“…The well-documented potential antagonistic ability of these beneficial bacteria and fungi not only works against plant pathogens but also aids in plant growth through various mechanisms such as siderophore formation, root colonization, accumulation of secondary metabolites, uptake of beneficial plant nutrients, and enhanced plant defence against abiotic and biotic factors [ [28] , [29] , [30] ]. Potential BCAs work through signaling molecules to increase the production of cell wall degrading enzymes, the biosynthesis of valuable microbes, growth reducing secondary metabolites, antibiosis, and lignin deposition in the cell wall, suppress disease severity, and elevate induced resistance in crop plants [ 31 , 32 ]. Trichoderma spp.…”

Chemical pesticides are still used to control Moler disease on shallots. The impact has the potential to kill macro species as well as non-target bacteria. Several prior researches have shown that botanical pesticides can suppress plant-disturbing organisms, but data on their impact on beneficial microbes is still limited. Hence, the impact of applying jengkol peel to control the primary disease of shallots and its impact on non-target organisms in peatlands was investigated in this study. The study was carried out in Landasan Ulin, South Kalimantan, from April to November 2021. Treatments were t0 (negative control), t1 (positive control, fungicide), t2 (0.125 kg/ha jengkol peelpowder), t3 (0.25 kg/ha jengkol peelpowder), and t4 (0.375 kg/ha jengkol peeljengkol peel powder). The parameters observed were the intensity of moler disease, the components of shallot production, species diversity, species richness, the evenness of microbial species, and the dominance index. The results showed that the application of jengko lpeel powder could suppress the attack of moler disease on shallots. Microbial diversity in shallot plantations treated with botanical pesticides and those not treated with botanical pesticides was similar, in the moderate range, as in shallot plantations treated with chemical pesticides. The species richness index, dominance index, and balance index had low-status values. The types of microbes found were Trichoderma sp., Aspergillus sp., Fusarium sp., Mucor sp., Aeromonas sp., Corynebacterium sp., Enterobacter sp. Sphingomonas sp., and Penicillium sp. The microbial population was affected by pesticide application. Plants that were not applied with botanical pesticides or chemical pesticides had fewer microbes. The application of botanical pesticides produced various impacts, the higher the dose, the lower the microbes in the onion rhizosphere.

Prospect and Challenges for Sustainable Management of Climate Change-Associated Stresses to Soil and Plant Health by Beneficial Rhizobacteria

et al. 2021

Climate change imposes biotic and abiotic stresses on soil and plant health all across the planet. Beneficial rhizobacterial genera, such as Bacillus, Pseudomonas, Paraburkholderia, Rhizobium, Serratia, and others, are gaining popularity due to their ability to provide simultaneous nutrition and protection of plants in adverse climatic conditions. Plant growth-promoting rhizobacteria are known to boost soil and plant health through a variety of direct and indirect mechanisms. However, various issues limit the wider commercialization of bacterial biostimulants, such as variable performance in different environmental conditions, poor shelf-life, application challenges, and our poor understanding on complex mechanisms of their interactions with plants and environment. This study focused on detecting the most recent findings on the improvement of plant and soil health under a stressful environment by the application of beneficial rhizobacteria. For a critical and systematic review story, we conducted a non-exhaustive but rigorous literature survey to assemble the most relevant literature (sorting of a total of 236 out of 300 articles produced from the search). In addition, a critical discussion deciphering the major challenges for the commercialization of these bioagents as biofertilizer, biostimulants, and biopesticides was undertaken to unlock the prospective research avenues and wider application of these natural resources. The advancement of biotechnological tools may help to enhance the sustainable use of bacterial biostimulants in agriculture. The perspective of biostimulants is also systematically evaluated for a better understanding of the molecular crosstalk between plants and beneficial bacteria in the changing climate towards sustainable soil and plant health.
