In vitro evaluation of biosynthesized silver nanoparticles (ag nps) against Fusarium oxysporum f. Sp. Capsici causing wilt of chilli

Abstract

Efficacy of biosynthesized silver nanoparticle at different concentration (250 ppm, 500 ppm and 750 ppm) was tested against Fusarium oxysporum f. sp. capsici causing wilt of chilli by poisoned food technique and the result showed that the Trichoderma harzianum silver nanoparticles @ 750 ppm was found most effective with least mycelial growth (20.23 mm) and numerically highest mycelial inhibition (77.52%), followed by T. harzianum silver nanoparticles @ 500 ppm (35.73 mm and 60.30%), T. harzianum silver nanoparticles @ 250 (46.30 mm and 48.55%), T. hamatum silver nanoparticles @ 750 ppm (46.96 mm and 47.82%), T. hamatum silver nanoparticles @ 500 ppm (58.16 mm and 35.37%) and Trichoderma asperellum silver nanoparticles @ 750 ppm (61.66 mm and 31.48%), respectively over control.
