Myconanotechnology is a branch of science which deals with the study of nanoparticle synthesis by using fungi. Fungus mediated synthesis of nanoparticles is a reliable and ecofriendly technique. In the present work T.harzianum was used for the synthesis of silver nanoparticle.The synthesized nanoparticles were characterized using UV-Spectrophtometer, Transmission Electron Microscope (TEM) and Fourier Transform Infrared Spectroscopy (FTIR). Through TEM analysis shape and size of the synthesiszed nanoparticles was determined. The size of the synthesised nanoparticles was 12 nm. The synthesiszed nanoparticles were tested in glass house conditions against the Fusarium wilt of tomato. Nanoparticle treated plants showed promotory effect on the all tested paparmeters (germination, plant height, root length, total yield and root dry weight) as compared to control and Trichoderm formulation treated plants.
