Which of the following is considered a more environmentally friendly pest control approach?

Choosing biological control as a more environmentally friendly pest control approach is based on its methodology of using natural organisms to manage pest populations. This technique leverages predators, parasites, or pathogens to target specific pests, thereby reducing the reliance on synthetic chemicals. Biological control helps maintain ecological balance while minimizing harm to non-target species and the environment.

In contrast, chemical spraying often leads to pollution and can adversely affect beneficial insects, aquatic systems, and overall biodiversity. Mechanical weed removal involves physical actions such as hoeing or mowing, which, while potentially effective, may not be as sustainable long-term and can disturb soil ecosystems. Cultural controls, which include practices like crop rotation and varied planting times, are beneficial but may not directly employ natural predation mechanisms as effectively as biological control does.

By recognizing the benefits of biological control, it’s clear why this method is favored for its sustainable practices that align with environmental stewardship.
