The invention relates to agriculture and can be used in the plant for cultivation of various crops.

Known use as a means to increase crop yields of plant growth regulators: Agatha 25, immunocytoma, mival, albite, and others belonging to different classes of chemical compounds and biological products [1].

The plant growth regulators increase the height of the stems, the mass of the aerial part and roots, yield, and increase the resistance of plants to adverse environmental factors and diseases.

The task of the invention is to improve the efficiency of regulation of plant growth, yield and resistance to bacterial, fungal and other diseases.

Offered as plant growth regulators to use drugs: peroksigidrat urea (GMP) and peroxide M agro (PGMA) - azotoluene fertilizers, possessing properties of plant protection against pathogens[2, 3, 4].

The method of obtaining the above drugs and their use are known[2, 3, 4, 5].

Drugs PGM, PGM are complex chemical compounds of urea with hydrogen peroxide. PGM consists of the following components: 64,3% urea, 35% hydrogen peroxide and 0.15-0.25% of citric or oxalic acids. In the preparation of PGMA to omnitele made of 0.5-5.0% of sodium tripolyphosphate.

In PGMA in a production environment, it is advisable to make 0.5 to 12% stabilizer (potassium, sodium, and magnesium salts of phosphoric or silicic acid), 0.5 to 0.25 per cent of any surfactant (OP 7, OP-10, twin or kremniiorganicheskie) and/or directly when used in an aqueous solution of the drug to add trace elements (boron, molybdenum, magnesium, copper, zinc, cobalt and others).

PGM, PGM as growth regulators can be used in technological processes of cultivation of potatoes, vegetables (cabbage, cucumber, tomatoes, radish and others), cereals, leguminous crops (barley, wheat, corn, canola, lupins, clover, flax, soy, beans, and other), fruit and berry crops, and ornamental and potted plants in horticulture, floriculture, forest and farmlands, including in the processing of seeds, tubers, seedlings, cuttings, seedlings, above plants in preparation of planting material and for the root and/or foliar feeding of plants.

Drugs used in the form of 0.15 to 3.0% water solutions for the treatment of seeds, tubers, seedlings, etc. before sowing, planting and/or for spraying plants with foliar and/or watering the soil in the root processing.

The plants are sprayed with solution manual, tractor sprayers, and seeds, tubers by hand or by machine.

Below is the data of tests of plant growth regulators PGM, PGM.

Example 1. The impact of PGM in comparison with urea (urea) and control on the growth and development of various varieties of potatoes was carried out on 30 day cultivation during the growing conditions in soil at doses of 50; 100; 200 g/m2is presented in table 1.

The best indicators of the height of stems obtained in the variant of the experiment with the use of PGM in the rate of 50 g/m2. High doses of urea - 200 g/m2- lead to the reduction of weight of aboveground parts of potato plants in comparison with control and options using doses of 50 and 100 g/m2urea accumulation of vegetative mass was negligible.

PGM unlike urea did not show fetotoksicheskoe action on potato plants.

The data obtained indicate the possibility of using peroksigidrat urea and drugs obtained on its basis, in small doses as plant growth regulators.

Example 2. The influence of the drug, PGMA germination of seeds, root system and growth of flowers was investigated in a greenhouse at a temperature of 20-22°C and a humidity of 90%. Flower seeds were sowed in boxes of size 50×70×20 cm into the soil (a mixture of 50% peat and 50% perlite). After sowing, the soil was processed 0.15% aqueous solution of the drug in the rate of 1.0 l on the box. Control - irrigation soil water. The results are presented in table 2.

In the stage of the first true leaf plants were respice ofany in cassettes with cells with a diameter of 30 mm, height of 50 mm and treated twice with an interval of 10 days of 0.15% aqueous solution of PGMA in the rate of 1.0 l on the cartridge. Control - water treatment. Impact on the growth of plants and the number of buds is presented in table 3.

Example 3. Seeds TUI (100 pieces) were planted in boxes of size 70×50×20 cm, filled with soil (a mixture of 50% of raised bog peat and 50% perlite), and were treated with 0.3% aqueous solution of PGMA in the rate of 1.0 l on the cartridge. Control - irrigation soil water.

Grass seeds were planted in soil and watered with 0.3% aqueous solution of PGMA. The effect of the drug on germination, root system and plant height are presented in table 4.

Example 4. Field experience research astragulus properties of PGMA on potatoes was conducted in the experimental field of sue OPH "Korenevo" (pcrescue, Lyubertsy R-n, Moscow region). Studied the effect on germination of tubers, development and productivity of potato varieties, Santa, the defeat of plants and tubers diseases. The area of the experimental plots of 25 m2the repetition of four -, hosted - indonesiafree. Drug PGMA sprayed seed potatoes before planting at a rate of 280 g/t, 10 l of an aqueous solution /Catalan - drug ethyn, identical rate of 20 ml/kg per spraying plants in the phase of "the beginning of a budding" (80 ml/ha). Potato planting was carried out 10.05.2006,, cleaning - 28.08.2006,

The results of the determining biometric measurements of plants in phase "full bloom" is presented in table 5, and productivity of potato plants in table 6.

Treatment of tubers drug has had a stimulating effect on plant height, weight of leaves, the area of leaf surface and the intensity of the education of young tubers compared with standard - Atina and control.

Preparation of peroxide M agro in the field had a positive impact on growth, development and productivity of potato plants.
