Which of the following best describes biopesticides?

Biopesticides are indeed best described as naturally derived substances that control pest populations. This definition captures the essence of biopesticides, which are typically derived from natural materials such as plants, bacteria, fungi, and minerals. These substances can offer effective pest control while posing minimal risk to human health and the environment, making them an essential component of integrated pest management strategies.

Synthetic chemicals, which are often toxic, aim to indiscriminately kill a broad spectrum of pests, contrasting with the targeted nature of biopesticides. While biopesticides can be used in agricultural settings, they are not limited to this sector; they may also be employed in residential and public health contexts, reflecting a wider application. While some pests might develop resistance to certain biopesticides over time, this is not the defining characteristic of biopesticides; rather, their natural origin and mode of action are what set them apart.
