Preservation of Food Sugar Beet via the Control of Rhizoctonia solani AG 2-2IIIB by Extreme Factors

Sugar beet (Beta vulgaris L.) is a valuable sugar-providing crop accounting for around 25% of global white sugar production. It an integral part the food industry. Several factors cause decrease in yield this crop. The infection phytopathogenic fungi one most hazardous. Though several methods to control Rhizoctonia solani have been developed, problem still not solved. Thus, goal work was investigate effect abiotic (pH, Eh, presence or absence O2) and biotic ones (microbial community) on fungal pathogen R. AG 2-2IIIB its protection. Microbiological were used conduct research. Thermodynamic calculations applied determine conditions necessary suppression 2-2IIIB. As result, comparison mediated efficiency growth carried out. Obtained data showed following: mainly provided via chemical buffers removal oxygen caused inhibition solani; values 5.5 ≤ pH 8.5, Eh −200 mV, inhibited growth. maintenance these microbial communities enhanced suppressive effect, bringing about death mycelium. study strains revealed inhibitory metabolites more effective
