Which method is often used for pest control in organic farming?

Biological control using natural predators is a commonly employed method in organic farming because it aligns with the philosophy of reducing reliance on synthetic chemicals. This approach utilizes beneficial organisms, such as insects or microorganisms, to control pest populations naturally, promoting a balanced ecosystem within the farming environment. For instance, introducing ladybugs can help control aphid infestations without harming the broader ecological system.

This method not only helps manage pest populations effectively but also supports biodiversity and reduces the potential for chemical resistance among pests. By focusing on natural pest control strategies, organic farming enhances soil health and maintains the integrity of the produce, which are fundamental goals of organic agricultural practices.

The other options, such as using synthetic pesticides, implementing monoculture practices, and resorting to mechanical pest traps, do not fit well within the organic farming framework. Synthetic pesticides contradict organic principles by introducing harmful chemicals, while monoculture can lead to increased pest susceptibility due to reduced genetic diversity. Mechanical pest traps may be used, but they are generally less emphasized compared to biological methods in organic farming.
