Herbicides that move in a plant are termed?

• A. Localized (Contact)
• B. Nonselective
• C. Translocated (Systemic)
• D. Nonpersistent

Answer: (C)

Translocated (systemic) movement inside a plant is when the herbicide is absorbed and then transported to other tissues beyond the spray site, through the plant’s vascular system, so it can reach roots, growing points, or new leaves. This property lets a single application affect parts of the plant you didn’t directly contact, which is the defining feature of systemic herbicides. That’s why this term is the correct choice.

In contrast, localized (contact) herbicides stay where they are sprayed and don’t move throughout the plant, so they only affect the tissues they touch. Nonselective describes the range of plants the herbicide can affect, not how it moves inside the plant. Nonpersistent refers to how long the chemical remains active in the environment, not its internal movement.
