2001 - "Synthesis of Benzfendiazone" by Saroj Sehgel, George Theodoridis (FMC Corporation). Ref: Trip Report: The 30th Northeast Regional Meeting of the American Chemical Society Durham, New Hampshire June 24-27, 2001.
2000: Abstract: Benzfendizone belongs to the 2-[(4-heterocyclic-phenoxymethyl)-phenoxy]alkanoate class of herbicides which are potent inhibitors of the plant enzyme protoporphyrinogen oxidase (Protox). Benzfendizone, when applied postemergence, provides control of a number of key grass and broadleaf weeds in orchards and no-till crop situations. Benzfendizone can also be used as a potato desiccant and cotton defoliant. Crops such as soyabean and corn showed no injury when planted 2–3 days following postemergence application of benzfendizone.
