Myco-silver nanoparticles synthesized using beauveria bassiana and metarhizium brunneum as a smart pest control

Abstract EN

Nanotechnology has recently been considered as a modern potential tool for crop protection at the nanoscale level.

biosynthesis of silver nanoparticles by using the entomopathogenic fungi, beauveria bassiana (bb) and metarhizium brunneum (mb) is as an eco-friendly and cost effective production system.

the produced nanoparticles revealed a brownish color that is characteristic for silver nanoparticles.

bb-synthesized agnps and mb-synthesized agnps were produced at various concentrations and characterized by uv-vis spectrophotometer and dynamic light scattering (dls).

the variation of hydrodynamic diameter (dh) of silver particles at various concentration of culture in conjunction with uv-vis spectra showed that production of agnps was maximized when using 15% of culture for both fungi and the size of particles was around 87 nm for both.

the efficacy of bb-synthesized agnps and mb-synthesized agnps against the two-spotted spider mite, tetranychus urticae koch (acari: tetranychidae) were tested.

results demonstrated that the treatments of either bb- or mb-synthesized agnps were found to be highly significantly virulent toward newly emerged adult female of t.

urticae.
