In the last few years, beet-growing farms in Kazakhstan have suffered great losses from widespread diseases of sugar beet, which lead to the death of plants in the field. we selected two regions, in particular, the farms of Zhambyl and Almaty regions,as these areas have large sugar beet processing plants. The purpose of this work is to study the phytosanitary condition of zoned varieties of sugar beet families obtained from beet-growing farms in Almaty and Zhambyl regions before planting. The objects of research were soil samples selected in beet-growing farms of Almaty and Zhambyl region. Quantitative accounting of microorganisms was carried out by seeding on nutrient media selected in accordance with their type. Thus, some features of formation of pathogenic complex of microscopic fungi in soil in beet-growing farms of Almaty and Zhambyl regions are revealed. Soil microbial communities in two areas are represented by microorganisms such as bacteria genera: Pseudomonas, Bacillus, Mycobacterium, Mycococcus, Pseudobacterium, Lactobacterium. It is shown that Bacillus and Pseudomona prevail in soil samples.It is established that the dominant species of microorganisms are: fungi genera: Fusarium, Alternaria, Penicillium which are included in the pathogen pathogen of root rot. On the basis of the obtained data, a protective and stimulating composition for reducing the incidence of sugar beet seeds before sowing will be developed in soil samples No. 1- 4 of Almaty.fungi of the genus Fusarium prevailed in the NSK region, and Botrytis prevailed in the Zhambyl region
