Insecticidal effect of herbal and aromatic extracts: myth or reality?

Abstract

The concern of the people for obtaining rich harvests and with the least expensive means has been and is continuous. The man of the past centuries, being more connected to nature than the present man and having the popular knowledge about the natural phenomena and about the plant species from the spontaneous flora, often used different plants in the control of the pests from the agricultural crops. Modern man, forced to return to nature, has devoted himself to the study of plants with combat potential, the first fruits of his work being then materialized in a series of synthetic products called pyrethroids, after the plant that provided them with information and substance: Piretrum cinerareifolium.
