. Bentazon is a photosystem II (PSII) inhibiting herbicide. As a PSII inhibitor, it interferes with the electron transport chain and can cause significant oxidative stress in plants. Bentazon works by competitively binding to plastoquinone and thereby blocking electron flow from plastoquinone. Plastoquinone is responsible for passing the electrons to the cytochrome complex, which is responsible for pumping proteins into the thylakoid lumen. Discuss how this action of Bentazon can lead to plant death.
