Bifenox

Bifenox is an herbicide of the diphenyl ether class.
Bifenox is a protoporphyrinogen oxidase inhibitor and acts on the young parts, leaves, and partially on the roots of weeds and grasses. This leads to a release of peroxides that destroy the cell membranes of the weed plants and lead to tissue death. Bifenox also inhibits photosynthesis. The effect is enhanced by high light intensity and metabolic activity.
