Abstract:
The green method of nanoparticle synthesis, which is an eco-friendly way to synthesize nanoparticles was employed to synthesis zinc oxide nanoparticles using mustard seed extracts as reducing agents, and it was tested against the red rot pathogen Colletotrichum falcatum and biocontrol agent Trichoderma harzianum. Mustard seed-based ZnNPs (MS-ZnNPs) at five different concentrations (1, 2, 5, 10 and 15 mM) and precursor zinc nitrate at 15 mM were tested against C. falcatum and T. harzianum by dual culture assay. MS-ZnNPs showed maximum mycelial growth inhibition of C. falcatumat at 1 mM (76.1%), followed by 2 mM (67.1%) concentration. Whereas T. harzianum was not inhibited by synthesized Zinc nanoparticles at all tested concentrations.
