Herbicide resistant (HR) rice biotechnology provides control of the red rice weed in commercial rice. This technology may alter the traditional soybeans-rice rotation practice in southern United States. Mathematical programming is used to analyze the effects of HR rice on the current rotation system. Optimal crop rotations subject to weed dynamics and technology costs are identified.

Key words: Biotechnology; herbicide resistant; mathematical programming; red rice; rice; rotation; soybeans; technology.
