| Questions And Answer | Back Directory | [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.

| Hazard Information | Back Directory | [Uses]
Herbicide. | [Uses]
Pre and post emergence foliar absorbed herbicide for winter weed control in cereal crops; carotenoid biosynthesis inhibitor. | [Definition]
ChEBI: A pyridinecarboxamide that is pyridine-3-carboxamide substituted by a 2,4-difluorophenyl group at the carbamoyl nitrogen and a 3-(trifluoromethyl)phenoxy group at position 2. | [Production Methods]
Diflufenican is commercially produced through a multi-step chemical synthesis involving fluorinated aromatic compounds and nicotinanilide intermediates. The process typically starts with the construction of a difluorophenyl ring, which is then coupled with a nicotinamide derivative via selective substitution and condensation reactions. | [Agricultural Uses]
Herbicide: Pre-and post-emergence foliar absorbed herbicide
for winter weed control in cereal crops; carotenoid biosynthesis inhibitor. Used on crops such as apples, apricot,
barley, beans (dry), broad beans, cherry, grapefruit, lemon,
lime, loquat, natsudaidai (whole), nectarine, orange,
peach, pear, peas, persimon, plum,quince, rye, soybeans,
unshu orange and wheat. Not currently registered in the
U.S. Approved for use in EU countries. | [Trade name]
