CAS No.: [ 113158-40-0 ]

Molecular Formula: C18H16ClNO5

Fenoxaprop-P-ethyl is the herbicidally active R-enantiomer of the racemic substance
fenoxaprop-ethyl. It is an aryloxyphenoxypropionate herbicide, used for postemergence
control of annual grass weeds, from the two-leaf stage up to full tillering,
in spring and winter wheat, spring and winter barley, rice, turf and various broadleaf
crops. The mode of action and reason for its selectivity is by inhibition of the Acetyl-
CoA-carboxylase in grasses, the enzyme catalyzing the first step in the de novo
synthesis of fatty acids. The depletion of fatty acids supply blocks the production of
phospholipids essential in the cell growth of sensitive plants. Incorporation of a
safener to improve the selectivity is required for uses in cereals and rice, as these
crops also belong to the family of grasses.

Biochemistry Fatty acid synthesis inhibition in grasses, by inhibition of acetyl CoA carboxylase (ACCase).

Mode of action
Fenoxaprop-P-ethyl is a selective herbicide with contact and systemic action, absorbed principally by the leaves, with translocation both acropetally and basipetally to the roots or rhizomes.

Post-emergence control of annual and perennial grass weeds in potatoes, beans, soya beans, beets, vegetables, peanuts, flax, oilseed rape, and cotton; and (when applied with the herbicide safener mefenpyr-diethyl) annual and perennial grass weeds and wild oats in wheat, rye, triticale and, depending on ratio, in some varieties of barley.

Non-phytotoxic to broad-leaved crops.

Formulation types EC; EW; SE.
