The invention relates to the field of agriculture and is designed to increase the energy of germination, germination and yield of beet and carrot.

It is known the use of para-aminobenzoic acid for presowing treatment of seeds and seedlings of vegetable crops, in particular beetroot and carrot [1].

Know the application of biological drug NICHAN to improve yield and quality of carrot seeds, including seeds treatment [2].

It is known the use of sodium acrylate as a growth promoter for increasing the yield of sugar and fodder beet and green mass of fodder crops, raise blood sugar and reduce nitrate [3].

Known drugs help to increase the yield of beets and carrots. However, they are getting quite complicated and expensive.

The invention is directed to a tool which shows the properties of growth stimulants root crops - beets and carrots, expanding Arsenal of tools for this purpose.

The technical result is to increase the yield of beet and carrot, as well as the expansion of the means of this assignment.

This is achieved using the monohydrate of bis-(diethylamine)duodart-1-hydroxy-ethyl-1,1-diphosphonate (I), having the properties of stimulat the RA growth of root crops

Offer organophosphorus compound get slow evaporation for one month at a temperature of 18-22°at pH 7 product obtained by mixing oksietilidendifosfonovaya acid and diethylamine in the ratio 1:2. The product yield is 60-70%. The crystals are monoclinic at 293K and=12,633(2)A; b=13,784(2)A; c=22.440(4)A, α=102,60(1)0; V=3813,4(2)A3; dthe calc=1,290 g/cm3; Z=8 (two independent molecules), space group P21/C.

Example 1. Seeds of fodder beet varieties Bordeaux soaked in distilled water (control) and in the solution of 0.01 monohydrate of bis-(diethylamine)duodart-1-hydroxy-ethyl-1,1-diphosphonate (I) for 2 hours per 1 l of solution per 1 kg of seeds After soaking the seeds are dried before sowing condition, stored in paper bags and sow. Comparative data on energy of germination are shown in table 1.

On soils with a humus content of 5.7; pH of 6.3, the content of heavy metals - Cu - 192,0; Cd - 2,74; Zn - 176,0 mg/kg were grown culture of red beet cultivar "Bordeaux". The method was carried out with a fourfold repetition. The area of experimental and control plots was 40 meters On the experimental plot in the phase of tillering (at the outlet of 5-6 leaves) once sprayed with a 0.01% aqueous solution of the monohydrate of bis-(diethylamine) duodart-1-hydroxy-ethyl-1,1-depo fonate in the amount of 10 l of 0.01% solution, and on the control plot spraying was carried out. Comparative yield data are shown in table 1.

Example 2. Analogously to example 1 were soaked and planted the seeds of culture carrots "Losinoostrovskaya". Comparative data on the germination and yield are given in table 1.
