which the 50% particle size and 90% particle size in cumulative particle size distribution of particles of the active ingredient are less than 1 .mu.m and less than 2 .mu.m, respectively, and which is harmless to useful crops and is equal to an emulsifiable concentrate in herbicidal effect; and a process for producing said pesticidal aqueous suspension concentrate.
