“…The examined NPs displayed potential fungal effect against S. sclerotoirum. These findings are in accordance with that previously obtained [30][31][32], where NPs are in effective as nanocides against plant fungal pathogens as stated in species, mung bean (Phaseolus radiatus) and wheat (Triticum aestivum). Management of fungal diseases in plant nurseries is economically important and of environmental concern, to avoid the introduction and spread of diseases.…”

Antifungal efficacy for some oxides of metallic nanoparticles (NPs) e.g. magnesium (MgO), copper (CuO), silicon (SiO2) and zinc (ZnO) was evaluated against fungi, Sclerotinia sclerotioum on bean plants under different conditions. The examined NPs exhibited significant effect on hyphal morphology and fungal linear growth under field trail in the following order: MgONPs> SiO2NPs> ZnONPs> CuONPs compared with control group. However under storage condition, the disease severity along NPs-treated bean pods were in the order: MgONPs> SiO2NPs> ZnONPs> CuONPs compared with infected control which did not exceed 30.23% and non-infected (14.68%). Bean pods treated with NPs showed significantly increase in chlorophyll content, total phenols, and ascorbic acid compared with non-infected pods during storage period for 4 weeks. The examined NPs exhibited positive accumulation in pods tissues, except MgO was lower than non-infected group. The present findings may display the potential effect metal oxides in agricultural sector need more studies to achieve their adverse effects on consumers and environmental impacts.

Eugenol oil nanoemulsion: antifungal activity against Fusarium oxysporum f. sp. vasinfectum and phytotoxicity on cottonseeds

The current research deals with the formulation and characterization of bio-based oil-in-water nanoemulsion. The formulated eugenol oil nanoemulsion was characterized by dynamic light scattering, stability test, transmission electron microscopy and thin layer chromatography. The nanoemulsion droplets were found to have a Z-average diameter of 80 nm and TEM study reveals the spherical shape of eugenol oil nanoemulsion (EON). The size of the nanoemulsion was found to be physically stable up to more than 1-month when it was kept at room temperature (25°C). The TEM micrograph showed that the EON was spherical in shape and moderately mono or di-dispersed and was in the range of 50-110 nm. Three concentrations of the nanoformulation were used to evalute the anti-fusarium activity both in vitro and in vivo experiments. SDS-PAGE results of total protein from the Fusarium oxysporum f. sp. vasinfectum (FOV) isolate before and after treatment with eugenol oil nanoemulsion indicate that the content of extra cellular soluble small molecular proteins decreased significantly in EON-treated fungus. Light micrographs of mycelia and spores treated with EON showed the disruption of the fungal structures. The analysis of variance (ANOVA) for Fusarium wilt incidence indicated highly significant (p = 0.000) effects of concentration, genotype, and their interaction. The difference in wilt incidence between concentrations and control was not the same for each genotype, that is, the genotypes responded differently to concentrations. Effects of three EON concentration on germination percentage, and radicle length, were determined in the laboratory. One very interesting finding in the current study is that cotton genotypes was the most important factors in determining wilt incidence as it accounted for 93.18 % of the explained (model) variation. In vitro experiments were conducted to evaluate the potential phytotoxic effect of three EON concentrations. Concentration, genotype and concentration x genotype interaction were all highly significant sources of variation in seed germination; however, interaction was the first in importance as a source of variation followed by the concentration, while genotype was the least important source of variation. These results suggest the potential use of eugenol oil nanoemulsion for protecting seedcotton from Fusarium wilt infection.

Nanotechnology can offer green and eco-friendly alternatives for plant disease management. Apart from being eco-friendly, fungi are used as bio-manufacturing units, which will provide an added benefit in being easy to use, as compared to other microbes. The non-pathogenic nature of some fungal species in combination with the simplicity of production and handling will improve the mass production of silver nanoparticles. Recently, a diverse range of fungi have been screened for their ability to create silver nanoparticles. Mycosynthesis of gold, silver, gold–silver alloy, selenium, tellurium, platinum, palladium, silica, titania, zirconia, quantum dots, usnic acid, magnetite, cadmium telluride and uraninite nanoparticles has also been reported by various researchers. Nanotechnological application in plant pathology is still in the early stages. For example, nanofungicides, nanopesticides and nanoherbicides are being used extensively in agriculture practices. Remote activation and monitoring of intelligent nano-delivery systems can assist agricultural growers of the future to minimize fungicides and pesticides use. Nanoparticle-mediated gene transfer would be useful for improvement of crops resistant to pathogens and pest. This review critically assesses the role of fungi in the synthesis of nanoparticles, the mechanism involved in the synthesis, the effect of different factors on the reduction of metal ions in developing low-cost techniques for the synthesis and recovery of nanoparticles. Moreover, the application of nanoparticles in plant disease control, antimicrobial mechanisms, and nanotoxicity on plant ecosystem and soil microbial communities has also been discussed in detail.
