Sumario:In recent years, the biological control of diseases in the agriculture has acquired great importance against the phytosanitary problems caused by the indiscriminate use of chemical pesticides, which has resulted in severe pollution problems to the environment and has generated resistance in pests, as well as the presence of new species of phytopathogenic microorganisms with a greater virulence. Biological control offers us an alternative approach for disease control in citrus plants because not only do they not leave chemical residues banned by most international markets, they help eliminate pathogens that often cannot be controlled by chemicals. Most biological control agents are more difficult to handle and apply than common chemical antimicrobials, especially when the combination of several factors is required to be effective or ecologically competent. However, the complexity of the modes of action of many biological control agents represents an advantage over chemicals agents since the pathogen will have greater difficulty in developing resistance to them. Despite the importance of citrus crops in the Colombian economy, there have not been enough studies on this regard. Thus it is considered important to focus on researching more about the control of postharvest phytopathogens in citrus, because it is a way to contribute to the reduction of losses and obtaining a harmless product, as required by NTC 4087 and 1264, which establish the minimum quality requirements of a disease-free fruit.
