“…Phosphorus can enhance drought and disease resistance in plants and promote their growth and development. A lack of phosphorus leads to a significant decrease in crop yield ( Elhaissoufi et al, 2021 ). The results of this study showed that the AP content and ACP activity of ginseng rhizosphere soil treated with MA were significantly higher than those in other treatments.…”

Plant-associated microbes play important roles in plant health and disease. Mortierella is often found in the plant rhizosphere, and its possible functions are not well known, especially in medical plants. Mortierella alpina isolated from ginseng soil was used to investigate its effects on plant disease. The promoting properties and interactions with rhizospheric microorganisms were investigated in a medium. Further, a pot experiment was conducted to explore its effects on ginseng root rot disease. Physicochemical properties, high-throughput sequencing, network co-occurrence, distance-based redundancy analysis (db-RDA), and correlation analysis were used to evaluate their effects on the root rot pathogen. The results showed that Mortierella alpina YW25 had a high indoleacetic acid production capacity, and the maximum yield was 141.37 mg/L at 4 days. The growth of M. alpina YW25 was inhibited by some probiotics (Bacillus, Streptomyces, Brevibacterium, Trichoderma, etc.) and potential pathogens (Cladosporium, Aspergillus, etc.), but it did not show sensitivity to the soil-borne pathogen Fusarium oxysporum. Pot experiments showed that M. alpina could significantly alleviate the diseases caused by F. oxysporum, and increased the available nitrogen and phosphorus content in rhizosphere soil. In addition, it enhanced the activities of soil sucrase and acid phosphatase. High-throughput results showed that the inoculation of M. alpina with F. oxysporum changed the microbial community structure of ginseng, stimulated the plant to recruit more plant growth-promoting bacteria, and constructed a more stable microbial network of ginseng root. In this study, we found and proved the potential of M. alpina as a biocontrol agent against F. oxysporum, providing a new idea for controlling soil-borne diseases of ginseng by regulating rhizosphere microorganisms.

“…However, there are limitations on how well these management strategies can improve P use efficiency. As an alternative, the use of soil microbes, which can promote P solubility, use efficiency, and crop productivity, has been suggested (Elhaissoufi et al, 2021). Inoculation with beneficial microorganisms, as a form of biofertilizer, could then be used to replace the high inputs of chemical fertilizers in crop production (Billah et al, 2019;Kennedy et al, 2004).…”

“…In this regard, beneficial microbes such as phosphate-solubilizing bacteria (PSB), usually found in the rhizosphere of most plants, are attracting particular attention because of their reported advantages for alkaline calcareous soils (Elhaissoufi et al, 2021;Jilani et al, 2021). The soils in Pakistan are calcareous in nature and alkaline in reaction, which causes unavailability of P and N for plant uptake and growth promotion (Rahim et al, 2020).…”

“…Phosphorus is an important macronutrient which is directly involved in nucleic acids, cells division and growth of new tissues, which also control or regulate protein synthesis and energy transfer [5]. Lack of phosphate can result in significant reductions (up to 15%) of crop yield [5].…”

Aim: The study was aimed to determine the toxicity of paraquat dichloride and lambda-cyhalothrin on phosphate solubilizing bacteria, Pantoa dispersa in aquatic ecosystems. Study Design: This study employs randomized block design, statistical analysis of the data and interpretation. Place and Duration of the Study: Soil sample was collected from the root nodules of leguminous plants in a sterile polythene bag from the Elele, in Etche L.G.A, Rivers State. The fresh water sample was collected from Bane town in Khana L.G.A, brackish water sample was collected from Choba river in Obio/Akpor L.G.A while the marine water was collected from Bonny River of Bonny L.G.A., all of Rivers State, Nigeria. The samples were collected aseptically and transported in an ice-pack immediately to the Rivers State University, Microbiology laboratory for analysis. The study lasted for three months. Methodology: The bacterium, Pantoa dispersa was isolated and identified based on conventional and molecular characterization from water and soil samples. Different concentrations (3.13%, 6.25, 12.50, 25.00%, 50.00% and 75.00%) and the control (0%) of the herbicide (paraquat dichloride) and insecticide, Lambda-cyhalothrin were prepared using fresh, brackish and marine water samples and 10ml of the test organism, Pantoa dispersa was introduced and the survival count was determined at 0, 4hr, 8hr, 12hr and 24hr. The Mean Lethal Concentration (LC50) of the insecticide and herbicide on Pantoa dispersa in the three aquatic ecosystem was determined. Results: The LC50 of the herbicide (Paraquat dichloride) was recorded as 15.8% in brackish water, 17.37% in fresh water and 27.44% in marine water. While the LC50 of the insecticide, Lambda-cyhalothrin to Pantoa dispersa was 26.84% in fresh water, 27.26% in brackish water and 32.33% in marine water. Conclusion: From the study, the herbicide, Paraquat dichloride was more toxic in the three aquatic ecosystems compared to the insecticide, Lambda-cyhalothrin. The use of these agrochemicals should be monitored as they result in the mortality of beneficial soil bacteria like Pantoa dispersa which is phosphate solubilizing bacteria in aquatic ecosystems.
