Pyrethrin I has become a cornerstone of the biopesticide industry, driven by the global shift toward sustainable, plant-based crop protection and public health solutions. Its rapid knockdown effect on a broad spectrum of insects, combined with low mammalian toxicity, makes it a preferred active ingredient in both agricultural and consumer insecticide formulations.
Chemically, Pyrethrin I is one of the six active esters found in pyrethrum extract, obtained from the flowers of Chrysanthemum cinerariifolium. It is the primary knockdown agent, acting on the insect nervous system by modulating sodium channels, leading to immediate paralysis and mortality. The compound is a viscous, yellow to amber liquid with a characteristic odor, and it is typically standardized as part of a total pyrethrin complex.
Our Pyrethrin I is offered as a high-purity extract standardized to ≥50% total pyrethrins, ensuring consistent potency for formulators. It is widely used in crop protection, animal health, and household insecticides where fast action and environmental compatibility are critical.
Pyrethrin I is a natural ester derived from the esterification of chrysanthemic acid with pyrethrolone. It constitutes approximately 35-45% of the total pyrethrin content in pyrethrum extract, depending on the source and extraction method. The extract also contains Pyrethrin II, cinerins, and jasmolins, which contribute to the overall insecticidal activity. Our product is a refined extract that maintains the natural balance of these components, with Pyrethrin I as the major active.
Unlike synthetic pyrethroids, Pyrethrin I is biodegradable and breaks down rapidly in sunlight and soil, leaving no harmful residues. This makes it ideal for organic farming and integrated pest management (IPM) programs. The extract is stabilized with antioxidants to prevent degradation during storage and handling.
