FIELD: agriculture.SUBSTANCE: preparing a concentrated solution carried copper fungicides by dissolving the water-insoluble copper-containing substance, which is a basic copper carbonate, in an aqueous ammoniacal ammonium carbonate solution to form a complex compound, completely soluble in water, is a copper-ammonium carbonate complex. Then, by diluting a concentrated solution of copper containing fungicide with water to prepare the working solution is a copper containing fungicide. Spend processing plants by spraying. After the treatment is the destruction of the copper-ammonia carbonate complex in the process of drying the solution on the surface of the plant to form a water-insoluble plaque which is a basic copper carbonate crystals. With the destruction of the copper-ammonium carbonate complex is released ammonia partial assimilation of its processed plant as a foliar ammonium-nitrogen fertilizer.EFFECT: invention allows to shorten the process.5 cl, 1 ex |
