What is the main purpose of a selective pesticide?

The main purpose of a selective pesticide is to target specific pests while sparing others. Selective pesticides are designed to interfere with particular biological processes or traits of certain pests, which allows them to control pest populations effectively without harming beneficial insects, plants, or organisms in the environment. This targeted approach minimizes ecological disruption and can lead to more sustainable pest management practices.

By focusing on specific pests, selective pesticides can reduce the risk of developing resistance in non-target pest populations and help to maintain the balance of the ecosystem. This is in contrast to broad-spectrum pesticides, which aim to eliminate a wide variety of pests but can also negatively impact beneficial species. The correct answer highlights the importance of using chemicals in a precise manner that supports environmental health and agricultural sustainability.
