Hexazinone acts on which botanical process?

• A. Cell membrane disruption
• B. Photosynthesis
• C. Amino acid synthesis
• D. Cellulose biosynthesis

Answer: (B)

Hexazinone is a systemic herbicide that primarily affects the photosynthesis process within plants. It works by inhibiting the electron transport chain in photosystem II, which is crucial for the light-dependent reactions of photosynthesis. By blocking this key process, hexazinone effectively disrupts the plant's ability to convert light energy into chemical energy, leading to reduced energy production and ultimately causing plant death. While other processes, such as cell membrane disruption, amino acid synthesis, and cellulose biosynthesis, are vital to plant health and function, hexazinone’s specific action targets photosynthesis, making it an effective herbicide in controlling unwanted vegetation in right-of-way settings. Understanding this mechanism is essential for pest control professionals who utilize hexazinone as part of their integrated pest management strategies.
