Which one of the following pesticides can be absorbed by the plant and translocated within the plant?

A systemic pesticide is designed to be absorbed by the plant, allowing it to move throughout the plant’s tissues. This ability is crucial for targeting pests that may be protected from contact pesticides, which only affect the exterior of the plant. Because systemic pesticides circulate within the plant, they can control pests that feed on various parts of the plant, including the roots, stems, and leaves. This makes them particularly effective for managing infestations that are not easily reached through surface applications.

In contrast, contact pesticides only act on the surfaces they are applied to and do not penetrate the plant tissue. Absorptive pesticides is not a standard classification in pest management; instead, the term systemic correctly describes the ability to be absorbed and translocated. Lastly, volatile pesticides are characterized by their tendency to evaporate quickly, which affects their application and persistence rather than their absorption by the plant. Thus, the definition and function of a systemic pesticide make it the correct choice in this context.
