To eliminate cogongrass and prevent regrowth, the rhizomes must be destroyed. It has been shown that an integrated approach that combines burning, tillage (mechanical disturbance), and chemical applications provide the best solution for cogongrass management.

They are (listed in order of decreasing strength):(4) gravitational force(2) electromagnetic force(1) strong nuclear force(3) weak nuclear force. The electromagnetic force is a very strong, long-range force with unlimited range that acts between any two objects possessing an electric charge. It is the fundamental interaction that binds electrons to nuclei to form atoms and binds atoms together in molecules and solids.
