The invention relates to agriculture, it is preferable to technologies of cultivation of cereal crops.

The known method of increasing the sustainability of vegetable crops and potatoes to diseases, including the treatment of the plants with an aqueous solution gibberelline of the drug, which is used as a drug Gibberish, which is a complex of sodium salts gibberellins empirical formula C19H21O6and processing of seeds, tubers, bulbs carried out before sowing for 30 min - 24 h, and the concentration of drug in solution, 50...300 mg/l (RU patent 2195823 C2, IPC701N 63/04. The method of increasing the sustainability of vegetable crops and potatoes to disease. Published 19.01.2003).

The disadvantages of the method include the lack of a proper degree of improvement of plant resistance to a complex of the most important pests and diseases, which is associated with significant costs, in addition, violated the environmental situation of the region.

There is a method of increasing resistance to diseases and pests of plants, including seed treatment with a solution of natural mineral bischofite with a concentration of from 15 to 100 wt.% and consumption 10-18 l/t seed, which is used for seed treatment solution bischofite, activated by a magnetic field with a capacity of 450-800 e used is th at the vegetative (non-root) plant nutrition (RU patent 2243659 C1, IPC701N 59/06. Method of increasing resistance to diseases and pests of agricultural plants. Published 01.10.2005).

The disadvantages of the method include a weak impact on pathogens and pests, rapid loss of activation of the magnetic field when foliar (vegetation) feeding of plants.

This method is adopted as the nearest equivalent.

The essence of the claimed invention.

Task to be solved by the claimed invention is directed to develop a way that ensures the destruction of pathogens, pests and creating favorable conditions for the growth and development of plants, improve yield.

The technical result - favorable conditions for the growth and development of plants, higher yields.

This technical result is achieved by the fact that the proposed method of increasing the yield and sustainability of cereal crops to diseases, pests includes processing of grain crops in the tillering period (the beginning of the tube) environmentally friendly means of electroactivated aqueous solution of anolyte, which is processed in the anode chamber of an installation for the electrochemical activation of water with a positive potential the redox potential of +600...+700 mV and the rate of flow of anolyte 100...150 l/ha/p>

Due to the fact that water passing through the anode chamber for electrochemical activation, acquires a new acid-base, redox and catalytic properties of dilute solutions and water can be used such metastable liquid instead of the traditional solutions of chemical reagents in technology increase the immunity of cereal crops. Water treated in the anode chamber electroactuator, gets increased acidity, which provides for the destruction of pathogens and pests that favorable conditions for normal growth and development of plants, as well as to increase yields.

The method is as follows.

To implement the method uses trailed boom sprayer OP-2000-2 or hinged OM-630, MD 320, HE-400, which Dobroudja a DC generator or an AC generator with rectifier and electroactivation. The capacity of the sprayer before work is filled with water. On the pressure line providing water supply to the rod with sprayers, mounted elektroaktivator, which is connected to the DC generator.

When the sprayer is moving across the field, the pump takes the water from the tank and delivers it to electroa tiator, which affects the flowing water, resulting produced the anolyte and catholyte is positively charged and negatively charged water - anolyte is fed into the rod sprayers that produce processing plants. The redox potential of the anolyte is produced within +600...+700 mV.

Arriving at the leafy part of plants at the tillering period - the beginning of the tube - analyte affects pathogens and pests, so that they die and the plant creates a healthy phytosanitary condition of the agricultural landscape, allowing for crops with high environmental performance. Produced by electroactivation catholyte is served in the basal part of the plant than is achieved biological activation operation of the root system and provide additional conditions to improve yield.

The results of the comparative tests are given in the table.
