    Abstract: Disclosed is a process for preparing solid fipronil comprising at least 85 percent by weight of the crystalline modification I of fipronil being present in the monoclinic system having the centrosymmetric space group C2/c comprising the steps of: step i) preparing a solution of a solid form of fipronil being different from the crystalline modification I in a solvent S comprising at least one acetonitrile, dimethylsulfoxide, or at least one benzene derivative; step ii) effecting crystallization of fipronil; and step iii) isolating the resulting precipitate wherein, in case the solvent S is pure acetonitrile, the crystallization step ii) is conducted at temperatures below 40 degrees Celsius and in case the solvent S is pure dimethylsulfoxide, the crystallization step ii) is conducted at temperatures below 80 degrees Celsius.

    Abstract: Crystalline modification IV of pyraclostrobin (A) exhibits at least three reflexes in an X-ray powder diffractogram at 25[deg]C, where the reflections (d) are 6.02 +- 0.01 Å, 4.78 +- 0.01 Å, 4.01 +- 0.01 Å, 3.55 +- 0.01 Å and 3.01 +- 0.01 Å. Independent claims are included for: (1) the preparation of (A); (2) crystalline modification II of pyroclostobin (A1) exhibiting at least four reflexes in a X-ray powder diffractogram at 25[deg]C, where the reflections (d) are 5.93 +- 0.01 Å, 5.82 +- 0.01 Å, 4.89 +- 0.01 Å, 4.78 +- 0.01 Å, 4.71 +- 0.01 Å, 3.97 +- 0.01 Å, 3.89 +- 0.01 Å, 3.77 +- 0.01 Å, 3.75 +- 0.01 Å, 3.57 +- 0.01 Å and 3.43 +- 0.01 Å; (3) the preparation of (A1); and (4) a plant protection agent, which comprises pyraclostrobin in the form of modification IV or in the form of modification II and carrier materials and/or additives. ACTIVITY : Fungicide. MECHANISM OF ACTION : None given.
