What are the benefits of using biopesticides?

Biopesticides offer a significant advantage in their reduced toxicity to non-target organisms, which means they pose a lower risk to beneficial insects, wildlife, and humans compared to traditional chemical pesticides. This feature makes biopesticides an appealing choice for sustainable agriculture and integrated pest management practices. Additionally, by minimizing chemical residues in the environment, biopesticides contribute to safer food production and help in meeting regulatory guidelines aimed at reducing chemical usage in farming.

While it is true that some biopesticides can be cost-effective, this is not a universal rule, as some may be more expensive than their chemical counterparts. The effectiveness of biopesticides can vary widely, and they are not always more effective than conventional pesticides when it comes to controlling certain pests or diseases. Training requirements can also depend on the specific biopesticide and its application method, so it is not accurate to state that they require less training overall. Therefore, the reduced toxicity and lower chemical residue associated with biopesticides clearly underscores their environmental and health benefits, making option B the most appropriate answer.
