Why are certain pesticides classified as "restricted use" by the EPA?

Pesticides are classified as "restricted use" by the Environmental Protection Agency (EPA) primarily because they may cause unreasonable adverse effects to health or the environment. This classification is indicative of a higher level of risk associated with the pesticide, which could include potential harm to human health, wildlife, or the surrounding ecosystem.

To manage these risks effectively, restricted use pesticides can only be applied by certified applicators who have received specialized training and understand the appropriate usage, handling, and safety protocols. The regulations surrounding restricted use pesticides aim to minimize exposure and mitigate potential negative impacts, thereby protecting both public health and the environment.

In contrast, factors such as cost, labeling information, or the limitation of use to agricultural purposes do not directly correlate with why a pesticide is assigned restricted use status. The emphasis is on the potential dangers these products pose rather than their usability, marketing considerations, or specific application settings.
