Maryland Code, Agriculture § 5-112

(a) The Secretary shall examine pesticides to determine whether they comply with the requirements of this subtitle. If it appears from the examination that a pesticide fails to comply with the provisions of this subtitle, and the Secretary contemplates instituting criminal proceedings against any person, he shall give appropriate notice to the person. Any person receiving notice shall be given an opportunity to present his views, orally or in writing, with regard to the contemplated proceedings.

This subtitle does not require the Secretary to report for prosecution, or for the institution of libel proceedings, any minor violation of the subtitle whenever he believes that the public interest is best served by a suitable written warning notice.

(c) The prosecuting attorney to whom any violation is reported shall institute appropriate proceedings in the proper court without delay.

(d) The Secretary shall give notice by publication of any judgment entered in any action instituted under the authority of this subtitle.

(e) The Secretary may enter, during regular business hours, any commercial premises, including any commercial transportation vehicle, where any pesticide is sold, offered for sale, stored or is being transported, to enforce the provisions of this subtitle.
