Missouri Revised Statutes Title XVII. Agriculture and Animals § 263.190. Owners to control noxious weeds--notice procedure--penalty--sale of noxious weeds prohibited

1. As used in sections 263.190 to 263.474, “noxious weed” means any weed designated as noxious by rules promulgated by the director of the department of agriculture. The department shall maintain a list of such noxious weeds and shall make such list available to the public. The department of agriculture shall promulgate rules necessary to implement the provisions of this subsection. Any rule or portion of a rule, as that term is defined in section 536.010, that is created under the authority delegated in this subsection shall become effective only if it complies with and is subject to all of the provisions of chapter 536 and, if applicable, section 536.028. This subsection and chapter 536 are nonseverable and if any of the powers vested with the general assembly pursuant to chapter 536 to review, to delay the effective date, or to disapprove and annul a rule are subsequently held unconstitutional, then the grant of rulemaking authority and any rule proposed or adopted after August 28, 2011, shall be invalid and void.

2. It shall be the duty of every owner of lands in this state, including but not limited to any person, association of persons, corporation, partnership, state highways and transportation commission, state department, state agency, county commission, township board, school board, drainage board, governing body of an incorporated city, railroad company or other transportation company and such company's authorized agent, and any person supervising state-owned lands to control all noxious weeds growing thereon so often in each and every year as shall be sufficient to prevent such noxious weeds from going to seed. If any owner of such land shall knowingly allow any noxious weeds to grow thereon, such owner shall forfeit and pay the sum of one hundred dollars to the county commission for every such offense, and such sum forfeited plus court costs may be recovered by civil action instituted by the prosecuting attorney in the name of the county commission before any associate circuit judge of the county in which the offense is committed. All sums recovered by virtue of this section shall be paid to the use of the county control fund.

3. Before initiating any civil action under this section, the prosecuting attorney of the county in which the land, or the greater part thereof, is located shall notify the owner of the land of the requirements of this law, by certified mail, return receipt requested, from a list supplied by the officer who prepares the tax list, and shall allow the owner of the land fifteen days from acknowledgment date of return receipt, or date of refusal of acceptance, as the case may be, to initiate control of all such plants growing upon the owner's land. Failure of the owner to initiate control of such plants within the fifteen-day period shall be prima facie evidence of the owner's knowledge that the owner is in violation of this law, and each fifteen days the violation continues after the initial fifteen-day period shall, for the purpose of forfeiture and penalty herein, be considered a separate offense.

4. All sales of noxious weed species are prohibited.
