Potato cultivation faces significant challenges from various pests and diseases, including insect infestations, fungal infections, and viral diseases, which can severely impact yield and crop quality. This study provides a systematic review of the application of biological control agents (BCAs) as sustainable alternatives to chemical pesticides in managing potato pests and diseases. It outlines the types of microbial control agents (such as fungi, bacteria, and viruses), natural predators and parasitoids, with a focus on their mechanisms of action, including antagonism, induction of systemic resistance, and competitive exclusion. The study also evaluates the effectiveness of integrating BCAs into integrated pest management (IPM) programs through field trials and case studies. The research highlights the importance of biological control agents in promoting sustainable potato cultivation and provides practical recommendations to enhance crop resilience and reduce dependence on chemical pesticides.
