Diflufenican APPLICATIONS
Biochemistry Blocks carotenoid biosynthesis, by inhibition of phytoene desaturase. Mode of action Selective contact and residual herbicide, absorbed principally by the shoots of germinating seedlings, with limited translocation. Uses Applied at 125-250 g/ha pre- or early post-emergence in autumn-sown wheat and barley, to control grass and broad-leaved weeds, particularly Galium, Veronica and Viola spp. Normally used in combination with isoproturon or other cereal herbicides. Phytotoxicity Any slight phytotoxicity is in the form of small transient patches on basal leaves, with no adverse effect on crop development. Formulation types SC; WP.

Diflufenican ANALYSIS
Methods have been developed to determine residues in plants and soil (J. Agric. Food Chem. 1991, 39(5), 968-76).
