California Code, Food and Agricultural Code (Formerly Agricultural Code) - FAC § 5552

Any cotton plant which is uncultivated or that is left from a previous season is presumed to harbor pests and as such is a public nuisance. This presumption is a presumption affecting the burden of producing evidence. If any such cotton plant is not destroyed in the manner established by regulation of the director, by March 1st of any year or by such earlier date as shall be proclaimed by the director as the beginning of a host-free period pursuant to Section 5781 of this code, it is subject anytime thereafter to all remedies which are or may be given for the prevention or abatement of nuisances.
