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

Biological pest control is a prevalent method used in organic farming due to its alignment with the principles of sustainability and environmental health that underpin organic practices. This approach involves utilizing natural predators, parasites, or pathogens to manage pest populations, thereby reducing the reliance on synthetic chemicals. For example, introducing ladybugs can help control aphid populations, offering an effective and eco-friendly solution to pest issues.

In organic farming, the emphasis is placed on maintaining biodiversity and enhancing the ecosystem, which biological control methods support effectively. By leveraging the natural relationships between species, farmers can achieve pest management without harming beneficial insects, soil health, or the surrounding environment.

On the other hand, chemical pesticides and genetically modified organisms do not fit within organic standards, as they can disrupt ecological balance and pose risks to health and environment. Aerial spraying is typically associated with conventional agriculture and raises concerns about drift, unintended exposure, and impacts on non-target organisms and habitats, making it less compatible with the organic farming philosophy.
