pyrethroid

synthetic chemical compound

Quick Summary

Pyrethroids are synthetic chemical compounds that mimic the insecticidal properties of pyrethrins, which are naturally derived from chrysanthemum flowers. These compounds act as contact poisons for insects and cold-blooded vertebrates.123

While pyrethroids are effective insecticides, they can accumulate in water and sediments, posing a toxicity risk to fish and aquatic invertebrates. Insecticides, including pyrethroids, are classified based on their chemical properties and how they affect insects. They are primarily used to control insect pests that damage crops or spread diseases.345
