It is in the interest of the public welfare of the State of Texas that the producers of any agricultural commodity be permitted and encouraged to develop, carry out, and participate in programs of research, disease and insect control, predator control, education, indemnification, and promotion designed to encourage the production, marketing, and use of the agricultural commodity. The purpose of this chapter is to authorize and prescribe the necessary procedures by which the producers of an agricultural commodity grown in this state may finance those programs. The programs may be devised to alleviate any circumstance or condition that serves to impede the production, marketing, or use of any agricultural commodity.
