Abstract:
Nanotechnology has application potential and prospects in plant pathology in many different aspects viz. direct application in foliage, seeds or soil for plant disease management along with accurate, reproducible, quantitative, reliable, specific, robust, and stable results. Extracellularly and intracellularly synthesis of NPs is carried out using microbes. Detection of plant pathogen plays an important role in successful management of many plant diseases, allowing the effective controlling of disease at various stages of disease development. By virtue of their small size, nanoparticles have exclusive chemical, photosensitive and electrical properties and offer improved surface-to-volume ratios. Nano particles finds application in regulation of pathogen concentration, its severity, rate of infection, and percentage of bacteria and fungi, viruses, actinomycetes and other pathogens. Nanoparticles causes induction of systemic resistance, reduction of cellular factors, inhibition of DNA replication, suppression of polymerase activity and lowering of infection rate. Emergence of nano particles has enormous concern in agriculture in relation to environment. Even though some of the nanoparticles have varied negative effect, which might lead to degradation of root membrane, remodeling agriculture and successful management of plant pathogens would not be possible without nanotechnology which directly reflects positively on the sustenance of food production and fulfil the increasing demands of food production in an efficient and cost-effective way. Moreover, nanotechnology plays important role in pathogen sensing and control and provides a remedy to the emerging agricultural challenges. Profound research studies, regarding the possible aspects of nanotechnology in plant pathology, is being carried out for exploring an economic, eco-friendly stabilized nanomaterials for effective management of plant diseases in the long run.
