Certain new ar or ar' (alkylthio) benzoyl chloride phenylhydrazones have been found to be anthelmintics and active against arthropod pests. The benzoyl ring and the phenylhydrazone ring can be otherwise substituted with, for example, halogen atoms, nitro groups, .alpha.-fluoroalkyl groups, other alkylthio groups, and alkyl groups. The new compounds are prepared by reacting an ar or ar' (alkylthio) benzoic acid 2-phenylhydrazide with phosphorus pentachloride to obtain an ar or ar' (alkylthio) benzoyl chloride (dichlorophosphinyl)phenylhydrazone that is reacted with phenol to produce the desired ar or ar' (alkylthio) benzoyl chloride phenylhydrazones. Certain of the compounds can be prepared by direct halogenation of (alkylthio)benzaldehyde phenylhydrazone or an (alkylthio)benzoyl chloride phenylhydrazone. Methods of anti-arthropodal use and novel formulations for use are also described.
