Relating to a prohibition against the cultivation of castor beans; creating a criminal offense.

HB 3519 prohibits the commercial cultivation of castor beans (Ricinus communis) in Texas, defining "cultivate" to include planting, growing, and harvesting. It directly affects commercial growers who would otherwise produce castor beans, which contain the toxin ricin. The bill creates a Class C misdemeanor offense for violating this prohibition, punishable by fine but not jail time. The law takes effect September 1, 2025, and amends the Agriculture Code to add Chapter 129 specifically addressing castor beans.
