What are the advantages of using companion planting in pest management?

The advantage of using companion planting in pest management primarily revolves around its ability to deter pests, attract beneficial insects, and improve the overall health of crops. This method utilizes the natural relationships between various plant species to enhance growth and protect against pest infestations.

Companion plants can emit certain scents or produce specific chemicals that repel pests, making it difficult for harmful insects to locate their preferred host plants. Additionally, some companion plants are known to attract beneficial insects, such as pollinators or natural predators of pests, which can help maintain a balanced ecosystem in the garden or field. Moreover, planting compatible species together can enhance nutrient uptake, improve soil health, and foster a more resilient plant community. This, in turn, supports crop health and can lead to increased yields.

The other options do not accurately represent the outcomes associated with companion planting. While it can create a more diverse planting arrangement, this aspect is more of a secondary benefit rather than a primary advantage related to pest management. Companion planting does not guarantee complete pest elimination or a reduction in the need for fertilizers, as the need for nutrient supplementation may still apply depending on the specific conditions of the soil and the needs of the plants involved.
