Which category of pesticides is made from plant parts, such as Pyrethrum?

The category of pesticides made from plant parts, such as Pyrethrum, is identified as botanicals. Botanicals are derived from plants and possess insecticidal properties, often used in pest control due to their natural origins and generally lower toxicity to non-target organisms compared to synthetic alternatives. Pyrethrum, specifically, is extracted from the flowers of Chrysanthemum cinerariifolium and is effective against a wide range of insect pests.

Synthetic pesticides, on the other hand, are chemically manufactured and not derived from natural plant materials. Insect growth regulators are a specific class of pesticides that disrupt the growth and development of insects, but they do not primarily consist of plant-derived compounds. Non-selective herbicides are designed to kill a wide range of plants and are not limited to insect control, making them distinctly different from the botanical category. Thus, the classification of Pyrethrum as a botanical aligns with its origin from plant parts, solidifying the choice.
