Rotenone is a chemical compound commonly used as a pesticide and a piscicide, meaning it is used to kill fish. Some alternative names for rotenone include Derrin, Cube root, and Tubanone. Other synonyms for rotenone include Barbasco, Paraderil, and Piscellin. Rotenone has been used for centuries by Indigenous peoples in South America as a natural insecticide, as well as for hunting and fishing. It is derived from the roots of several plants in the Leguminosae family, including derris, cube, and tuba. However, its use has become controversial due to its potential negative impact on the environment and human health.
