A Soil nematode infecting plants are one of the most destructive parasites worldwide, it attacking plant root system and feed on the plant nutrients causing lose in the crop yield even plant death by developing galls and necrosis in the root system, lose its ability of absorb nutrients, water and die. The major issue concerning nematode damage to plants is the lack of effective chemical treatment methods, Public concern over the chemical Nematicides is not only their toxicity for health and environmental but also their loss of efficiency after prolonged use. Several control strategies alternative to chemical control that develops recently is production of natural Bio-Nano Nematicides as (green chemical) which act as inhibitors against nematodes population in soil.  The Advantages of using bionanocide, its safe organic compound extracted from the plant, it has no residual effect, It gives high ability to reach within the roots to combat nematodes in their phases, and the ability of the compound to rapidly spread in irrigation water which also gives the strength to spread and stay in the soilfor a long time. Causing direct death to nematodes after few minutes also has a repellent effect due to the presence of nanoparticles around the roots. There are more than800products as fertilizers worldwide with their effective as nanomaterials, which benefit the plant faster by Increasing photodynamic activity, increasing leaf content of chlorophyll, also product Increase crop capacity to withstand different stress conditions. So Nanomaterials help protect the environment and human health, Increases farm profitability due to reduced fertilizer and spraying costs. Finally Advantage of using Bio-nanotechnology application in agriculture is contributes effectively to increase the productivity of crops, its competitiveness by reducing the residues of fertilizers that economically reflected on farmer field cost, increase export opportunities, more over the development of the new generation of highly specialized save Biocide
