    Abstract: The invention relates to a method for the selective crystallization of poly- or monomethylol alkanoic acids of the general formula (I), wherein R is the same or different and represents a methylol group or a substituted or unsubstituted aliphatic hydrocarbon, with an essentially monomodal particle size distribution. This particle size distribution is achieved by crystallization in a temperature interval of from 85 DEG C to 50 DEG C observing a cooling rate of

    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.
