Biocontrol agents are natural organisms or substances used to manage pests and diseases in agriculture and horticulture. These agents can include beneficial insects, microorganisms, and plant extracts that help reduce the population of harmful pests without relying on synthetic chemicals. By promoting ecological balance, biocontrol agents contribute to sustainable farming practices. Common examples of biocontrol agents include ladybugs, which feed on aphids, and Bacillus thuringiensis, a bacterium that targets specific insect larvae. Utilizing these agents can enhance crop health and yield while minimizing environmental impact, making them an essential component of integrated pest management strategies.
