In the article the tasks have been set on the inventory of the species composition of fungi of the genus Alternaria Nees ex Walroth - pathogen of various Alternaria diseases of vegetable crops in Uzbekistan. More than 200 isolates were collected and about 150 monosporous pure cultures were obtained from them. According to preliminary data, they belong to 15 species of the genus Alternaria and have been isolated from the 12 most important crop species. It was found that a more accurate identification of species requires the study of a wide range of morphological and biochemical traits. The article discusses the issue of infection of vegetable seeds in Uzbekistan. The composition of micromycetes living on seeds of vegetable and green crops was revealed. In total, 21 species were recorded, of which 9 species includes to Alternaria genus.
