Abstract:Postharvest fruits and vegetables are easy to be infected by pathogens during storage，transportation and marketing.Trichoderma and its metabolites can inhibit the growth and reproduction of common pathogens in fruits and vegetables，and play an important role in antibacterial，antiseptic and preservation.Moreover，Trichoderma is non-toxic，harmless and non polluting to the environment，which is a promising biological preservation method.In this paper，the application and research progress of Trichoderma in fruits and vegetables preservation in recent years were reviewed，including the types of Trichoderma，the preservation mechanism of Trichoderma，the application effect of Trichoderma and its metabolites in fruit and vegetable preservation，the commercial products of Trichoderma，and the problems and solutions in the development of fresh-keeping products by Trichoderma.
