Pyrethrum is a natural insecticide derived from the dried flowers of certain chrysanthemum species, primarily Chrysanthemum cinerariifolium and Chrysanthemum coccineum. The active compounds in pyrethrum are called pyrethrins, which are effective against a wide range of insects.
Pyrethrum contains six active compounds called pyrethrins, which target the nervous systems of insects. When an insect comes into contact with pyrethrum, the pyrethrins disrupt the nerve signals, causing paralysis and death. Pyrethrum is fast-acting and has a knockdown effect, meaning that insects die quickly after exposure.
Benefits of using pyrethrum for crop protection:
Natural: Pyrethrum is a naturally occurring substance, making it a good choice for people who are concerned about using synthetic pesticides.
Safe: Pyrethrum is relatively safe for humans and animals when used according to the label. It breaks down quickly in the environment and does not leave harmful residues.
Effective: Pyrethrum is effective against a wide range of pests, including aphids, beetles, caterpillars, flies, mosquitoes, and thrips.
Repellent: Pyrethrum also has a repellent effect, which can help to prevent pests from returning to an area.
Things to consider when using pyrethrum:
Pyrethrum can be harmful to bees and other beneficial insects. Be sure to avoid using it when bees are active or near flowering plants.
Pyrethrum can irritate the skin and eyes. Wear gloves and eye protection when handling it.
Pyrethrum breaks down quickly in sunlight and heat. Store it in a cool, dark place.
