Which COMAR title contains regulations on pesticides?

The correct title that contains regulations on pesticides is Title 15. Title 15 of the Code of Maryland Regulations specifically addresses the regulation of pesticides, including their registration, licensing of pesticide applicators, and the labeling and use of pesticides in the state. This title establishes the framework for the safe and responsible use of pesticides, ensuring environmental protection and public health.

The other titles mentioned focus on different areas: Title 10 primarily deals with health and mental hygiene regulations, Title 20 pertains to the environment but does not focus specifically on pesticides, and Title 25 covers various administrative functions that do not include pesticide regulations. Therefore, Title 15 is the appropriate resource for understanding the regulatory requirements regarding pesticides in Maryland.
