Biological control refers to the use of natural organisms to manage pests, diseases, and weeds that affect crops and ecosystems. These organisms may include beneficial insects, microorganisms, predators, parasitoids, or pathogens that naturally suppress harmful pest populations. Instead of relying on chemical pesticides, biological control supports natural ecological balance and long-term pest management. It is widely used in agriculture, horticulture, forestry, and aquaculture to protect plants while maintaining environmental sustainability. Farmers and agricultural specialists often integrate biological control methods into broader pest management strategies to reduce chemical usage, protect beneficial organisms, and maintain soil and crop health.
