Pyrethrum flowers and pyrethroid insecticides

Environmental Health Perspectives

|February 1, 1980

Summary

This summary is machine-generated.

Natural pyrethrins from Chrysanthemum cinerariifolium are low-toxicity insecticides. Synthetic pyrethroids, derived from these natural compounds, offer enhanced potency and stability for crop protection.

Background:

Pyrethrins are natural insecticides derived from the flowers of Tanacetum or Chrysanthemum cinerariifolium.
These natural compounds are known for their low mammalian toxicity and nonpersistent environmental profile.

Observation:

Synthetic analogs, termed pyrethroids, have been developed through chemical modifications of natural pyrethrins.
Pyrethroids represent a significant advancement in insecticide technology.

Findings:

Pyrethroids exhibit increased potency and stability compared to their natural pyrethrin precursors.
These synthetic compounds retain the favorable safety characteristics of natural pyrethrins.

Implications:
