Impact of engineered nano silver on root- knot nematode, Meloidogyne incognita and on DNA damage in tomato plants under screen house conditions

Abstract

Root-knot nematodes are one of serious pathogens which cause economically losses to their host plants. Nanotechnology is a fast-growing technology in nematode and other pathogens management to avoid the hazard effects of chemical pesticides and nematicides on human health, non nanoparticles (AgENPs) synthesized by green method using plants with nematicidal properties or reductive potential such as Curcuma comosa (N1), Cycas circinalis investigate the genotoxic evaluation of the four AgENPs and the analysis of its effects through the assessment of pathogenicity and reproductivity of Meloidogyne incognita, enzymes and assessment of DNA damage transplanted, treated with three concentrations of four AgENPs and infected with 1000 IJs condition. The data demonstrated that, all nematode parameters were sup AgENPs. The suppressive effect was increased proportionally with the Ag concentrations. parameters was increased proportionally with concentration of AgENPs. S relatively very low.
