Special Issue Information

Dear Colleagues,

This Special Issue is a continuation of our 2024 Special Issue titled "Microorganisms as Biocontrol Agents in Plant Pathology".

Welcome to the Special Issue “Microorganisms as Biocontrol Agents in Plant Pathology, 2nd Edition” of Microorganisms. Plant diseases occur in the entire crop production chain and are one of the greatest threats to the sustainable development of society, resulting in yield and economic losses. However, the intensive use of chemical fungicides to suppress the growth of plant pathogens has contributed to environmental pollution (e.g., long degradation periods), biodiversity losses, undesirable effects on human health (e.g., carcinogenicity) and the development of pathogen resistance. The most current strategies included in the United Nations 2030 Agenda (17 SDGs) aim at achieving food security and promoting sustainable agriculture. Thus, the application of biopesticides in place of synthetic chemicals creates a balance amongst economic productivity and environmental protection.

Moreover, microorganisms are well known as plant growth promoters, as biocontrol agents against plant pathogens and for their ability to produce secondary metabolites with antimicrobial activities. Therefore, the use of biocontrol microorganisms and applications of naturally sourced metabolites are alternative methods for the safe control of plant pathogens to assist in sustainable agriculture. In this regard, the development and contributions of novelties in this research field require up-to-date review papers.

In this Special Issue, we invite you to contribute any aspects related to the biological control of microorganisms. This may include, for instance, plant-growth-promoting bacteria or fungi, endophytes and/or epiphytes involved in plant tolerance to stressful factors, in the acquisition of limited nutrients or in the production of secondary metabolites with antimicrobial activities. The molecular aspects related to the interaction between plants and their microbial community, as well as the exploitation of omic approaches to reveal key genes/metabolites/proteins of biocontrol microorganisms, are also welcome.

Development of native microbial consortia is crucial for the sustainable management of plant diseases in modern agriculture. This study aimed to evaluate the antagonistic potential of various microbial isolates against Rhizoctonia bataticola, a significant soil-borne pathogen. A total of 480 bacteria, 283 fungi, and 150 actinomycetes were isolated and screened using in vitro dual plate assays. Among these, isolates 5F, 131B, 223B, and 236B demonstrated the highest antagonistic activity, with inhibition rates of 88.24%, 87.5%, 81.25%, and 81.25%, respectively. The selected isolates were further assessed for abiotic stress tolerance, revealing their ability to thrive under extreme conditions. Characterization of biocontrol and plant growth-promoting activities revealed the production of siderophores, hydrogen cyanide, ammonia, chitinase, and indole-3-acetic acid, along with the solubilization of zinc and phosphorus. Compatibility tests confirmed the potential of forming effective microbial consortia, which significantly reduced the percent disease index in cluster bean. The most effective consortium, comprising Trichoderma afroharzianum 5F, Pseudomonas fluorescens 131B, Bacillus licheniformis 223B, and Bacillus subtilis 236B, achieved a 76.5% disease control. Additionally, this consortium enhanced total phenol (92.1%), flavonoids (141.6%), and antioxidant defense enzyme activities including POX (188.5%), PPOX (116.3%), PAL (71.2%), and TAL (129.9%) in cluster bean plants over the infected control, leading to substantial improvements in systemic resistance of plants. This consortium also significantly enhanced plant height, fresh weight, dry weight, number of pods per plant, and seed yield over the infected control as well as mock control. This study underscores the potential of these robust microbial consortia as a sustainable and effective strategy for managing R. bataticola and enhancing crop productivity under extreme environmental conditions.
