Flumioxazin is a synthetic herbicide used for control of broadleaf weeds in agricultural areas. Valent U.S.A. Corporation, a division of Sumitomo Chemical, developed flumioxazin, which was approved by the U.S. EPA in 2001 for use on soybean and peanut crops. Flumioxazin has gained popularity due to pesticide resistance toward earlier active ingredients.
Flumioxazin is also used to control aquatic plants such as filamentous algae. In granular form, it is used to control of submerged plants, and as a direct foliar application it is used to control emergent and floating-leaf plants.
Flumioxazin is an inhibitor of the enzyme protoporphyrinogen oxidase which then interferes with the plant's chlorophyll production.
Flumioxazin's HRAC classification is (Australia), (global), or (numeric).
The production of flumioxazin involves the use of 2,4-difluoronitrobenzene as a crucial raw material.
