Biocontrol agents are living organisms that are used to control pests, pathogens, or weeds in agricultural, forestry, and environmental settings. These agents can include insects, fungi, bacteria, viruses, and other organisms that prey on or compete with harmful pests or pathogens in order to reduce their populations and mitigate damage to crops or ecosystems. Biocontrol agents are considered to be a more sustainable and environmentally friendly alternative to chemical pesticides, as they often have minimal impact on non-target organisms and do not leave harmful residues in the environment. Research in this area focuses on identifying effective biocontrol agents, understanding their interactions with target pests or pathogens, optimizing their use in different agricultural systems, and developing innovative strategies to enhance their efficacy. Overall, biocontrol agents offer a promising and ecologically sound approach to pest and disease management, and ongoing research in this area is aimed at further advancing their use as a key tool in integrated pest management practices.
