What are biorational insecticides derived from?

Biorational insecticides are characterized by their origins, which are typically derived from biological or natural sources. This includes substances that may be extracted from plants, such as essential oils, or produced by microorganisms, including bacteria and fungi. These insecticides are designed to target specific pests with minimal impact on non-target organisms, promoting a more environmentally friendly approach to pest management. Their natural origin is fundamental to their classification and effectiveness in sustainable agricultural practices, allowing for pest control methods that align with integrated pest management strategies.
