What is a key restriction on an applicator working alone?

• A. They may not apply pesticides on their own
• B. They have to file reports before working
• C. They can only apply in residential areas
• D. They must have special training

Answer: (A)

The key restriction on an applicator working alone is that they may not apply pesticides on their own. This regulation is designed to ensure safety and proper handling of pesticides, as the application can pose significant risks to the applicator and the environment without adequate oversight or support. Having a second person present can help mitigate these risks by ensuring that there is someone to assist in case of an emergency, manage equipment, and follow appropriate safety protocols.

The other options address related topics but do not directly encapsulate the main regulatory concern about solitary pesticide application. Filing reports, geographic restrictions, and special training are important aspects of pesticide application and regulation but are not specific to the requirement for having support while applying pesticides.
