摘要

Crystalline polymorph, mixture polymorphic amorphous compound, process for the preparation of a polymorphic crystalline powder, process for the preparation of a polymorphic crystalline mixture, process for the preparation of (E) - 2 - (2 - [6 - (2 - cianofenoxi) pirimidin - 4 inncn] phenyl} - 3 - metoxiacrilato the Morpho, composition to combat fungi.Method for combating fungi on a plant and method for protecting crops from fungi. The present invention relates to new polymorphic forms and amorphous crystalline compound (E) - 2 - (2 - [6 - (2 - cianofenoxi) pirimidin - 4 inncn] phenyl} - 3 - metoxiacrilato (azoxystrobin).The infrared spectra, Raman, X-ray diffraction pattern and termograma post differential calorimetry exploratory of the two polymorphic forms "a" and "B" are provided. In addition, the present invention also provides methods for preparing the new polymorphic forms "a" and "B", as well as processes to produce mixtures of polymorphs, and to a process for preparing azoxystrobin amorphous.Moreover, the present invention provides antifungal compositions comprising crystalline polymorphs of new "a" and "B" or azoxystrobin amorphous, useful to control and combat the growth of fungi in agricultural and horticultural crops in cuitivos and highlands, and the methods to a Izar as agents for combating fungi in pesticidads cuitivos agricultural and horticultural.
