Rotenone is a selective, non-specific botanical insecticide with some acaricidal properties. Rotenone is used in home gardens for insect control, for lice and tick control on pets, and for fish eradications as part of water body management. Rotenone is a rotenoid plant extract obtained from such species as barbasco, cub, haiari, nekoe, and timbo. These plants are members of the pea (Leguminosae) family. Rotenone-containing extracts are taken from the roots, seeds, and leaves of the various plants. This chemical has been used in one form or another as a crop insecticide since 1848 and has been recognized as a registered pesticide in the United States under the Federal Insecticide Fungicide Rodenticide Act (FIFRA) since 1947. Rotenone has also been found to also have properties of a pescicide where it is generally used to rid environments of non-native predatory fish species. Rotenone is a commonly used neurotoxin to produce in vivo and in vitro Parkinson's disease models. Rotenone is the classical inhibitor of NADH: ubiquinone oxidoreductase.
