Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain an amorphous benzoylurea capable of remarkably improving the absorptivity from an alimentary canal when orally administered to a warm- blooded animal and a parasite controlling agent containing the amorphous benzoylurea as an active ingredient. SOLUTION: This amorphous benzoylurea is amorphous N-(2,6- difluorobenzoyl)-N'-[3,5-dichloro-4-(3-chloro-5-trifluoromthyl-2-pyrid yloxy) phenyl]urea. This parasite controlling agent contains the amorphous N-(2,6- difluorobenzoyl)-N'-[3,5-dichloro-4-(3-chloro-5-trifluoromthyl-2-pyrid yloxy) phenyl]urea as an active ingredient. The controlling agent is produced by removing a solvent from a solution prepared by dissolving the N-(2,6-difluorobenzoyl)- N'-[3,5-dichloro-4-(3-chloro-5-trifluoromthyl-2-pyridyloxy)phenyl]urea and a water- soluble high-molecular compound in the solvent.
