Biopesticides are distinguished from conventional pesticides primarily by their origin and specificity in targeting pests. They are derived from natural materials, such as plants, bacteria, and minerals, which allows them to often target specific pests while being less harmful to non-target organisms, including beneficial insects and the environment. This specificity is crucial as it reduces the chances of broad-spectrum damage often associated with conventional pesticides.

In contrast, conventional pesticides may be synthesized from synthetic chemicals or modified biological agents and typically have a broader spectrum of activity, which can lead to unintended effects on non-target species. This makes biopesticides an appealing option for sustainable farming practices and integrated pest management strategies, as they support ecological balance while effectively controlling pest populations. Additionally, the notion that biopesticides have no ecological impact is misleading; while they may have a lower impact compared to conventional pesticides, they can still affect ecosystems, especially if used improperly or in excessive amounts.
