Why are some pesticides restricted-use?

• A. They are too expensive
• B. They have too short shelf life
• C. They pose human toxicity, environmental harm, and groundwater contamination
• D. They are only for non-agricultural sites

Answer: (C)

Restricted-use status is tied to risk to people and the environment. These pesticides have the potential to cause serious harm if misused, including toxic effects to humans, harm to non-target wildlife, and the possibility of contaminating groundwater or surface water if they drift or are applied improperly. Because of that, their sale and use are restricted to certified applicators who follow strict label directions, wear protective gear, and implement safeguards like drift reduction and buffer zones. The other options miss the point: cost or shelf life don’t determine restricted-use status, and restricted-use isn’t defined by site type but by the level of risk involved.
