Nanotechnology, which has become an important area of science, has caused an enormous developmental
revolution in many fields. In the last two decades researchers have focused on overcoming the obstacles encountered during the
preparation of nanoparticles. This article highlights the nanotechnology, along with a brief description of the manufacturing,
concepts and activities of nanoparticles as alternative pesticides against plant pathogens, some methods for evaluation of
nanoparticles against phytopathogens and , and explains the importance of some common nanoparticle types used
in agricultural applications and plant pathology.
