Which statement is true about highly toxic pesticides?

The statement that highly toxic pesticides are not always the most hazardous pesticides is accurate because the classification of toxicity can vary significantly depending on various factors such as the route of exposure, the formulation of the pesticide, and the specific context in which it is used.

Highly toxic pesticides are designated based on specific toxicity criteria, but some pesticides may pose serious risks due to their chemical properties, environmental persistence, or potential for exposure. Thus, while a pesticide may be classified as having high toxicity, it doesn't automatically imply that it presents the greatest risk in all scenarios. Other considerations, such as the application method, exposure level, and the presence of non-target species or sensitive populations, also play a crucial role in determining overall hazard levels.

Pesticides classified as safe for household use typically undergo rigorous testing and are formulated to minimize risks to humans and pets, which may not align with the general perceptions of toxicity. Furthermore, certain pesticides can be used indoors, but that doesn't mean all highly toxic pesticides are advisable or legal for indoor use. Each pesticide requires careful consideration based on its characteristics and intended application.
