Which of the following is a key characteristic of organic pesticides?

The key characteristic of organic pesticides is that they are derived from natural sources, which includes being sourced from plants, animals, and certain minerals. This characteristic emphasizes their connection to naturally occurring substances, distinguishing them from synthetic pesticides that are formulated through chemical processes. Organic pesticides often have a shorter environmental persistence and are designed to work in harmony with the ecosystem, promoting a more sustainable approach to pest management.

While some inorganic substances can be considered organic in the sense that they are naturally occurring minerals or metals, the primary focus is on those derived from biological sources. This characteristic reflects the commitment to using materials that are naturally found in the environment, aligning with the principles of organic farming and ecological balance. Thus, the answer highlights the importance of source material in defining organic pesticides.
