Abstract

Phytotoxicity is an important aspects of nanoparticles in relation to the environment and plants. Here, we report on the effects of biologically synthesized silver nanoparticles (Ag NPs) from Trichoderma asperellum on the development of Mustard, Chili, and French bean. Four toxicity indicators (seed germination, root and shoot length Chlorophyll content and Lipid peroxidation) were quantified following exposure to each nanoparticle at a concentrationof 1000ppm, 500ppm, 100ppm, 50ppm, 20ppm, 10ppm, 7ppm, 5ppm, 3ppm, 1ppm and carbendazim @0.3%. Results showed that silver nanoparticles at a concentration of 100 ppm and 50ppm effective in increasing all the growth parameters of the crops as compared to other concentration and carbendazim whereas it showed detrimental effects at a concentration of 1000ppm.
