Also known asderris powderandtuba root(in Indonesia),[2]it was formerly used as anorganicinsecticide used to control pests on crops such as peas. However, due to studies[which?]revealing the extreme toxicity of rotenone to which the powder is often refined, it is unsafe: in spite of its popularity with organic growers.[3][better source needed]
Derris root, when crushed, releases rotenone. Some native residents of Fiji and New Guinea practice a form of fishing in which they crush the roots and throw them into the water.[4]The stunned or killed fish float to the surface where they can be easily reached.[5]
Despite its toxicity,Derrisis used as a food plant byLepidopteranlarvae[6]includingBatrachedra amydraula.
