However, the composition is not sufficiently effective.

Closest to the proposed invention is a composition for stimulating the growth of agricultural crops, including alkanolamine, molybdenum compounds, with the unity of copper and water (patent No. 2162285, IPC A01N 59/20, 2001). The composition is insufficient.

The present invention is highly effective composition for stimulating growth and development of crops and the expansion of the range of compositions due to the high selectivity of the plants.

The problem is solved so that the composition for stimulating growth and development of crops, including molybdenum compounds, copper compounds, alkanolamine and water, as compounds of molybdenum contains ammonium molybdate or molybdenum acid, or molybdenum trioxide, copper - copper sulfate or copper acetate, or citrate copper, or copper carbonate basic, as alkanolamine monoethanolamine, or diethanolamine, or triethanolamine and optionally contains citric acid at a molar ratio in the mixture: molybdenum compounds, copper compounds: citric acid: alkanolamine equal to 1:(2-8):(1-10):(4-80) and in the following ratio, wt.%:

Example No. 1 (proposed).

Mix of 5.25 g of citric acid, 5.8 g of ammonium molybdate, and 9.5 g of copper citrate, 64 g of water and 14.9 g of triethanolamine. The mixture was thoroughly stirred to obtain a homogeneous product. (The molar ratio of active components, Mo: Cu: citric acid: tea=1:2:1:4.)

Example No. 2.

Mix 45.6 g of water, to 13.1 g of citric acid, of 10.9 g of copper acetate, 30.5 g of monoethanolamine and 0.9 g of molybdenum trioxide. (The molar ratio of active components, Mo: Cu: citric acid: IEA=1:8:10:80.)

Example No. 3.

Mix 61 g of water, to 13.1 g of citric acid, 5.5 g of copper carbonate basic, and 18.3 g monatana the amine and 2.5 g of ammonium molybdate. (The molar ratio of active components, Mo: Cu: citric acid: IEA=1:4:5:24.)

Examples No. 4-5 carried out analogously to example No. 1, changing the qualitative and the quantitative ratio of the components. The composition of the obtained compounds are shown in table 1.

The resulting compositions are transparent liquid dark blue color with a pH of 9-12 and are concentrate fertilizer mixture.

Example No. 7(ed. mon. No. 184063).

To 10.5 g of citric acid added to 89.5 g of water and mix thoroughly.

The data below are for testing the proposed composition for foliar feeding of plants by growing them in the open or closed ground.

The test results of samples of the composition shown in table 2.

Analysis of the data presented in tables 2 shows that the proposed formulation is more effective in comparison with prototype: it provides higher yields of agricultural crops, high yield products, and also allows you to expand the range of compositions for stimulating the growth and development of crops, which is necessary due to the high selectivity of the plants.
