Silver nanoparticles (AgNPs) are widely used in industry due to their anti-microbial properties. Despite of its beneficial, they may potentially affect the activity of beneficial soil microorganisms. Trichoderma harzianum was used in this to investigate the effect of AgNPs on beneficial soil fungi. Colony diameter and spore production of T. harzianum were observed in the presence of three levels of AgNPs (200, 600, 1000 mg L −1 ) in growth media. The results showed that the application of AgNPs at high levels reduced colony diameter and spore production of the tested fungi. The findings indicate that AgNPs have the potential to damage beneficial soil fungi.
