When Rotenone was deveoloped:
Rotenone has been used for centuries to kill fish for food,by people who live in areas where it is derived from, but was only officially registered by the U.S.A. as a piscicide in 1947. It has been used in North America since the 1930s in Fisheries management as a piscicide.
What Rotenone is used for:
Rotenone is mostly used to control aphids, raspberry beetles and sawflies, but it is rarely used as it can have adverse affects on beneficial species and pests. It is also used to control ticks, caterpillars, flies, etc, and to kill lice in many shampoos for dogs, cattle and sheep. Rotenone is the most common pesticide used to kill fish populations. Poinsoned fish can be cured only by being put in untreated water.
The concentrate or the powdered root of Rotenone can be used in products, and because it is a naturally occuring chemical, it is permitted for some restricted use in organic farming.
Rotenone is rapidly broken down in sunlight, so it should be used in the evening as it is more effective.
With the intention of restoring native fish or frogs, Rotenone is used in the removal of non-native fish species from small, concentrated areas. It is also used to control invasive species that may endanger the environment or the economy.
Why Rotenone is used:
Because Rotenone degrades rapidly, it does not stay in the environment for long. It does not penetrate well through soil, and dissapears from streams quickly- therefore it does not pose a threat to ground water.
The small amount of Rotenone used in fish control projects does not affect humans and mammals, and when Rotenone is used according to the directions on EPA-approved Rotenone product labels, there are no known health impacts on human health. These factors contribute to why Rotenone is used.
