“…IGL1 isolated from common poppy showed 70% efficacy against the pathogen. It has been reported that disease severity is reduced in germinated soybean seeds infected with M. phaseolina treated with Stenotrophomonas sp (Santos et al, 2021). Stenotrophomonas maltophilia C3 strain used as a biocontrol agent against plant diseases due to its chitinase activity and this bacterial strain inhibited the conidy germination of Bipolaris sorokiniana and similarly suppressed the disease in field conditions (Zhang et al, 2000).…”

Macrophomina phaseolina is a soil pathogen known as charcoal rot and can cause up to 90% yield loss in sunflower under suitable conditions. The serious damage caused by chemicals used in the control of soil-borne pathogens to the environment and health has become one of the most important concerns in agriculture. Therefore, in our study, it was aimed to determine the in vitro antagonistic effects of various bacterial species against M phaseolina. A total of 38 bacterial strains were isolated from soil samples in the rhizosphere of Malva sylvestris (hibiscus), Vicia sativa (vetch), Cicer arietinum (chickpea), Papaver rhoeas (weasel), Carlina marianum (thistle), Glebionis coronaria (crown daisy) and Vicia faba collected from Urla district of İzmir. All bacterial strains exhibited antibiosis effect under in vitro conditions, but it was determined that 5 bacterial isolates among them showed a high inhibition zone and showed an average inhibition potential ranging between 55% and 74%. The most effective bacteria identified at species and genus level by Maldi biotyping (MALDI-TOF MS) were identified as Bacillus amyloliquefaciens, Stenotrophomonas sp. and Bacillus cereus (3 isolates), and these species showed that they can be important biocontrol agents in biological control against M. phaseolina.

“…They have been adapted to adverse environmental factors, resulting in their efficacy being maintained in field conditions. Furthermore, survival strategies of extremophiles are determined by the presence of unique qualities that are not found or less pronounced in other microorganisms [7]. Some of them are reported to be capable of secreting antibiotic substances to reduce the number of competing species [8].…”

Biological plant protection products are extensively utilized in agriculture owing to their safety, efficacy, and environmental friendliness. The utilization of these funds in locales with challenging weather patterns is constrained. In order to ensure the successful use of biological plant protection products, it is rational to search for microorganisms adapted to the specific soil and climatic conditions of the territory. The objective of the investigation is to evaluate the antagonistic and growth-stimulating properties of the consortium of extremophilic microorganisms of Kuzbass, and to conduct laboratory testing on oats (Avena sativa L.). The work used microorganisms isolated at the initial stages of the research, such as Leclercia sp., Sphingomonas paucimobilis, and Lactobacillus plantarum. The findings revealed that these microorganisms are capable of producing gibberellic acid, dissolving phosphates, and retaining atmospheric nitrogen. Furthermore, the co-cultivation of microorganisms facilitates the enhancement of these indicators. The negative impact of phytopathogens (Alternaria alternata (F-525), Fusarium graminearum (F-877) PH-1, Fusarium graminearum (F-892) and Fusarium sporotrichioides (F-902)) on oats in laboratory conditions was reduced by a consortium based on these microorganisms. Therefore, the consortium has the potential to develop commercial drugs. Field experiments are planned in the future.

During the years with acute epiphytotic conditions, infectious diseases of plants cause significant crop losses. To ensure the productivity of agricultural crops, pesticides are used, that is, substances of chemical nature that protect plants from phytopathogens. Widespread use of pesticides leads to contamination of soil and water resources, changes in the microbiome, disruption of normal plant growth and development. In order to minimize the anthropogenic impact on the territory of the agroindustrial complex and ensure the protection of cultivated plants from biotic stresses, environmentally safe analogues of chemical pesticides have been developed – biopesticides based on bacteria and fungi (have become more widespread), as well as viruses. The review, based on the analysis of 105 scientific sources, examines the advantages of these drugs, describes promising biological control agents that can be included in their composition, namely endophytic (colonize plant tissues) and extremophilic (survive in aggressive environmental conditions) microorganisms. The use of endophytic microorganisms in the fight against infectious diseases of plants is promising due to their ability to have a direct impact on the growth of crops and their induced resistance. The positive effect associated with the use of extremophilic microorganisms is associated with the universality of their use, namely the ability to maintain efficiency in various soil and climatic conditions.
