Tris(aryl)alkyl phosphonium halides and pesticidal compositions thereof

摘要

Tri(phenyl)alkyl phosphonium halides wherein the phenyl groups contain a long chain or sterically hindered alkyl group are novel and exhibit efficacious levels of fungicidal and bacteriocidal activity. The presence of the alkyl substituent eliminates or significantly reduces the phytotoxicity that characterizes the corresponding unsubstituted phosphonium compounds.
