  2.  The pesticides on the list of restricted use pesticides, as determined by the federal agency having jurisdiction over the classification of pesticides, shall be so restricted in the state of Missouri.  The director shall publish, at least annually, a list of pesticides that have restricted uses.  Such publication shall be made available to the public upon request.  If the director determines that a pesticide, when used in accordance with its directions for use, warnings, and cautions, and for uses for which it is registered, may cause, without additional regulatory restrictions, unreasonable adverse effects on the environment, including injury to the applicator or other persons, the pesticide shall be used only by or under the direct supervision of a certified applicator.  Such pesticides may be subject to other restrictions as determined by the director, to include the time and conditions of possession and use.

  3.  No regulation, or any amendment or repeal thereof, provided for in sections 281.010 to 281.115 shall be adopted, except after public hearing giving an opportunity to the public to be heard, to be held after no less than thirty days' prior notice of the date, time, and place of hearing, to be given by regular mail to any person who has registered with the director for purposes of notice of such public hearings, in accordance with procedures prescribed by the director.

  4.  At any hearing, opportunity to be heard shall be afforded to any interested person upon written request received not later than twenty-four hours prior to the hearing, and may also be afforded to other persons.  In addition, any interested person, whether or not heard, may submit within seven days subsequent to the hearing a written statement of views.  The director may solicit the views in writing of persons who may be affected by, or interested in any proposed regulation.  Any person heard or represented at the hearing, or making written request for notice, shall be given written notice of the action of the director with respect to the subject thereof.

  5.  No rule or portion of a rule promulgated under the authority of this chapter shall become effective unless it has been promulgated pursuant to the provisions of section 536.024.
