What does the dose‑response concept tell us about pesticide use?

• A. Dose doesn't affect risk
• B. Dose-response
• C. Color
• D. Random

Answer: (B)

Dose determines the effect: the dose-response concept says that how much pesticide you or the environment are exposed to influences the level of effect or risk. In practice, using more pesticide generally leads to greater pest control but also higher chances of adverse effects to people, non-target organisms, and the environment. This is why the goal is to use the smallest effective amount and follow label directions, calibrate equipment, and minimize exposure and drift. Color and randomness don’t describe how risk changes with exposure, so they don’t fit the idea of a dose–response relationship.
