How does intercropping help with pest management?

Intercropping helps with pest management primarily by increasing biodiversity in a farming system. When different crops are grown together, it creates a more complex ecosystem that can disrupt the life cycles of pests. This diversity can attract beneficial insects that prey on pests or help to create physical barriers that deter pests from reaching certain crops. The varied plant species often have different growth habits, root structures, and chemical compositions, which can make it more challenging for pests that typically specialize in a single plant type to find suitable hosts.

Moreover, intercropping can also lead to improved soil health and resilience, further supporting plant health and reducing susceptibility to pest infestations. By fostering a diverse agricultural environment, intercropping plays a significant role in naturally regulating pest populations, ultimately reducing the need for chemical interventions in pest control.
