Compounds in the roots of the Derris ellipticaBenth. may be used as insecticides, pesticides and piscicides. The compounds may be called Derris extract or Rotenone. The latter is the name by which the derivative insecticide is known among organic gardeners in the United States of America.
Rotenone is mildly toxic to mammals, including humans. One reason for the lower toxicity levels lies in the difficulty for rotenone to be taken in by the gastrointestinal tract or through the skin. Because of its irritability, rotenone tends to be vomited back up before it can cause harm to mammals. Nevertheless, the U.S. Department of Agriculture's National Organic Program no longer approves the use of rotenone in certified organic production.
The mildness of the reaction doesn't carry over to other life forms. Specifically, rotenone is highly toxic to insects, fish and aquatic life. The reason lies in the ease with which it's taken in by the gills or the trachea.
The plant is native to southeast Asia. Other synonymous scientific names include Parraderris elliptica and Pongamia elliptica. Common names include Derris, oil tree, poison vine, tubaroot, and tubli.
The Green Hill Landscaping website does not mention whether non-organic or organic insecticides are used. Botanical insecticides may not be the best choice when active ingredients such as rotenone are used. For example, the active ingredient in question tracks back to the roots of Fabaceae family members and to the seeds and stems of the jicama vine plant, sources of toxicity in insects and such aquatic life as fish.

Insecticides in gardening or agriculture are used to reduce the population of an insect which is causing harm to the crop to an acceptable level. They can range from something as simple as an insecticidal soap (such as dish soap) to very complex and very poisonous commercial insecticides which kill all the insects in its application range.
