The main objective of this study is the isolation and morphological identification of fungi associated with soybean plants and from soil layers of soybean cultivated fields in Uzbekistan. As a result of a mycological investigation of 160 soybean plant parts sampled from field surveys, 95 saprotrophic and phytopathogenic fungal strains were isolated which have the following distribution according to species assignment: Alternaria spp. 3%, Cercospora kikuchii 3%, Mucor spp. 3%,Colletotrichum truncatum 3%, Botrytis cinerea 3%, F. Heterosporum 4%, Penissulium spp. 7%, Fusarium spp.8%,  Alternaria alternata 9%, Tirichoderma sp 9%,  Aspergillus niger 10%,  Fusarium culmorum 11%, Fusarium oxysporum 13%, Fusarium solani 14%.  As a result of mycological investigation of soil samples, total of 40 fungal isolates were recovered which have the following species assignment: Alternaria sp., Fusarium spp., Trichoderma sp. Fusarium oxysporum, Fusarium culmorum,  Alternaria alternata, Fusarium solani, Aspergillus niger, Penissulium sp. Mucor sp. The fungal isolates obtained in this study can be used to ease the development of the effective integrated management of soybean diseases in Uzbekistan.
