Tanacetum Cinerariifolium Extract Pyrethrum Pyrethrins Pyrethrin

Pyrethrins are plant source pesticides extracted from pyrethrin plants, which have high efficiency, broad spectrum, low toxicity, anti-feeding and repellent effects on pests, and are not easy to produce resistance to pests, and are widely used in the field of health insecticide.

Pyrethroins are a complex mixture of six main ingredients, These include pyrethrins I (pyrethrins I), Pyrethrins II (pyrethrins II), cinerin I (cinerin II), jasmolin I (jasmolin I), and Jasmolin II (Jasmolin II). Among them, pyrethrin I and pyrethrin II are its main components and have insecticidal activity.

Pyrethrin has tactile and stomach toxic effects, effective against a variety of pests, such as aphids, mites, moths, jumping thyroid and so on. Its insecticidal mechanism mainly destroys the nervous system of insects, resulting in the death of pests. In addition, pyrethrin can also interfere with the normal recognition of plants by insects, thus reducing the damage of pests to plants.

It should be noted that pyrethrin is toxic to fish and other aquatic organisms, and special attention should be paid to avoid polluting the water body when used. At the same time, under high temperature and high humidity environment, the insecticidal effect of pyrethrin will be reduced, so pay attention to environmental conditions when using.
