Abstract

Abstract: Groundnut crop is an important oil seed crop, mostly affected by root rot complex fungal pathogens Aspergillus niger (Collar rot), Sclerotium rolfsii (Stem rot/Sclerotium wilt) and Macrophomina phaseolina (Dry root rot/dry wilt). Cell free culture filtrates of T. harzianum was used for the green synthesis of silver nanoparticles (AgNPs) and also measured by using Transmission Electron Microscopy. These synthesized nanoparticles were found in single or aggregated with round and uniform in shape and 10–25 nm in size. Biosynthesized silver nanoparticles (25, 50, 75, 100 ppm) were tested against pathogens revealed that T. harzianum Th3 exhibits effective mycelial growth control up to 60–65% against root rot complex pathogen of groundnut.
