A pesticide is defined as what?

• A. A nutrient used by plants
• B. Any substance used to directly control pest populations or reduce pest damage
• C. A fertilizer
• D. A plant growth regulator

Answer: (B)

Pesticides are substances used to prevent, destroy, or reduce pests and the damage pests cause. The statement that describes any substance used to directly control pest populations or reduce pest damage matches that purpose, covering tools like insecticides, herbicides, fungicides, and even some biological products. Nutrients or fertilizers are meant to feed plants and help them grow, not to manage pest pressures, and a plant growth regulator adjusts how a plant grows rather than targeting pests. So the best answer is the one that centers on directly controlling pests or reducing the damage they cause, reflecting the true function of pesticides.
