Mycosilver Nanoparticles: Synthesis, Characterization and its Efficacy against Plant Pathogenic Fungi
- 6 Downloads
The fungicides used to control plant pathogenic fungi not only kill the fungi but also affect other flora and fauna in the field. To preserve beneficial flora, novel strategies and alternative approaches should be identified. Bio-pesticides are used as an alternative to chemical fungicides. The development of nanotechnology-based fungicides and pesticides are considered as promising alternatives to preserve the biota. At the global level, researchers are working on nanoemulsion and nanofungicides to control plant pathogenic fungi; however, farmers are unaware about these nano-based fungicides. Metal nanoparticles can act as potential fungicides when compared to the conventional chemical fungicides. Hence, our current study is based on utilization of the myco-nanoparticles synthesized from endophytic fungi isolated from Solanum nigrum. The mycosilver nanoparticles are characterized by SEM, TEM and EDAX analysis. The results of the study exhibited the silver nanoparticles were of different morphological shapes including spherical, cylindrical and loosely agglomerated with an average size of 2–50 nm. Further, the plant pathogenic fungi including Fusarium graminearum, Fusarium udum, Rhizoctonia solani and Aspergillus niger were treated with mycosilver nanoparticles to test the efficacy to control plant pathogens, and showed broad spectrum antifungal activity against the phytopathogens by inhibiting the radial growth.
