“…The fungistatic effect of AgNPs towards economically important plant pathogens has been demonstrated in many studies (Cioffi et al 2004;Park et al 2006;Gajbhiye et al 2009;Jo et al 2009;Min et al 2009). The present study confirmed the previously observed effect of AgNPs produced by the high-voltage arc discharge method on Fc, demonstrating in the fungistatic effect and the modification of pathogen metabolism occurring at low concentrations of Ag (Kasprowicz et al 2010.…”

“…One of the areas where these properties could be used is plant protection. In previous studies the strong fungistatic character of AgNPs, produced by high-voltage arc discharge method, against Fusarium culmorum (Fc) was reported (Kasprowicz et al 2010). The overproduction of secondary metabolites from the group of naphthoquinones after contact with AgNPs was also observed .…”

The purpose of this study was to examine the effect of silver nanoparticles (AgNPs) produced using the high-voltage arc discharge method on the growth and metabolism of common wheat seedlings. Additionally, a simultaneous assessment of the AgNP-induced reduction in seedling infection by Fusarium culmorum (Fc) was performed. AgNP-and Fc-treated seedlings indicated that both factors considerably inhibited their growth. A significant Fc-induced reduction in seedling blight was observed following treatment with AgNPs; however, treatment with nanoparticles was also accompanied by a serious disintegration of the cell membranes of roots. Moreover, treatment with AgNPs increased the quantum efficiency of energy trapping in the PSII reaction centre (F v /F m ) with a simultaneous decrease in energy dissipation in the form of heat. Induction of photosynthesis in the presence of AgNPs did not affect height but was reflected in higher total dry weight. Moreover, analysis of antioxidant enzyme activity typical for the stress response indicated the toxicity of AgNPs treatment compared to Fc treatment. Seedlings exposed to AgNP activity demonstrated accumulation of Ag in roots and its translocation to aerial parts, while the pathogen reduced both accumulation and translocation of this element.

“…The tested nanoparticles showed significant effect against B. fabae and A. alternata relative to control. The results agree with the findings of Kasprowicz et al [55] who reported that silver nanoparticles have been used to prevent some plant pathogens. Derbalah et al [7] found that the silver nanoparticles have antimicrobial activity against B. fabae.…”

Faba bean (Vicia fabae L.) is one of the most economic legume crops in Egypt. The antifungal effects of different concentrations of Chitosan and silver nanoparticles (20 ppm, 40 ppm, 60 ppm, 80 ppm and 100 ppm) were studied against aggressive isolates of Botrytis fabae and Alternaria alternata causing chocolate spot disease and Alternaria leaf spot disease respectively. Under laboratory conditions, the application of five concentrations of Chitosan nanoparticles and silver nanoparticles to the cultures of B. fabae and A. alternata showed significant inhibition of mycelial growth. Number of spores/ml decreased with increasing of nanoparticle concentration. Mycelial weight of fungal pathogens also decreased. The lesion growth was suppressed by increasing in the concentration of nanoparticles with significantly different relative to control using detached leaf test. Under greenhouse conditions, chitosan and silver nanoparticles were sprayed in concentrations 60 ppm, 80 ppm, and 100 ppm on faba bean plants. The tested nanoparticles showed significant effect against B. fabae and A. alternata relative to control. The obtained results indicated that the highest reduction of chocolate spot severity was obtained with treatment by 100 ppm of silver nanoparticles (52.94%) followed by chitosan nanoparticles 80 ppm (50.59%). While the application of 100 ppm of chitosan nanoparticles was highly efficient against Alternaria leaf spot where the reduction in disease severity (67.13%) followed by 100 ppm silver nanoparticles which caused reduction rate (61.5%). The obtained results indicated the possibility of using chitosan and silver nanoparticles as a substance in the manufacturing of fungicides to minimize the impact of chocolate spot and Alternaria leaf spot diseases in faba bean. However, further experimental trials under field conditions and safety evaluation studies are needed before the nanoparticles types and concentrations can be used as potential antifungal agents.

The effect of silver nanoparticles on plant pathogenic spores of Fusarium culmorum was studied by Kasprowicz et al [12]. The silver nanoparticles also found to exhibit antifungal activity against Fusarium oxysporum [13].…”
