Which of the following must be done before applying restricted use pesticides?

Before applying restricted use pesticides, obtaining an applicator license is essential because this license ensures that the individual has completed the necessary training and understands the safe and effective use of these pesticides. The licensing process typically includes education on the potential hazards of pesticides, proper application techniques, and legal responsibilities, which are crucial for the protection of public health and the environment.

While notifying local authorities or filling out application forms may be required in certain situations or jurisdictions, these actions do not directly pertain to the prerequisites for handling restricted use pesticides. Completing a training program is also necessary, but obtaining the applicator license serves as the formal recognition of that training, ensuring that the individual is qualified to apply these potentially hazardous substances safely.
