Which term describes herbicides that kill plants by being absorbed and moving throughout the plant?

• A. Translocated Herbicides
• B. Plant Growth Regulator
• C. Systemics
• D. Fumigants

Answer: (A)

Herbicides that kill plants by being absorbed and moving throughout the plant are described by the term translocated herbicides. After uptake, these chemicals travel through the plant’s vascular system to reach meristematic and growth tissues, where they disrupt essential processes and cause whole-plant death. This internal movement is the defining feature, which is captured most precisely by the term translocated herbicides. While systemic herbicides convey the idea of movement within the plant, the wording here centers on the transport aspect itself. Plant Growth Regulators affect growth control rather than relying on internal transport to kill, fumigants are gases used for soil or space treatment, and Systemics is a broader label for systemic behavior but doesn’t highlight the transport aspect as clearly as translocated herbicides.
