Food & Agr. Code, § 52851

The Legislature hereby declares that the purposes of this chapter are to promote, encourage, aid, and protect the planting and growing of cotton in the State of California; that it believes that these purposes can best be accomplished by restricting within certain areas the planting and growing of but two types of cotton, which are Acala and Pima; that, by this means, it is possible to bring the cotton-growing industry in the state to its highest possible development and to ensure the growing of the most superior varieties of cotton; that the planting of pure seed is essential to the production of more marketable and better grades of cotton and cottonseeds, and for the production of grades of fiber best suited for manufacturing purposes; and that the planting of impure seeds or plants, other than those authorized in these areas, is an economic harm and loss to the planter thereof and an irreparable injury to the adjoining or neighboring growers.
