FIELD: agriculture.
SUBSTANCE: invention refers to agriculture. Polymorph of 4-(2-bromo-4-fluorophenyl)-N-(2-chloro-6-fluorophenyl)-1,3-dimethyl-1H-pyrazol-5-amine is proposed. To prepare the polymorph form B, a slurry is formed with a solvent of one or more solid forms 4-(2-bromo-4-fluorophenyl)-N-(2-chloro-6-fluorophenyl)-1,3-dimethyl-1H-pyrazole-5-amine, selected from the group of form A, amorphous forms and mixtures of any of the above, with form B and maintaining the slurry during the conversion of solid forms 4-(2-bromo-4-fluorophenyl)-N-(2-chloro-6-fluorophenyl)-1,3-dimethyl-1H-pyrazole-5-amine into polymorph B.
EFFECT: invention will increase the effectiveness of protecting plants and seeds from fungal infections.
