Background: Biogenic metallic and oxide metal nanoparticles have potential as alternatives for several current problems in agriculture, such as the control of caterpillars which cause huge losses in the production of important crops. In the present study, capped and uncapped silver, iron oxide and titanium dioxide nanoparticles were synthesized from the filtrate of Beauveria bassiana and evaluated in regard to physico-chemical characteristics, capping composition, cytotoxicity, genotoxicity and biological activity on Helicoverpa armigera and Spodoptera frugiperda caterpillars.
Results: A difference in the physico-chemical parameters of the capped and uncapped nanoparticles was observed, with larger aggregation and lower stability of the uncapped.
Article Synopsis
- * Successful synthesis resulted in increased mycelial growth compared to traditional methods, with the nanoparticles demonstrating inhibitory effects against the phytopathogen Sclerotinia sclerotiorum and showing strong chitinolytic activity.
- * The nanoparticles were non-toxic to human cells with protective effects, did not harm beneficial agricultural microorganisms, and did not negatively affect soybean plants, supporting their potential in sustainable agriculture.
