“…Zhao et al (2014) found that Bacillus subtilis isolated from wheat grains have antagonistic activity against F. graminearum mycelial growth, sporulation and toxin production as reason of destroying cell structure organelles and cytoplasm followed by cell death due to antifungal activity associated with production of chitinase and surfactins. Balah et al (2018) reported that antifungal activity of some rhizobacterial isolates metabolites of Bacillus cereus and Pseudomonas geniculata were the most efficient isolates could be used as a good element to control Bipolaris sorokiniana in plant root rot disease. Bacillus sp.…”

Rhizoctonia oryzae Kühn and Fusarium spp. were isolated from wheat plants exhibiting typical root and crown rot symptoms from different districts at Sharkia Governorate, Egypt during 2015/ 2016 growing season. Pathogenicity test revealed that B. sorokiniana was the most virulent one causing preemergence damping-off followed by Fusarium culmorum. In addition, F. culmorum was the most virulent one responsible for post-emergence damping-off incidence. Rhizoctonia oryzae showed the highest percentage of root rot, Moreover, F. culmorum and B. sorokiniana showed the highest percentage of disease incidence. In the same trend, F. culmorum induce the highest percentage of disease severity. In vitro, Trichoderma sp. bio-agent and its culture filtrate were the most effective treatment that reduced mycelial growth of the tested fungi. In vivo, it decreased pre and postemergence damping off, root rot, disease incidence and disease severity compared with the control. In addition, the obtained results indicated a significant increase on healthy survival plants and significantly improved the plant growth parameters i.e. fresh and dry weights of shoots and roots, plant height, spike length and 1000 grain weight. In vitro, Score and Amistar-top fungicides were the most effective in inhibiting the mycelial growth of R. oryzae followed by Amistar-top on B. sorokinana and Score on F. culmorum. Score was the most effective treatment revealed the highest percentage of healthy survival plants followed by Amistar-top and gave the highest protection against root and crown rot disease as shown by disease incidence and severity percentages.

The taxonomic structure of the microbiome of southern chernozem compared to virgin soil was studied in the stationary experiment on the use of microbial preparations in the conditions of traditional for the steppe part of the Crimea and each culture of the five-field crop rotation of the farming system and no-till. Among 823 genera it was revealed 7 dominant ones: Candidatus Nitrososphaera, Rubrobacter, Flavisolibacter, Segetibacter, Bacillus, Balneimonas, Skermanella. The low level of cellulose-decomposing bacteria of the genus Cellulomonas was remarked in southern chernozem. The highest proportion of the representatives of this genus was observed in virgin soil (0.55 %), while the farming systems contributed to its decline in 1.3-1.6 times. Microorganisms of the genera Erwinia and Xanthomonas with phytopathogenic properties were found with a minimum proportion in communities from 0.003 % to 0.014 % and 0 – 0.005%, respectively. The complex metagenomic analysis of the taxonomic structure of the soil microbiome allowed us to establish that the use of microbial preparations reduces the negative impact of the no-till farming system on the microbiocenosis of southern chernozem and improves its environmental feasibility in the Crimean steppe.
