Which pest management strategy involves using plants that naturally repel certain pests?

Companion planting is a pest management strategy that focuses on the practice of growing different plants in close proximity to benefit one another. This method takes advantage of the natural properties of certain plants that can repel pests or attract beneficial insects. For instance, some plants may emit scents that deter insects that are harmful to nearby crops, while others may attract predators of those pests.

This approach not only helps in managing pest populations but also enhances plant growth and productivity through improved pollination and increased availability of nutrients. Companion planting is a sustainable method that promotes biodiversity and reduces the need for chemical pest control measures, creating a more balanced ecosystem in the garden or field.

In contrast, crop rotation involves changing the type of crop grown in a particular area each season to disrupt the life cycles of pests and diseases; mechanical control refers to physical methods of pest removal (like traps or barriers); and cultural practices include a variety of methods like soil management and irrigation that influence pest prevalence but do not specifically involve plant associations.
