Abstract: Agro-products were decayed easily after infected by pathogenic fungi which can lead to decline of sensory, nutrition and commercial quality.Although fungi growth and mycotoxin-producing are two different processes, the effective prevention and control measures can inhibit both physiological processes.The physical method is easy-to-use and it's also a green control measure without any chemical pollution. Some physical techniques can not only remove the pathogenic fungi and inhibit the production of their toxins effectively, but also can enhance the resistance to the fungus, improve quality, and extend the storage and shelf life of agro-products. In this paper, the present situation of widely applicable physical techniques included heat, radiation and UV treatment were reviewed, and the control effect of the three physical technologies for fungus and mycotoxin were also summarized, so as to provide theoretical reference for other researchers in this field.
