    Abstract: PROBLEM TO BE SOLVED: To provide a novel crystalline transformation of fipronyl, and a method for producing said crystalline transformation, and also a composition for combating pests and parasites.SOLUTION: Use of a novel crystalline transformation IV of fipronyl of formula I below that exists in a triclinic crystalline system having center symmetric space group P-1. Said fipronyl is dissolved into acetone and crystallized to obtain crystalline transformation IV, and which is used, as it is (crystalline transformation IV), as a composition for controlling pests. High purity fipronyl of said crystalline transformation IV is a raw material for converting to crystalline transformation IV by further tempering the crystalline transformation IV at 90 to 100°C, or to crystalline transformation V by tempering at 100 to 130°C.

    Abstract: PROBLEM TO BE SOLVED: To provide a fipronyl crystal allowing easy filtration and drying with less dust in a production procedure and a composition which is blended with the crystal, has formulation stability and is for insecticidal and parasiticidal mixtures.SOLUTION: A solid fipronyl is present as a monoclinic system having a center-symmetry space group C2/c, shows a specific reflection in an X-ray powder diffraction diagram recorded at 25°C by using Cu-Kα radiation rays and contains at least 85 wt.% of a crystal transformation I of fipronyl. A method of producing the crystal transformation I comprises dissolving a solid fipronyl different from the crystal transformation I in a solvent selected from one or more of alcohols, acetonitrile(AN), dimethylsulfoxide(DMSO), one or more of benzene derivatives, etc. and crystallizing from the resultant solution. When the solvent is AN, crystallization is carried out at 40°C or lower. When the solvent is DMSO, crystallization is carried out at 80°C or lower.
