What type of individual is not permitted to apply pesticides without supervision?

The option that indicates individuals not permitted to apply pesticides without supervision is focused on uncertified individuals. These are individuals who have not completed the necessary training and certification required by state regulations to handle and apply pesticides safely and effectively.

Uncertified individuals lack the knowledge of pesticide safety, proper application techniques, legal requirements, and the environmental impact of their work. Because of their lack of training, they must be supervised when applying pesticides to ensure compliance with safety standards and to minimize risk to public health and the environment.

In contrast, registered users and state-certified applicators have demonstrated their competency in handling pesticides and are permitted to apply them under certain conditions without the need for supervision. Commercial applicators, who are usually state-certified and knowledgeable about pesticide application, are also allowed to operate independently according to their certification. This context reinforces the importance of certification in ensuring safe practices in pesticide application.
