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