Introduction. Microbial strains can be used as raw materials in environmental bioremediation and in formulating bioproducts for agriculture [1,2,3,4]. One way to limit the effects on the environment generated by the use of synthetic pesticides in sugar beet culture consists of the use of microbial bioproducts.
Materials and methods. Microorganisms with the potential to be used for this purpose were selected from the sugar beet rhizosphere and tested in vitro and in vivo on two types of standardized phytopathogens: Rhizoctonia sp. and Sclerotiorum sp. [5,6,7,8]. The microorganisms that determined the highest in vitro inhibition rate of the two phytopathogens were characterized by sequencing the 16S RNA gene. In vivo tests were performed in the field on Beta vulgaris var. saccharifera.
Results and discussion. Molecular analysis showed that the microorganisms selected from the sugar beet rhizosphere belong to the genus Bacillus. The results obtained from in vivo tests with bioproducts made from the selected Bacillus strains showed that: (1) these can inhibit the effects of the diseases associated with the presence of Sclerotiorum rolfsii and Rhizoctonia solani up to 70%; (2) these can favor the development of sugar beet plants with an average value of 10%.
Conclusions. Certain microbial species selected from the sugar beet rhizosphere can be used to obtain bioproducts with properties of biocontrol and plant growth promotion, with low impact on environmental factors.
