FLUMIOXAZIN is a benzoxazinones-type herbicide used on soybeans, peanuts, orchard fruits and other crop. It is a diphenyl ether group G herbicide that functioning through inhibiting the protoorphyrinogen oxidase. As a light-dependent peroxidising herbicide (LDPH), it takes effect by blocking heme and chlorophyll biosynthesis resulting in the accumulation of phototoxic porphyrins, leading to the membrane damage and further killing the weeds.
