Electrospark method of obtaining metal nanoparticles for the creation of antifungal drugs (fungicides)

Abstract The research is based on the processes of studying electrospark underwater synthesis of conductive metals in a reaction chamber with low conductivity for the production of metal nanoparticles. Experiment had been carried out using confirmation of silver and copper nanoparticles by electron microscopy. The use of nanoforms of metals, in particular nanosuspensions, is considered as an alternative to acutely toxic chemical preparations in crop production for the protection of field crops. Strains of microorganisms – causative agents of diseases of grain crops were used as objects of research. The ultrafine metal phase of metal nanoparticles (particulate nature of matter – PNM) is considered as an alternative to existing agrochemicals based on metal salts. The obtained colloidal solutions of metals have fungicidal properties and can be used to create plant protection products.
