Rotenone
鱼藤酮
Introduction: Rotenone is a selective, non-specific 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. The use of the pesticide for control of fish and in cranberries is restricted by the Environmental Protection Agency. 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. Rotenone is generally classified as a botanical insecticide. Rotenone is a general use pesticide.

ENVIRONMENTAL FATE
Rotenone breaks down readily by exposure to sunlight. Nearly all of the toxicity of the compound is lost in five to six days of spring sunlight or two to three days of summer sunlight. Rotenone is a highly active but short-lived photosensitizer. This means that an organism consuming the compound develops a strong sensitivity to the sun for a short time. A number of photodecomposition products are formed when bean leaves are exposed to light. It is also sensitive to heat with, much of the rotenone quickly lost at high temperatures. Rotenone is rapidly broken down in soil and in water. The half-life in both of these environments is between one and three days. Because of its short half-life and because it does not readily leach from soil, it is not expected to be a groundwater pollutant.
Usage: Rotenone was produced by extraction from Derris roots, Derris root has long been used as a fish poison and its insecticidal properties were known to the Chinese well before it was isolated by E. Geoffrey. It is a insecticide of low persistence now used mainly in fish management and for the control of a wide range of arthropod pests including aphids, thrips and spider mites. Also has livestock applications.
Application: Biochemistry Respiratory inhibitor acting by inhibiting electron transport at NADH-ubiquinone oxidoreductase (complex I). Selectivity appears to originate from different rates of detoxification. Mode of action Selective non-systemic insecticide with contact and stomach action. Secondary acaricidal activity. Uses Now used mainly to control fish populations in fish management; applied at 0.005-0.250 ppm.
