Which of the following is a common type of FAS inhibitor?

• A. 2,4-D
• B. Horizon
• C. Tordon
• D. Thiocarbamate

Answer: (B)

Horizon is a common type of FAS (fatty acid synthesis) inhibitor. It functions by disrupting the process of fatty acid synthesis in plants, which is essential for their growth and development. This mechanism targets specific enzymes involved in the metabolic pathway that leads to the formation of fatty acids, ultimately affecting the overall health and vitality of the plant. FAS inhibitors like Horizon are effective because they exploit the differences between plant and animal metabolism. Since plants rely heavily on fatty acids for cellular structure and energy, inhibiting their synthesis can lead to significant physiological stress and negatively impact growth, making FAS inhibitors a valuable tool for controlling certain unwanted plants and weeds. In contrast, the other options—2,4-D, Tordon, and Thiocarbamate—are categorized differently and act via other modes of action. Understanding the specific action of Horizon helps clarify its role in weed management and the importance of target-specific herbicide mechanisms in agricultural practices.
