What is the primary advantage of using biopesticides over conventional pesticides?

The primary advantage of using biopesticides over conventional pesticides lies in their generally fewer negative environmental impacts. Biopesticides are derived from natural materials such as plants, bacteria, and minerals, and they tend to be more target-specific, which reduces the risk of harming non-target organisms, including beneficial insects, wildlife, and humans. This biological basis allows for a less harmful approach to pest management, contributing to more sustainable agricultural practices.

While it's true that some biopesticides may be more expensive or slower to act than conventional pesticides, their environmental benefits, including lower toxicity and reduced persistence in the environment, are significant factors in their favor. Regulations are still applicable to biopesticides, ensuring that they are used safely and effectively, and their development and marketing are also subject to oversight. Therefore, their reduced negative environmental impact is the most compelling reason for their use in pest management.
