Nano-Particles as Management Tool against the Plant Pathogens

Sonia Yaseen

Nanotechnology is the one of most important and fascinating technology. This technology is progressing rapidly in sciences. The only purpose of this technology is that it has a potential to make many discipline which belong to sciences to make them modernized. It has also potential to make other technologies modernize which belong to medicine and agriculture. There are some reasons such as due to some plant pests and many pathogens causes loss of crops which is 20-40% this 20-40% loss of crops are lost every year due to these plant pest and pathogen attacks. Some toxic pesticides which are predominantly depends on the existing plant disease management these plant disease management depends on these toxic pesticides are very harmful for human life and to the environment where they live. Nanoparticles are basically existing as metalloids, metallic oxides, nonmetals, and carbon nano materials, and as functionalized, dendrimers, liposomes. The use of them as a bactericides/fungicides and its Nanoparticle have made them enable the only reason of their enabling them is their small size, large surface area and its high reactivity this make them enable to use. There are different number of Nano particles. In which NPs of single element and carbon nanomaterials which are effecting many plant pathogen and diseases. Ag, Cu and Zn are the only which have received much more attention. Some NPs that act directly as antimicrobial/fungicidal agents, while some of them function as more in altering the host as a nutritional status that thus plays a role for activating the plant defense mechanisms. It has been reported that in past few decades this “Nano technology” has excessively grown in phytopathology very exponentially. Some Nanomaterials which are integrated into strategies which are involve in plant diseases management strategies and some diagnostics and as a molecular tool. These are used in disease diagnosis, pathogen detection, and residual analysis that may have become much more precise, and quick with the use of nanotechnology. Nanotechnology could sustainably can mitigate that can face, many challenges that are included in disease management which can be done by reducing chemical inputs, and by use of promoting rapid detection of pathogens. Thus it was observed from the study, that all the nanoparticles are of different concentration that can bring about significant change which is by, inhibition in the germination of the spores
