Which of the following statements is true regarding pesticide applicators?

The statement regarding pesticide applicators that is true is that they must take exams for certification. This requirement is crucial because certification ensures that applicators possess the necessary knowledge and skills to apply pesticides safely and effectively. The testing process evaluates their understanding of pesticide use, safety protocols, environmental impact, and legal responsibilities under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) as well as any state-specific regulations.

Certification through examination not only helps protect the applicators themselves but also safeguards the public and the environment from potential hazards associated with improper pesticide application. It is a systematic approach to ensure that professionals in the field are competent and informed about the substances they are handling, the techniques they utilize, and the risks involved.

Regarding the other options, it is important to note that all pesticide applicators are indeed required to comply with both federal and state regulations, which involve certification processes and exams. Furthermore, applicators cannot operate without any restrictions due to the stringent guidelines that govern pesticide applications to prevent environmental contamination and health risks. Lastly, pesticide applicators are regulated by both federal laws like FIFRA and state laws, making option D incomplete, since it implies that state laws are the only regulations in place.
