Which of the following is NOT a characteristic of bio pesticides?

The characteristic that bio pesticides generally have lower efficacy compared to synthetic pesticides is not accurate, making it the correct choice in this context. Bio pesticides are derived from natural materials like plants, bacteria, fungi, and minerals, and are often designed to target specific pests while minimizing harm to non-target organisms.

While it is true that some bio pesticides may have a different efficacy profile compared to synthetic options, they can be highly effective under certain conditions, especially in integrated pest management systems. Their effectiveness is influenced by various factors including the type of pest, the environment, and the specific bio pesticide formulation used.

In contrast, the other characteristics highlight the benefits of bio pesticides, emphasizing their natural origins and environmentally friendly aspects. This makes them an increasingly preferred choice in sustainable agriculture, despite the perception that they may sometimes be less potent than conventional synthetic pesticides.
