Emulsion SNB (manufactured by Kao Corporation, a surfactant that is a condensate of sodium arylsulfonate and formalin) was used in the same manner as in Preparation Example 1 except that 80 g was used, but when emulsifying the prochloraz solution in the slurry. In addition, the viscosity was increased and huge aggregated particles were formed, and a uniform pesticide composition could not be obtained. Reference Formulation Example 4 In Formulation Example 1, S was used instead of 80 g of Reax85A.
All were the same as in Preparation Example 1 except that 80 g of oprophor FL (a surfactant that is an ethylene oxide adduct of tristyrylphenol phosphate manufactured by Rhone Poulenc Co., Ltd.) was used, but when emulsifying the prochloraz solution in a slurry. Increased viscosity and generation of huge aggregated particles were observed, and a uniform pesticide composition could not be obtained.

Reference Formulation Example 6 Formulation Example 1 is the same as Formulation Example 1, except that 80 g of Newpol PE-108 (Sanyo Chemical Co., Ltd. nonionic surfactant, polyoxyethylene polyoxypropylene block copolymer) was used instead of 20 g of Reax85A. 1
The same procedure was followed, but when the prochloraz solution was emulsified in the slurry, the viscosity was increased, and huge agglomerated particles were formed, so that a uniform pesticide composition could not be obtained.

When emulsified in a slurry, the viscosity was increased, and formation of huge aggregated particles was observed, and a uniform pesticide composition could not be obtained. Reference formulation example 8 In Formulation example 1, G was replaced with 80 g of Reax85A.
