Oilseed flax is a rather new crop for Kazakhstan, as it has recently been cultivated there. Cultivation of oilseed flax has been growing in Kazakhstan for some years. The article presents the data on the study of soil actinomycetes on the growth and development of oilseed flax, as well as the spread of root rot, depending on the use of various biologics based on different cultures of actinomycetes. It has been found that many cultures can limit the spread of root rot in the initial stages of growth and development of oilseed flax by 34-65%. It has been noted that biologics based on actinomycetes can increase the immunity and the yield of oilseed flax. S. pratensis 15 culture in pure form and the consortium of actinomycetes S. ambofaciens 40 strain + S. platensis strain 44 + Act. spp. strain 46 are recommended to create biologics.
