“…However, at a higher 3,000 μg/ml (T-4) CBZM concentration, there was no P-solubilizing activity observed. The results are in contrast with other findings of earlier research where Pseudomonas fluorescens showed a declining trend of TCP solubilization under pesticide treatment ( Al-Enazi et al, 2022 ).…”

“…Results showed that the amount of ACCD was reduced by 38.9, 64.1, and a maximum of 92.3 at 1,000 μg/ml (T-2), 2,000 μg/ml (T-3), and 3,000 μg/ml (T-4) fungicide levels, respectively, over unstressed control (T-1). Several studies ( Syed et al, 2021 ; Al-Enazi et al, 2022 ) have found that fungicides and heavy metals reduce the ACC deaminase activity of soil bacteria in a similar way.…”

“…The great metabolic flexibility of the bacterial isolate allows them to inhabit variable environments such as those reported in the present study. Similarly, by referring to Bergey’s Manual of Systematic Bacteriology Al-Enazi et al (2022) characterized pesticide-tolerant Pseudomonas sp. from the rhizosphere soil of Vigna radiata (L.).…”

“…Any loss of soil microbial flora due to fungicide application could result in deteriorating soil health and lead to reduced field productivity. The repetitive use of fungicides or pesticides increases their persistence in the soil, which leads to affected microbial growth and performance ( Gill and Garg, 2014 ; Al-Enazi et al, 2022 ). Reports are available highlighting the dose dependent effects of fungicides on plant growth promoting rhizobacteria (PGPR), i.e., with the increase of dose adverse effects of fungicide/pesticide on PGPR ( Yang et al, 2011 ; Mundi et al, 2020 ).…”

Agrochemicals are consistently used in agricultural practices to protect plants from pathogens and ensure high crop production. However, their overconsumption and irregular use cause adverse impacts on soil flora and non-target beneficial microorganisms, ultimately causing a hazard to the ecosystem. Taking this into account, the present study was conducted to determine the high dosage of fungicide (carbendazim: CBZM) effects on the rhizobacteria survival, plant growth promoting trait and reactive oxygen species (ROS) scavenging antioxidant enzyme system. Thus, a multifarious plant growth promoting rhizobacteria (PGPR) isolate, ANCB-12, was obtained from the sugarcane rhizosphere through an enrichment technique. The taxonomic position of the isolated rhizobacteria was confirmed through 16S rRNA gene sequencing analysis as Priestia megaterium ANCB-12 (accession no. ON878101). Results showed that increasing concentrations of fungicide showed adverse effects on rhizobacterial cell growth and survival. In addition, cell visualization under a confocal laser scanning microscope (CLSM) revealed more oxidative stress damage in the form of ROS generation and cell membrane permeability. Furthermore, the increasing dose of CBZM gradually decreased the plant growth promoting activities of the rhizobacteria ANCB-12. For example, CBZM at a maximum 3,000 μg/ml concentration decreases the indole acetic acid (IAA) production by 91.6%, ACC deaminase by 92.3%, and siderophore production by 94.1%, respectively. Similarly, higher dose of fungicide enhanced the ROS toxicity by significantly (p < 0.05) modulating the stress-related antioxidant enzymatic biomarkers in P. megaterium ANCB-12. At a maximum 3,000 μg/ml CBZM concentration, the activity of superoxide dismutase (SOD) declined by 82.3%, catalase (CAT) by 61.4%, glutathione peroxidase (GPX) by 76.1%, and glutathione reductase (GR) by 84.8%, respectively. The results of this study showed that higher doses of the fungicide carbendazim are toxic to the cells of plant-beneficial rhizobacteria. This suggests that a recommended dose of fungicide should be made to lessen its harmful effects.

“…Incorporating both isolates can be a practical approach for remediating fungicide-contaminated soil, as well as enhancing radish plant growth while reducing fungicide inputs. Enhazi [66] conducted a study to assess the efficacy of plant growth-promoting (PGP) rhizobacterial strains that are resistant to pesticide toxicity. The researchers isolated Pseudomonas sp.…”

Rhizosheric bacteria with several abilities related to plant growth and health have been denominated Plant Growth-Promoting Rhizobacteria (PGPR). PGPR promote plant growth through several modes of action, be it directly or indirectly. The benefits provided by these bacteria can include increased nutrient availability, phytohormone production, shoot and root development, protection against several phytopathogens, and reduced diseases. Additionally, PGPR can help plants to withstand abiotic stresses such as salinity and drought and produce enzymes that detoxify plants from heavy metals. PGPR have become an important strategy in sustainable agriculture due to the possibility of reducing synthetic fertilizers and pesticides, promoting plant growth and health, and enhancing soil quality. There are many studies related to PGPR in the literature. However, this review highlights the studies that used PGPR for sustainable production in a practical way, making it possible to reduce the use of fertilizers such as phosphorus and nitrogen and fungicides, and to improve nutrient uptake. This review addresses topics such as unconventional fertilizers, seed microbiome for rhizospheric colonization, rhizospheric microorganisms, nitrogen fixation for reducing chemical fertilizers, phosphorus solubilizing and mineralizing, and siderophore and phytohormone production for reducing the use of fungicides and pesticides for sustainable agriculture.

Unraveling the potential of pesticide-tolerant Pseudomonas sp. augmenting biological and physiological attributes of Vigna radiata (L.) under pesticide stress

Abstract: In the agricultural domain, chemical pesticides are repetitively and harshly used to kill harmful pests, but they often pose a serious threat to microbial diversity, soil fertility and agricultural output.
