Intercropping disrupts the uniform distribution of a single crop species, making it less attractive to pests and diseases that target specific crops. By alternating rows of different crops, pests and diseases are less likely to spread rapidly throughout the entire field, reducing the risk of widespread damage and enhancing crop resilience.

Intercropping can deter the spread of pests and diseases by disrupting their host plants’ monoculture habitats. Mixing different crops creates a barrier that pests must navigate, reducing their ability to locate and infest specific crops. Additionally, intercropping with plants that emit repellent odors or compounds can further deter pests, while diverse plantings can also support natural predators that control pest populations.
