What defines a biopesticide?

A biopesticide is defined as a pesticide derived from natural materials, which can include plants, bacteria, fungi, and other biological organisms. These substances are often used as alternatives to synthetic chemicals to manage pests. They function by utilizing natural mechanisms, such as interfering with the pest's life cycle or providing biological control through natural predators or pathogens.

The focus on natural origins is significant because biopesticides tend to have lower environmental impact and can enhance biodiversity. They are designed to target specific pests, reducing the harm to non-target organisms and minimizing the risks associated with chemical pesticide residues.

In contrast, options regarding synthetic materials, high application rates, or exclusive use in organic farming do not accurately describe biopesticides. Biopesticides can be used in both organic and conventional farming and are often valued for their efficacy at lower application rates, which helps promote sustainable agricultural practices.
