What is a correct statement concerning Restricted Use Pesticides?

Restricted Use Pesticides (RUPs) are designated for specific applications due to their potential hazards to human health and the environment. Because of their associated risks, RUPs can only be applied by individuals who have received proper training and certification, ensuring that they are knowledgeable about safe handling, application techniques, and regulatory compliance. This is why stating that RUPs can only be used by a certified applicator is the correct position.

The other options do not reflect the nature of RUPs appropriately. While it is possible that some RUPs could be more expensive, this is not a defining characteristic of all RUPs. Additionally, these pesticides are not restricted to use solely on animals or humans, nor are they limited to applications against insects, as they may target a variety of pests including weeds and diseases.
