The crops seed germination rates, growth of crops and yields and quality of crop products were increased by using nanotechnology for the treatment of seeds. Similarly, different energy of nanomaterials treated water (NMTW) to treat pathogenic fungi of rice diseases, the growth rate of fungal colonies were promoted. The fungicides were diluted with NMTW, and their performance were significantly improved and enhanced, which strengthen the inhibited efficacy to the pathogenic fungi. In this study, the effects of rice disease pathogens, Pyricularia oryzae, Rhizoctonia solani and Gibberella fujikuroi treated with NMTW were assessed. When compared with sterile water, the growth rate of the three rice disease pathogens treated with NMTW was increased from 0.77 to 15.00%. The fungicides were diluted with NMTW the growth inhibiting rate to three rice disease pathogens increased from 7.23-72.13% compared with those fungicides diluted with sterile water.
Experiments in greenhouse and field control efficacy to rice diseases of fungicides diluted with NMTW were being carried out. Preliminary results show a good control effect. It was demonstrated that nanotechnology could be a potential tool for plant protection and production, and will be a green approach for less fungicide and higher level of food safety.
