    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.

    Abstract: Disclosed is a crystalline modification IV of pyraclostrobin which, in an X-ray powder diffractogram at 25°C, shows at least three of the following reflexes: d = 6.02 ± 0.01 Å, d = 4.78 ± 0.01 Å, d = 4.01 ± 0.01 Å, d = 3.55 ± 0.01 Å and d = 3.01 ± 0.01 Å. Also disclosed is a process for preparing a crystalline modification IV of pyraclostrobin as defined above, which comprises: i) dissolving a pyraclostrobin form different from modification IV in an organic solvent or solvent mixture, where the organic solvent or solvent mixture comprises at least 70% by volume of at least one fully water-miscible organic solvent L1 (such as methanol, ethanol, acetone or butanone) and if appropriate up to 30% by volume of water; and ii) effecting crystallization of pyraclostrobin over a period of at least 10 h and/or in the presence of seed crystals of modification IV.
