What is the primary goal of using companion planting in pest management?

The primary goal of using companion planting in pest management is to repel pests and attract beneficial insects. This practice involves strategically planting different crops in proximity to one another to create a natural ecosystem that helps to reduce pest populations and enhance plant health. Certain plants can emit scents or produce compounds that either deter harmful pests or lure in beneficial insects, such as pollinators and natural predators of pests.

For instance, planting marigolds alongside vegetables can deter nematodes, while herbs like basil can attract bees and other beneficial organisms. By integrating these plants thoughtfully, gardeners and farmers can cultivate a more balanced environment that minimizes the need for chemical pesticides and promotes sustainable agriculture practices.

While improving soil quality, increasing crop yield, and providing shade for plants can also be beneficial outcomes of planting strategies, they do not specifically align with the main focus of companion planting in pest management, which is to enhance pest control through the beneficial interactions between different plants.
