Which of the following is a common method of organic pest control?

Introducing beneficial insects is a common method of organic pest control because it harnesses natural predators to manage pest populations effectively. This approach fosters a healthy ecosystem by utilizing insects such as ladybugs or lacewings, which feed on pest species like aphids and caterpillars. By promoting biological diversity and enhancing the presence of these beneficial organisms, gardeners and farmers can reduce reliance on synthetic chemicals and maintain a balanced environment that supports plant health.

In contrast, using chemical pesticides and soil fumigation are methods more aligned with conventional agriculture, focusing on synthetic substances that may harm both beneficial organisms and the broader ecosystem. Similarly, using synthetic fertilizers can lead to nutrient runoff and various environmental issues, diverging from organic practices that emphasize natural soil enrichment. Thus, the method of introducing beneficial insects aligns with organic principles and sustainable agriculture practices.
