“…Although molybdenum is a micronutrient for plants, the application of nano-MoO 3 (via foliar or soil) as micronutrient and/or promotor of plant growth have been limited. ,, Osman et al (2020) reported that nano-MoO 3 as foliar micronutrient decreased the quality and quantity of dry bean plants, but increased the productivity of common bean plants compared to molybdenum salt at (10–40 mg/L) . Conversely, a combination of microbial preparation and a colloidal suspension of molybdenum nanoparticles applied via soil at 8 mg/L to a Cicer arietinum L. stimulated the nodule formation per plant by four times .…”

Knowledge of dissolution, aggregation, and stability of nanoagrochemicals in root exudates (RE) and soil leachate will contribute to improving delivery mechanisms, transport in plants, and bioavailability. We characterized aggregation, stability, and dissolution of four nanoparticles (NPs) in soybean RE and soil leachate: nano-CeO 2 , nano-Mn 3 O 4 , nano-Cu(OH) 2 , and nano-MoO 3 . Aggregation differed considerably in different media. In RE, nano-Cu(OH) 2 , and nano-MoO 3 increased their aggregate size for 5 days; their mean sizes increased from 518 ± 43 nm to 938 ± 32 nm, and from 372 ± 14 nm to 690 ± 65 nm, respectively. Conversely, nano-CeO 2 and nano-Mn 3 O 4 disaggregated in RE with time, decreasing from 289 ± 5 nm to 129 ± 10 nm, and from 761 ± 58 nm to 143 ± 18 nm, respectively. Organic acids in RE and soil leachate can be adsorbed onto particle surfaces, influencing aggregation. Charge of the four NPs was negative in contact with RE and soil leachate, due to organic matter present in RE and soil leachate. Dissolution in RE after 6 days was 38%, 1.2%, 0.5%, and <0.1% of the elemental content of MoO 3 , Cu(OH) 2 , Mn 3 O 4 , and CeO 2 NPs. Thus, the bioavailability and efficiency of delivery of the NPs or their active ingredients will be substantially modified soon after they are in contact with RE or soil leachate.

“…The seeds of CB were sown in clay soil at 120 kg/ha in the first week of March in El-Monifia governorate, Egypt, during two seasons, 2018 and 2019. After 20 days of planting seeds, the plants were sprayed with MoO 3 -NPs at a concentration of 0, 10, 20, 30, and 40 ppm, as previously reported 27 .…”

Nanotechnologies has been used to introduce several beneficial tools in the agricultural field. Herein, the effect of molybdenum oxide nanoparticles (MoO3-NPs) was investigated by evaluating the hematological, biochemical, and histopathological parameters in rats orally exposed to MoO3-NPs or fed common beans (CB) fertilized by MoO3-NPs. In the first study, 18 rats were randomly divided into 3 groups: G1 (control group) was given water orally, while G2 and G3 were administered 10 and 40 ppm MoO3-NPs by oral gavage tube, respectively. There was a significant increase in the levels of alanine aminotransferase (ALT), albumin, and total protein; however, there was a a significant decrease in body weight change (BWC), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), creatinine, creatine kinase–MB (CK-MB), thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), and testosterone levels in G3 compared to G1. In the second study, 24 rats were divided into 4 groups: the control (C) group was fed a balanced diet, and three groups were fed on a balanced diet plus 10% CB that was fertilized with 0, 10, and 40 ppm MoO3-NPs, resulting in nCB, CB10, and CB40 groups, respectively. This revealed a significant increase in BWC and total food intake (TFI) but a significant decrease in relative kidney weight in all the CB groups compared to the control group. In CB10 and CB40 groups ALT, LDH, TSH, FT3, and testosterone levels were significantly lower than the respective levels in the control group. We concluded that high doses of MoO3-NPs caused more side effects than low doses in both experiments.

“…The increase in the seed growth might be due to molybdenum, an important micronutrient for plant growth which is involved in several oxidation-reduction processes in plants. Accordingly, the NPs are proved to have positive effects in promotion of root and shoot formation, and also accumulation of plant biomass from seeds in most of the crops compared to the untreated one [38].…”

Herein we report the hydrothermal synthesis, characterization and biological applications of h-MoO3 and silver doped MoO3 nanoparticles (NPs). The phase formation of the synthesized NPs was identified using X-ray diffraction studies and vibrational spectral studies. The average crystallite size of the NPs tends to decrease as the dopant concentration increases. The surface morphology and the elemental composition of the nanoparticles were observed from SEM and EDAX analysis. The crystallite nature was obtained from HRTEM images. The band gap energies obtained from UV-DRS spectra for h-MoO3 (3.26 eV) were starting to decrease as the concentration of the dopant Ag increases (3.22-2.76eV). The antibacterial activity of the prepared nanoparticles was tested against some gram positive and gram negative bacterial strains viz., Staphylococcus aureus, Bacillus cereus and Citrobacter koseri and Pseudomonas aeruginosa respectively. Also their seed germination properties were studied on foxtail and finger millet seeds for a period of seven days.
