WebbProtoporphyrinogen oxidase-inhibiting herbicides. 1991 • Tim Sherman. Several commercial and experimental herbicides such as p-nitrodiphenyl ethers, oxadiazoles, and cyclic imides inhibit protoporphyrinogen IX oxidase (Protox), the enzyme that converts protoporphyrinogen IX to protoporphyrin IX (Proto). WebbThe protoporphyrinogen oxidase (PPO) inhibitors are primarily contact-type, postemergence, broadleaf-weed herbicides, but a few have preemergence soil activity. The primary mechanism of action of these herbicides is inhibition of the PPO enzyme which ultimately leads to disruption of cell membranes. mahaffey construction sweetwater tx
