The U.S. Environmental Protection Agency may classify a pesticide as a restricted use pesticide if it __________.

The classification of a pesticide as a restricted use pesticide is a critical regulatory measure that aims to ensure the safety of applicators and the environment. When the U.S. Environmental Protection Agency (EPA) determines that a pesticide poses significant risks, particularly to those applying it, it may impose restrictions on its use.

In the case of dermal hazards, if a pesticide is found to present a significant risk through skin contact, it can be classified as a restricted use pesticide. This classification is warranted because dermal exposure can lead to serious health effects, including acute poisoning or chronic health issues, necessitating that only certified applicators handle such products to minimize risks.

Other options present factors related to pesticide efficacy, residues, and breakdown time, but they do not directly relate to immediate health risks to the applicators. The focus of the EPA’s assessment for restricted use revolves around human health risks and environmental impact, making the dermal hazard the most pertinent criterion in this scenario.
