- Abstract
There have been impressive developments in the field of nanotechnology in the recent past, with numerous methodologies formulated to synthesize bionanoparticles using plants. Currently, there is a growing need to develop environmentally benign nanoparticles synthesis processes that do not use toxic chemicals in the synthesis protocol. We report the use of marine algae Padina pavonica (Linn.) thallus broth in the extra cellular synthesis for bio-silver nanoparticles. The biosynthesized silver nanoparticles were characterized with UV-vis Spectroscopy, FTIR, XRD, SEM and TEM. The thallus extract as well as silver-based nanoparticles of marine alga, P. pavonica (Linn.) were tested against two important pathogens of cotton. Fusarium wilts (Fusarium oxysporum f.sp. vasinfectum) and bacterial leaf blight (Xanthomonas campestris pv malvacearum) are responsible for significant yield losses in cotton worldwide. The P. pavonica based silver nanoparticles inhibited the growth of the test pathogens (12.33±0.33 mm and 10.33±0.33 mm for F. oxysporum and X. campestris respectively). This novel highly stable spherical polydispersed bionanoparticle was synthesized using a simple environmental friendly green method, and can be used for the management of cotton phytopathogens.
