Abstract
The present invention provides a polymorph of a benzamide compound and a preparation method and applications thereof. The shown benzamide compound is 3-Bromo-N-[2,4-dichloro-6-[(methylamino)carbonyl]phenyl]-1-(3,5-dichloro-2-pyridinyl)-1H-pyrazole-5-carboxamide. The application of the polymorph of the compound in the preparation of the formulation exhibits excellent effect. The advantages of the polymorph A in aspects such as chemical stability, filterability, solubility, hygroscopicity, melting point, solid density and flowability can have a significant impact on the developments of the production method and a formulation and on the quality and efficacy of a plant treating agent.
