The invention relates to inorganic chemistry, peroxides and agriculture, plant cultivation, medicine, sanitation and hygiene. The method and device for producing an environmentally friendly solution of hydrogen peroxide from water with a concentration exceeding the natural one in a reactor filled with water, consist in the fact that an electrode made of an electrically conducting material is installed above the water surface. The electrode is connected to the high-voltage terminal of a Tesla resonant transformer, and an electrode is supplied electric energy from a Tesla transformer with a voltage of 1-1000 kV and a frequency of 1-1500 kHz. The streamers of an electric discharge between the electrode, the air and the water surface are created with the formation of hydrogen peroxide in the water. While the reactor of closed or open types contains connecting pipes for supplying water and draining the hydrogen peroxide solution, which is intended for sanitization without dilution, disinfection and disinsection, and after dilution to a natural concentration, stimulates the growth and the development of plants.

An environmentally friendly solution of hydrogen peroxide of natural concentration can be used to increase the yield of cereals, melons and vegetables, as well as gardens and vineyards. The use of the obtained environmentally friendly solution of hydrogen peroxide is possible in medical practice for internal use.
