Diflufenican Usage And Synthesis

Description	The diflufenican is a selective contact and residual herbicide that can be applied pre-emergence and post-emergence. It can be absorbed through the shoots of the germinating seeding with limited translocation. Its mode of mechanism is via a bleaching action through inhibiting the carotenoid biosynthesis process, further blocking photosynthesis process and causing plant death. It is used for the treatment of some broad leaved weeds such as Stellaria media (Chickweed), Veronica Spp (Speedwell), Viola spp, Geranium spp (Cranesbill) and Laminum spp (Dead nettles). It has been approved for use on barley, durum wheat, rye, triticale and wheat. It can be used in combination with isoproturon or other cereal herbicides.
