Destructive Effect of Silver Nanoparticles on Biocontrol Agent Fungi Trichoderma viride and T. harzianum
Journal Title: Caspian Journal of Applied Sciences Research - Year 2012, Vol 1, Issue 12
Abstract
Trichoderma spp. serves as biocontrol and growth promoting agents for many crop plants due to their antagonistic properties against plant pathogens. Nanoparticles have become of an interest relatively recently, mostly because of their possible use in diverse technologies. In this research we have investigated the role of silver nanoparticles on growth rate of two biocontrol agent species of Trichoderma viride and T. harzianum by measuring the diameter of colonies of fungi on potato dextrose agar and the dry weight of mycelia culture medium. In this test in order to determine the minimum inhibitory concentration, 25, 50, 100 and 150 ppm of silver nanoparticles were used. General Regression Analysis was used to determine both the time and concentration variable and the possible interactions. The results showed that silver nanoparticles caused inhibited the growth of the two species of fungi. In this paper we suggest that silver nanoparticles, because of the harmful effects on environment, should be used less.
