PURPOSE:An aggregation inhibitor, consisting essentially of a sulfonate of an alkyl diphenyl ether, capable of preventing aggregation in mixing and formulating paraquat with a water-insoluble biocide without reduction in controlling effect nor occurrence of phytotoxicity, etc. CONSTITUTION:An aggregation inhibitor consisting essentially of a sulfonate of an alkyl diphenyl ether expressed by formula I [R is 1-22C alkyl or alkenyl; M is alkali (earth) metal, NH4 or substituted ammonium expressed by formula II(R<1> and R<2> are H or 1-4C alkyl; R<3> is benzyl, phenyl, cyclohexyl, etc.)] is added to a mixed pharmaceutical of paraquat or diguat which is a foliar contact type extermination controlling agent with a water-insoluble biocide to form a safe complex salt and prevent the aggregation of the above-mentioned biocide without deteriorating water-solubility of the paraquat. EFFECT:Occurrence of aggregates in formulating a mixed biocide or using by diolution and mixing can be prevented, and trouble in application work, etc. can be eliminated due to reduction in controlling effect.
