“…FND3, and Paracoccus sp. YM3 efficiently removed 80% methomyl within 7 days as compared to the 40-day degradation period of Flavobacterium and Alcaligenes [76,77,85,87]. Interestingly, some bacteria can degrade methomyl as well as other pesticides, such as aldicarb, oxamyl, fenamiphos, and Imidacloprid [75,79,84,86].…”

Methomyl is a broad-spectrum oxime carbamate commonly used to control arthropods, nematodes, flies, and crop pests. However, extensive use of this pesticide in agricultural practices has led to environmental toxicity and human health issues. Oxidation, incineration, adsorption, and microbial degradation methods have been developed to remove insecticidal residues from soil/water environments. Compared with physicochemical methods, biodegradation is considered to be a cost-effective and ecofriendly approach to the removal of pesticide residues. Therefore, micro-organisms have become a key component of the degradation and detoxification of methomyl through catabolic pathways and genetic determinants. Several species of methomyl-degrading bacteria have been isolated and characterized, including Paracoccus, Pseudomonas, Aminobacter, Flavobacterium, Alcaligenes, Bacillus, Serratia, Novosphingobium, and Trametes. The degradation pathways of methomyl and the fate of several metabolites have been investigated. Further in-depth studies based on molecular biology and genetics are needed to elaborate their role in the evolution of novel catabolic pathways and the microbial degradation of methomyl. In this review, we highlight the mechanism of microbial degradation of methomyl along with metabolic pathways and genes/enzymes of different genera.

“…Crop rotation, cultural practices, or use of disease-resistant varieties are commonly employed for the management of soil borne pathogens (Roy et al 2018), but these methods are not satisfactory for control of phytopathogens. Although, chemical pesticides are e cient way to control fungal pathogens and enhance crop productivity, but their application is being increasingly limited or banned due to negative impact on the soil fertility, microbial diversity, and ecosystem and causes toxicity to animals and humans (Alori and Babalola 2018;Prakash, and Arora, 2019).…”

Plant growth promoting rhizobacteria offer an effective and eco-sustainable solution to protect crops against phytopathogens. In the present study, Bacillus safensis STJP (NAIMCC-B-02323) from the rhizospheric soil of Stevia rebaudiana showed strong biocontrol activity against phytopathogen, Alternaria alternata. B. safensis STJP produced antifungal volatile organic compounds (AVOC). In the presence of AVOC, there was no conidia germination, mycelium growth was inhibited, and hyphae ruptured as observed by scanning electron microscopy (SEM). When mycelium of the fungus from bacterial treated plate was transferred into fresh potato dextrose agar plate, A. alternata could not grow. Extracted AVOC from B. safensis STJP were identified by thin-layer chromatography (TLC), fourier-transform-infrared spectroscopy (FT-IR) and gas-chromatography-mass spectrometry (GC-MS). In total 25 antifungal metabolites were identified by GC-MS analysis having alcohol, alkane, phenol, alkyl halide and aromatic compounds. Five compounds (phenol, 2,4-bis (1,1-dimethylethyl)-, 3-hexadecanol, pyrrolo(1,2-a)pyrazine-1,4-dione, 5,10-diethoxy-2,3,7,8-tetrahydro-1H,6H-dipyrrolo(1,2-a:1',2'-d)pyrazine and hexadecanoic acid) completely inhibited the mycelium growth, controlling spore formation and conidia germination of A. alternata. This study concluded that AVOC producing B. safensis can be used as a green-fungicide against A. alternata. Bacterial metabolites could pave the way for the development of next generation biopesticide. This can be a reliable technology to enhance the quality and reliability of biopesticides.

The present study demonstrates the interactions of fungicide-tolerant symbiotic bacteria Mesorhizobium ciceri with Cicer arietinum-kitazin (KITZ) in greenhouse conditions. Under both in vitro and soil systems, KITZ imparted deleterious impacts on plants as a function of dose. The three-time KITZ dose detrimentally and maximally reduced germination efficiency, vigor index, dry matter production, symbiosis, leaf pigments and seed attributes of C. arietinum. KITZ- induced morphological alterations in root tips, oxidative damage and cell death in root cells of C. arietinum were shown by SEM. M. ciceri tolerated up to 2400 µgmL− 1 of KITZ, synthesized considerable amounts of bioactive molecules including indole-3-acetic-acid (IAA), 1-aminocyclopropane 1-carboxylate (ACC) deaminase, siderophores, exopolysaccharides (EPS), HCN and ammonia, and solubilised inorganic phosphate even in fungicide-stressed media. Following application to soil, M. ciceri improved performance of C. arietinum and enhanced dry biomass production, yield, symbiosis and leaf pigments even in a fungicide-polluted environment. At 92 µgKITZkg− 1 soil, M. ciceri maximally and significantly (p ≤ 0.05) augmented whole plant length by 41%, total dry biomass by 18%, carotenoid content by 9%, LHb content by 21%, root N by 9%, shoot P by 11% and pod yield by 15%. Additionally, M. ciceri was associated with decreased levels of stressor molecules (proline and MDA) and antioxidant defence enzymes (APX, GPX, CAT and POD) of C. arietinum plants when inoculated in soil. The symbiotic strain effectively colonized the plant rhizosphere/rhizoplane. In pesticide- contaminated soils, inoculation of M. ciceri may serve as an excellent strategy for augmenting C. arietinum productivity.
