What defines a biopesticide?

A biopesticide is specifically defined as a pesticide derived from natural materials such as plants, animals, bacteria, and minerals. These substances are typically more environmentally friendly compared to conventional synthetic pesticides and can target specific pests without harming beneficial organisms. Biopesticides are recognized for their potential to reduce risks to human health and the environment, making them increasingly popular in integrated pest management strategies.

The other options highlight concepts that, while relevant to agricultural practices, do not align with the definition of a biopesticide. For instance, synthetic compounds are typically associated with traditional chemical pesticides and not the natural basis of biopesticides. Genetically modifying plants relates to biotechnology, which is a different area of focus entirely. Lastly, soil enhancement techniques, while critical for crop productivity, do not pertain directly to the use of biopesticides. Thus, the most accurate definition of a biopesticide is one that emphasizes its derivation from natural materials.
