Which of the following is a characteristic of biodegradable pesticides?

Biodegradable pesticides are designed to break down into harmless substances over time, minimizing their environmental impact. One of the key characteristics of these pesticides is their low toxicity to non-target organisms, which means that they pose less risk to beneficial insects, wildlife, and humans compared to more persistent chemicals. This quality makes biodegradable options a preferred choice for integrated pest management, as they provide pest control while also protecting the ecosystem.

In contrast, options that highlight high persistence in the environment or high water solubility contradict the fundamental principles of biodegradability. Highly persistent pesticides would remain in the environment for extended periods, posing greater risks to non-target organisms. High water solubility could lead to greater runoff and contamination of water sources, further benefiting neither the environment nor non-target species. Additionally, stating that biodegradable pesticides are non-effective against pests undermines their purpose, as effective biodegradable pesticides are designed specifically to target pests while being safe for the surrounding ecosystem.
