The correct classification for a person who applies pesticides to lawns as part of their business aligns with the term "Professional Applicator." This designation typically refers to individuals who are engaged in pesticide application as a profession rather than for personal use or in a research capacity.

Professional Applicators are generally required to adhere to specific regulations and standards set forth by state and federal agencies, which include obtaining proper licensing and completing necessary training to ensure safety and compliance with environmental regulations. This classification emphasizes the professional nature of their work, as it often involves significant knowledge of pest management practices, pesticide selection, application techniques, and safety measures.

While the other classifications—Private, Commercial, and Limited Applicators—may apply in different contexts, they do not capture the professional aspect of the individual's role in the pesticide application business in the same way that "Professional Applicator" does. Each of these terms has distinct definitions based on how and where pesticides are used.
